A vent assembly for use on a tank containing liquid fluid requiring venting, the assembly comprising: a vent portion that includes a top surface, and at least one venting channel, each venting channel capable of providing fluid communication between a tank on which the vent portion is disposed and atmosphere external the tank, the channel having an exit to atmosphere that is disposed on the vent portion below the top surface of the vent portion.
Description
- This application claims priority to and the benefit of U.S. provisional patent application No. 60/741,132, filed Nov. 30, 2005, entitled CAP FOR FUEL TANKS, which is hereby incorporated by reference for all purposes as if included herein in its entirety.
- The inventive subject matter relates to a vented cap and other vent assemblies primarily for tanks containing liquids that require venting. The inventive subject matter is particularly directed to venting fuel tanks used with motor vehicles. The fuel tank may be for holding gasoline, diesel, alcohol, and other liquid fuels for an internal combustion engine. In certain respects, the inventive subject matter relates to a vented fuel cap having a rollover valve, or check valve for use with fuel tanks on motor vehicles.
- Fuel tanks for many motor vehicles include direct venting so a vacuum doe not form in the tank as fuel is withdrawn by an associated motor or engine. A problem with such fuel tanks is that if tank is tipped or turned over, the fuel in the fuel tank can leak out of the vent holes in the fuel cap potentially causing disastrous results. This is particularly problematic for off-road vehicles, such as motorcycles and all terrain vehicles, which are especially at risk of tipping or turn over.
- Vented fuel caps are known that include an angle-dependent valve, such as a rollover or check valve device that operates to prevent fuel from leaking from the vents holes of the fuel cap when a fuel tank is tipped or turned over. For example, one known fuel cap includes a hose that extends outwardly from the center of the fuel cap that includes a rollover, or check, valve device at the end of the hose distal from the fuel cap. While a vented fuel cap of this type generally operates as designed, problems may still occur. For example, if the hose breaks, the check valve functionality may be lost. Also, for example, the hose and rollover-valve device can inflict a puncture-wound to a rider sitting in proximity to the tank.
- Another known vented fuel cap includes a rollover-valve device located under the cap portion of the fuel cap and has a venting hole that emerges through the top side of the cap portion. There are problems with this arrangement too. For instance, the venting-hole arrangement can become clogged with dirt or other debris, eliminating the benefits of the venting hole.
- In view of the foregoing and other problems, there is a need for improved caps for fuel tanks that have an angle-dependent valve, such as a rollover or check valve device that is not easily blocked or broken, and do not present a potential source of a puncture-wound injury.
- A vent assembly for use on a tank containing liquid fluid requiring venting, the assembly comprising: a vent portion that includes a top surface, and at least one venting channel, each venting channel capable of providing fluid communication between a tank on which the vent portion is disposed and atmosphere external the tank, the channel having an exit to atmosphere that is disposed on the vent portion below the top surface of the vent portion.
- These and other embodiments are described in more detail in the following detailed descriptions and the figures.
- The foregoing is not intended to be an exhaustive list of embodiments and features of the present inventive concept. Persons skilled in the art are capable of appreciating other embodiments and features from the following detailed description in conjunction with the drawings.
- The inventive subject matter is illustrated by way of example and not by limitation in the accompanying figures in which like reference numerals indicate similar elements and in which:
-
FIG. 1 depicts a side cross-sectional view of an assembled fuel cap according to the inventive subject matter; -
FIG. 2 depicts an side cross-sectional exploded view of a fuel cap according to the inventive subject matter; and -
FIG. 3 depicts a top view of a slotted disc according to the inventive subject matter. -
FIGS. 1 and 2 depict a ventedfuel cap 100, according to one possible embodiment of the inventive subject matter. The cap has an angle-dependent valve, which as used herein means a valve or other flow restrictor that is provided in the cap to block fluid from flowing from a tank and out of a channel used for venting the tank, the flow being blocked upon a predetermined tilting of the cap from an initial position, which typically is an upright position on top of a fuel tank (as represented by the orientation ofcap 100 inFIG. 1 ). A typical angle-dependent valve is a rollover valve or check valve, and the following discussion will be in terms of such a construction. -
Fuel cap 100 includes acap portion 101, aslotted disc 102, avalve assembly 103, asplash cover 104, and agasket 125. Valveassembly 103 operates to prevent fuel from leaking throughventing channels 107 in the fuel cap when a fuel tank on which the fuel cap is installed is tipped sufficiently or turned over. Motor vehicles that are particularly prone to tipping or turn over include motorcycles, ATVs, personal watercraft, and other recreational, transport or work vehicles that are prone to tipping or turnover, particularly those where the rider and/or fuel tank is unenclosed. -
Cap portion 101 includes atop surface 101 a, abottom surface 101 b, aninner surface 105, avent chamber 106,vent channels 107 with exit openings, communicating with the atmosphere external to thetank 200,threads 108 and threadedblind holes 109.Inner surface 105 receivesslotted disc 102 whenfuel cap 100 is assembled.Vent channels 107 are in venting communication with a fuel tank viavent chamber 106 and extend away fromtop surface 101 a and emerge frombottom surface 101 b. While two vent channels are depicted, it should be understood that any number ofvent channels 107 can be used. Additionally, whilechannels 107 are depicted as emerging frombottom surface 101 b, it should be understood thatchannels 107 can emerge from a surface that is belowtop surface 101 a.Threads 108 engage with corresponding threads of a fueltank filler neck 200.Cap portion 101 is typically formed from any suitable material, such as aluminum, that is sufficiently strong and durable to function as a cap for a fuel cap assembly. - As shown in
FIG. 3 , slotteddisc 102 includes avent passage 110,venting aperture 111, andscrew apertures 112. When slotted disc is received byinner surface 105 ofcap portion 101,vent aperture 111 is in venting communication withvent chamber 106 throughvent passage 110. Whilevent passage 110 is depicted as generally transversing slotteddisc 102 in a bisecting configuration, it should be understood thatvent passage 110 could have any of a number of configurations, such as at least one or more radially configured vent passages. Additionally, slotteddisc 102 can be formed from any suitable material, such as aluminum, that has sufficient strength and durability to be held againstcap portion 101. -
Valve assembly 103 is a gravity-sensitive valve arrangement that blocks a passage based on a predetermined amount of tilting. In one possible example, a suitable valve arrangement is a check valve that includes avalve mount 113, aball valve seat 114, aball 115 and a return-air valve 116. Valvemount 113 is held againstsurface 117 of slotteddisc 102 byscrews 118 passing throughapertures 119 invalve mount 113 andapertures 112 of slotted disc.Screws 118 are received in threadedblind holes 109 incap portion 101.Ball valve seat 114 is received incavity 120 ofvalve mount 113.Cavity 120 is then in venting communication withvent aperture 111 of slotteddisc 102.Ball 115 is received invent cavity 121 ofball valve seat 114.Vent cavity 121 is in venting communication withcavity 120.Ball 115 can be made from any suitable material that is denser and therefore heavier than the fuel that will be contained in the fuel tank on whichfuel cap 100 will be used. Return-air valve 116 is also received invent cavity 121 ofball valve seat 114, thereby retainingball 115 withinvent cavity 121. The components ofvalve assembly 103 can be formed from any suitable material, such as aluminum, that provides sufficient strength and durability to operate as a rollover (check) valve assembly. -
Splash cover 104 includes abarb engagement slot 122 andvent channels 123.Barb engagement slot 122 engagesbarb 124 onvalve mount 113, thereby fixedly holdingsplash cover 104 aboutvalve assembly 103.Splash cover 104 can be formed from any suitable material, such as plastic, that provides sufficient strength and durability to be used as a splash cover for a vented fuel cap. -
Gasket 125 fits intocap portion 101 and forms a seal with the filler neck of the fuel tank.Gasket 125 can be formed from any suitable gasket-type material, such as rubber. - In a typical operation,
fuel cap 100 is installed in the filler neck of a fuel tank of a vehicle in a well-known manner so that fuel cap seals the fuel tank. - When the fuel tank and
fuel cap 100 are in a normal, upright position, there is a vent passage throughvent channels 123, return-air valve 116,vent cavity 121,cavity 120,vent aperture 111,vent passage 110,vent chamber 106 andchannels 107. In the normal, upright position,ball 115 sits on return-air valve 116, thereby allowing normal venting to occur. - When the fuel tank and
fuel cap 100 are in a sufficiently tilted or an inverted position,ball 115 closes ventcavity 121, thereby preventing fuel from spilling fromfuel cap 100 throughvent channels 123, return-air valve 116,vent cavity 121,cavity 120,vent aperture 111,vent passage 110,vent chamber 106 andchannels 107. - While the inventive subject matter has been discussed in terms of a removable cap, a tank might be constructed with a fixed section incorporating an angle-dependent valve as contemplated herein. The tank could, for example, include a separate openable cap or other mechanism for adding or draining fluid from the tank, in addition to the fixed valve assembly. Accordingly, instead the inventive venting features of the cap may be instead implemented as a fixed “venting portion” on a tank.
- Persons skilled in the art will recognize that many modifications and variations are possible in the details, materials, and arrangements of the parts and actions which have been described and illustrated in order to explain the nature of this inventive concept and that such modifications and variations do not depart from the spirit and scope of the teachings and claims contained therein.
