All can use moulding molding.During oil pump assembling, inlet cap is enclosed within the outside of bottom end cover interface, and seam compresses oil sucting valve
Sheet and the first valve plate, then use glue sealing in the gap of two end caps.Outlet end cap is enclosed within the inside of bottom end cover interface, connects
Compressing oil extraction valve block and the second valve plate at Kou, then with glue sealing in the gap of two end caps, manufacturability is preferable.
As it is shown in fig. 7, present invention also provides a kind of linear compressor, according to the embodiment of the linear compressor of the application
Including compressor body 100 and the oil pump assembly 200 being connected on compressor body 100, oil pump assembly 200 is above-mentioned oil pump
Assembly.
As it is shown in fig. 7, compressor body 100 includes that cylinder frame, cylinder frame are made up of two parts: core is cylinder, outer rim
Part is support.Support is mainly used in supporting motor and other Pump Body Parts；Cylinder is the working chamber of compression cold-producing medium, low pressure gas
Body is at the most compressed formation gases at high pressure, and then the air bleeding valve through end is discharged, and enters pipe-line system and forms kind of refrigeration cycle.Gas
Cylinder and support can use integral cast molding.
Gang Jia edge is provided with oil pump mounting groove, is used for installing and fixing oil pump.Set at end face support and cylinder junction
There is one wide 2～5mm, deep 10～the annular oil cavity of 25mm.Refrigeration oil is after oil pump is discharged, first through internal stent straight trough at ring
Shape oil pocket stores, on the one hand can reduce head temperature, be conducive to increasing the heat transfer effect of cylinder head, improve the effect of compressor
Rate.On the other hand, annular oil cavity can reduce cylinder head assembly bolt fastening time cylinder bores deformation.Subsequently on cylinder frame
Straight trough, simultaneously lubricating oil flow into annular oil cavity, and liquid storage herein with absorb cylinder wall surface heat, then through skewed slot enter
To cylinder interior annular oil groove and herein, oil storage is used for lubricating cylinder and piston, is finally discharged by oil circuit outlet and returns to compression
In machine lower casing.
When linear electric motors drive piston to do horizontal reciprocating movement in cylinder, compressor movement can be driven to vibrate, this
Vibration passes to the oil pump oil cylinder being fixed on compressor so that oil cylinder also does horizontal reciprocating movement, at inertia force and spring
Under effect, alternately opening and close oil sucting valve and draining valve, lubricating oil is inhaled into and discharges oil cylinder through fuel sucking pipe, the oil of discharge
Enter into inside compressor, supply piston and the friction portion of cylinder.
When movement vibrates, oil piston is really static.According to the relation of relative motion, selection movement is object of reference,
Then the vibration of oil pump can regard that oil piston vibrates relative to the reciprocating machine of oil pump housing as.Oil piston and bottom end cover, oil suction group
Part forms oil compression chamber together with oil extraction assembly.When piston relative to oil pump housing in the horizontal direction to left movement time, oil compression
Cavity volume reduces, and intracavity oil pressure raises, and now draining valve is opened, and oil sucting valve is closed, and the lubricating oil of intracavity is discharged to outside oil pump
Portion enters into cylinder frame, completes the lubrication to friction pair along oil circuit, and takes away partial heat.When piston relative to oil pump housing at water
When square upwards moving right, oil compression cavity volume increases, and intracavity oil pressure reduces, and now draining valve cuts out, and oil sucting valve is opened,
The lubricating oil of compressor is drawn into the compression chamber within oil pump by inlet valve.Along with oil piston horizontal direction past
