An object of a broad aspect of this invention is to provide a filter hose which preforms dual functions, when used as a part of a vehicle assembly having internal combustion engine, firstly of conducting inlet air from a location within the vehicle to the engine intake system, and secondly of filtering such induction air without requiring a separate air filter housing.
A first broad aspect of this invention provides a filter assembly which includes an impervious elongated tubular housing having an internal substantially circular tubular surface, an inlet end and an outlet end. 'the filter assembly also includes an elongated filter member having opposed first and second surfaces, opposed longitudinal edges, and first and second ends. The elongated filter member is of length not greater than the housing.
The elongated filter member further is positioned within the housing with the opposed longitudinal edges in contact with, and sealably secured to, the internal tubular surface of the housing. The filter assembly also includes a first barrier which is interposed between the first surface of the filter member and the internal tubular surface of the housing adjacent the first end of the filter member. Finally, the filter assembly also includes a second separate barrier which is interposed between the second surface of the filter member and the internal tubular surface of the housing adjacent the second end of the filter member.
By a first variant of this first broad aspect of this invention, the tubular housing and the filter member are flexible.
By a second variant of this first broad aspect of this invention, and/or this first variant thereof, the filter assembly includes circumferential reinforcing means on the tubular housing adjacent to at least one of the inlet and outlet ends.
By a third variant of this first broad aspect of this invention, and/or the above variants thereof, the filter member is formed of an elongated sheet of filter media. By a first variation thereof, the elongated sheet of filter media is pleated into a lengthwise undulating pattern.
A second broad aspect of this invention provides a filter assembly which includes an elongated hollow housing having an internal, substantially-circular circumferential surface, an inlet end and an outlet end. The filter member also includes an elongated filter member having opposed first and second surfaces, opposed longitudinal edges, opposed ends, and which is of length not greater than the length of the housing. The filter member is positioned within the housing with the longitudinal edges in contact with, and sealably secured to, the internal circumferential surface of the housing. This, thereby provides first and second spaces between the first and second surfaces of the filter member and the internal circumferential surface of the filter member. The filter member includes means for closing the first space which is adjacent to the inlet end of the housing.
Finally, the filter member includes separate means for closing the second space which is adjacent to the outlet end of the housing.
By a first variant of this second broad aspect of this invention, the tubular housing and the filter member are flexible.
By a second variant of this second broad aspect of this invention, and/or this first variant thereof, the filter assembly includes circumferential reinforcing means on the tubular housing adjacent to at least one of the inlet end and the outlet end.
By a third variant of this second broad aspect of this invention, and/or the above variants thereof, the filter member is formed of an elongated sheet of filter media. By a first variation thereof, the elongated sheet of filter media is pleated into a lengthwise undulating pattern.
A third broad aspect of this invention provides a filter assembly which includes an elongated tubular housing having a substantially-circular internal tubular surface, an inlet end and an outlet end. The filter assembly further includes an elongated filter member positioned within, and having opposed longitudinal edges in contact with and sealably secured, to the internal tubular surface of the housing, thereby dividing the interior thereof into first and second areas. The filter assembly further includes means which are adjacent the inlet end of the housing closing the first area. Finally, the filter assembly includes separate means which are adjacent to the outlet end of the housing closing the second area, whereby a fluid flowing through the housing from the inlet and to the outlet end must pass through the filter member.
By a first variant of this third broad aspect of this invention, the tubular housing and the filter member are flexible.
By a second variant of this third broad aspect of this invention, and/or this first variant thereof, the filter assembly further includes reinforcing means on the tubular housing adjacent to at least one of the inlet end and the outlet end.
By a third variant of this third broad aspect of this invention, and/or the above variants thereof, the filter member is formed of an elongated sheet of filter media. By a first variation thereof, the elongated sheet of filter media is pleated into a lengthwise undulating pattern.
A fourth broad aspect of this invention provides a filter assembly which includes an impervious elongated flexible housing having a wall of relative uniform thickness and an internal tubular surface, an inlet end and an outlet end. The filter assembly also includes an elongated flexible filter member having opposed first and second surfaces, opposed longitudinal edges and first and second ends, the elongated filter member being of length not greater than the length of the housing, the elongated filter member being positioned within the housing with the opposed longitudinal edges in contact with, and sealably secured to, the internal tubular surface. The filter assembly also includes a first barrier which is interposed between the first surface of the filter member and the internal tubular surface of the housing in the direction towards the inlet end of the filter member. Finally, the filter assembly includes a separate second barrier which is interposed between the second surface of the filter member and the internal tubular surface of the housing in the direction towards the outlet end of the filter member.
By a first variant of this fourth broad aspect of this invention, the tubular housing is substantially-circular in cross-section.
By a second variant of this fourth broad aspect of this invention, and/or this first variant thereof, the filter member is formed of an elongated sheet of filter media.
By a third variant of this fourth broad aspect of this invention, and/or the above variants thereof, the elongated sheet of filter media is pleated into a lengthwise undulating pattern.
By a fourth variant of this fourth broad aspect of this invention, and/or the above variants thereof, the circumferential reinforcing means on the tubular housing adjacent to at least one of the inlet end and the outlet end.
As described above, one broad aspect of this invention is constituted by a filter assembly in the form of an elongated impervious tubular housing that is preferably in the form of a semi-rigid elastomeric hose. The hose may be of various cross-sectional arrangements but preferably is circular thereby to allow maximum flexibility.
An elongated filter member is positioned within the tubular housing. The filter member has opposed first and second surfaces, opposed longitudinal edges, a first and a second end. The longitudinal opposed edges of the filter member are sealed to the internal tubular surface of the housing.
The edges of the filter member may be sealed by bonding, by adhesive or the edges can be encapsulated in the elastomeric material of which the tubular housing is formed. One method of manufacturing the filter assembly is to injection mould the tubular housing around the filter member to thereby encapsulate the longitudinal edges.
A first barrier is positioned within the tubular housing at the filter member first end.
The first barrier is configured sealably to engage the first surface of the filter member and the interior tubular surface of the tubular housing that is opposed to the first surface of the filter member. The first barrier therefore leaves an open space at the first end of the filter member between the second surface of the filter member and the internal tubular surface of the housing.

In a similar manner, a second barrier is interposed between the second surface of the filter member and the internal tubular surface of the housing adjacent to the second end of the filter member. Induction air entering the housing inlet end must pass through the filter member before exiting at the housing outlet end.
The filter member is preferably formed of a sheet of polyester non-woven filter media. Further, the filter member sheet is preferably pleated lengthwise thereby substantially to increase its cross-sectional area. The first and second barriers may be formed of impervious, relatively-thin, plastic plates which are bonded at one edge to the filter media and at the opposed edge to the interior wall of the tubular housing. Another embodiment is to form the first and second barriers of filter material, e.g., a sheet of polyester non-woven filter media.
It has been found that the fitter hose of aspects of this invention performs dual functions, when used as a part of a vehicle assembly having internal combustion engine.
The first function is of conducting inlet air from a location within the vehicle to the engine intake system. The second function is of filtering such induction air without requiring a separate air filter housing.

(t7 AT LEAST ONE MODE FOR CARRYING OUT THE INVENTION
Referring to the drawings and firstly to Figures 'I and 2, the basic concepts of aspects of the invention are illustrated.
Figure 1 shows a tubular housing containing an elongated pleated filter member. The elongated edges of the filter member are affixed to the internal wall of the tubular housing.
The tubular housing is shown curved, indicating that it may be semi-rigid or flexible.
Figure 1 is shown broken away since the length of the filter hose assembly can vary as required.
In Figure 2, the barriers form a flow path through the tubular housing requiring air entering the inlet end to flow through the filter member before exiting the outlet end.
An impervious elongated tubular housing 10 has an internal tubular surface 12, an inlet end 14 and an outlet end 16. 'Tubular housing 10 may be of a variety of cross-sectional configurations, e.g., square, elliptical, circular, and so forth. However, a circular configuration as illustrated in Figures 1 and 2, except for special applications, is the preferred embodiment. By use of a circular cross-sectional configuration, tubular housing 10 can be made to be equally flexible in any direction, thus more readily adapting the air induction filter hose assembly to a variety of spacial applications.
The tubular housing 10 is preferably formed of an elastomeric material. While housing 10 may be rigid or substantially-rigid, the preferred embodiment is that housing 10 be semi-rigid. That is, the housing should have sufficient structural rigidity substantially to maintain its cross-sectional configuration but, at the same time, permit the housing to be bent or curved at least slightly along its longitudinal tubular axis so as to accommodate space requirements which are commonly encountered when the filter hose assembly is used to filter induction air for an internal combustion engine.
Positioned within tubular housing 10 is an elongated filter member 18. The elongated filter member 18 has a first surface 20, an opposed second surface 22, opposed longitudinal edges 24 and 26 (best seen in Figure 3), a first end 28 and a second end 30.
The length of the elongated filter member 18 is not greater than the length of tubular housing 10 and is illustrated as being somewhat shorter than that of tubular housing 10. The first end 28 of the elongated filter member 18 is adjacent to the inlet end 14 of the tubular housing, and the second end 30 of the elongated filter member 18 is adjacent to the outlet end 16 of the tubular housing.
The longitudinal edges 24 and 26 are secured to tubular surface 12 of tubular housing 10. This can be accomplished, e.g., by bonding with an adhesive, or the tubular housing may be injection moulded around the elongated filter member 18 so that the edges 24 and 26 of the elongated filter member are encompassed within the tubular housing, as illustrated in Figure 3. Any mechanism by which the longitudinal edges of the elongated filter member 18 are permanently secured to the interior wall is within the scope of broad aspects of this invention.
The elongated filter member 18 divides the interior of tubular housing 10 into a first space 32 that exists between first surface 20 of the elongated filter member 18 and the interior tubular surface 12 and, in like manner, a second space 34 that extends between the second surface 22 of the elongated filter member 18 and interior tubular surface 12 of the housing.
To define flow paths within the air induction hose assembly, a first barrier 36 is secured to the second surface 22 of the elongated filter member adjacent to the first end 28 and to the internal tubular surface 12 of the tubular housing 10 adjacent to the first or inlet end 14 (as seen at the left end of Figure 2). In like manner, a second barrier 38 is secured between the first surface 20 of the elongated filter member and the interior tubular surface 12 of tubular housing 10 adjacent to the second end 30 of the elongated filter member 18, i.e., adjacent to the second or outlet end 16 of the housing (seen at the right hand end of Figure 2).
The cross-sectional configuration of the filter member 18 may vary considerably. In the preferred arrangement, the elongated filter member 18 is formed of a flat sheet of thick, high-loft polyester non-woven filter media. This flat sheet is preferably pleated as illustrated in the figures. Pleating is commonly employed in filtration equipment substantially to increase the cross-sectional area of the filter media. It is obvious that the cross-sectional area of the filter media for a given diameter and length of tubular housing can be dramatically increased by increasing the height of the pleating as well as b;y increasing the number of pleats employed.
The first and second barriers 36 and 38 may be formed of thin impervious material, e.g., sheet plastic material, or may be formed of filter media. That is, they may be formed of sheets of a polyester non-woven filter media that is bonded to the elongated filter member 18 and to the internal tubular surface 12 of the tubular housing 10.
Figure 4 illustrates, by arrows, the path of flow through the filter from the inlet end 14 to outlet end 16. The aspect of the air induction filter hose assembly as illustrated and described herein is particularly adapted for use to provide induction air to an internal combustion engine, e.g., for automobiles, trucks and so forth. However, the invention in its broad aspects may be employed for purposes other than air filtration.
The elongated filter member 18 may be supported by the use of top and bottom combs (not shown), or other kinds of standoff may be employed to provide structural rigidity of the filter member as necessary. Such combs or standoffs, when used, will be constructed so as to provide minimum interference with the flow paths.
The embodiment of Figure 4 shows integral reinforcing tubular ribs 40, e. g. , circumferential ribs, which are formed adjacent to the inlet and outlet ends 14 and 16 of the tubular housing 10. These are illustrative of the fact that the tubular housing 10 may be designed to receive clamps or other apparatus by which the ends of the tubular housing 10 may be attached to other components in an automobile or truck assembly, or for other applications. While not illustrated, the tubular housing 10, obviously, could include metallic or rigid plastic structural reinforcing components as an integral part thereof to maintain the configuration of the tubular housing adjacent the ends for better connection to other apparatuses.
The aspect of the air induction filter hose assembly as herein described offers many advantages over the standard type of air filtration used in automobiles, trucks and so forth.
Firstly, by combining the filtration system with an air induction hose, two functions are concurrently achieved by the same apparatus, thus reducing space and weight requirements.
Secondly, the filtration system employed integrally with the air induction hose means that air velocity will be maintained at a substantially-consistent rate throughout the induction passageway, as compared with other filtration systems wherein an induction hose connects to a housing in which a filter element is located.
As previously stated, the edges 24 and 26 of the filter member can be bonded to, or be encompassed within, the interior tubular surface of the tubular housing 10.
Figures 1 and 2 show, on the exterior surface of the tubular housing 10, areas 42 which are opposed to the interior surface where the filter member edges are embedded. As a practical matter, depending upon the type of construction employed, exterior visual indication of the area where the filter member edges are encompassed may or may not exist.
