It is characterized in that a cylinder bottom gasket, a step hole, an arch-type surface of the cylinder cover, a reset spring, a valve base plate, a pressure release valve plate, a pressure release groove, an air outlet valve plate are also included in the model. The cylinder bottom gasket is provided on the side of the air inlet cavity to work as an pressure release valve port, the pressure release valve plate is arranged beneath the cylinder bottom gasket, a rest spring is connected under the pressure release valve plate, and is embedded in the pressure release groove; the pressure release valve plate, the pressure release groove, together with the reset spring form an integral structure, which is embedded in the valve base plate, the step hold is arranged on the side of the air outlet cavity, and is connected with the air outlet valve plate in order to position it.
Description
Technical field
The utility model relates to a kind of automobile-used air compressor cylinder cap assembly, belongs to the air compressor field.
Background technique
The structure of present automobile-used air compressor Reed Valve cylinder cap assembly is generally air-intake valve plate and is supported on the cylinder liner both sides in the seat board bottom with two positioning pin holes location and both sides, with pad push down on one side, another side is removable; And exhaust valve plate is arranged in the seat board top, exhaust valve plate one end is fixed by deciding the journey plate with two bolts, and another side adds a small washer, make exhaust valve plate can lift certain altitude and mobile in a small amount at axial direction, promptly an end is fixed, one end is floating type, and air inlet pine laminated structure is arranged in air-inlet cavity, pass through plunger, axle, spring and three O type circles are formed a pressure balancing system, make that plunger can not be lifted in the process of calming the anger, pressurized air entered into the middle air cavity of plunger when pine was pressed by pressure gas inlet, move on the area official post plunger by last lower plunger, the plunger bottom surface breaks away from seat board, makes the piston head chamber by valve seat plate hole and cylinder cap air-inlet cavity UNICOM, thereby the realization off-load is as figure one.During said structure uses, exhaust valve plate because when distortion stress bigger, phenomenon of rupture can appear, and loose laminated structure, because complex structure, three O type circles make resistance too big, often to produce the chance of clamping stagnation bigger because of chemical factor, insufficient lubrication, grease lost efficacy, enter foreign matter factors such as (as carbon distributions), make air compressor or not off-load behind the clamping stagnation, cause temperature too high, or do not inflate.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provides the original O type of a kind of cancellation circle, can not cause the automobile-used air compressor cylinder cap assembly of catching phenomenon.
The technical solution of the utility model is achieved in that a kind of automobile-used air compressor cylinder cap assembly, comprise cylinder cap, the pressure loosening valve valve rod, air-inlet cavity and exhaust cavity, also comprise gland shim, shoulder hole, the cylinder cap bow shaped surface, return spring, seat board, the pressure loosening valve sheet, pressure loosening slot, exhaust valve plate, wherein the gland shim side that is installed in air-inlet cavity is used for doing the pressure loosening valve mouth, the pressure loosening valve sheet is installed below the gland shim, connect return spring below the pressure loosening valve sheet, return spring embeds in the pressure loosening slot, the pressure loosening valve sheet, on the overall structure inserted valve seat plate that pressure loosening slot and return spring are formed, shoulder hole is arranged on the side of exhaust cavity, be connected with exhaust valve plate, be used to locate exhaust valve plate.
Described return spring is a conical helical spring.
Compared with prior art, the beneficial effects of the utility model are: owing to cancelled O type circle, can not cause catching phenomenon because of the factor of O type circle, reduce the exhaust valve plate distortional stress.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.But conduct is not to qualification of the present utility model.
As shown in Figure 1, existing automobile-used air compressor cylinder cap assembly, cylinder cap 5 mainly is by plunger 1, axle 2, spring 3 and three O type circles 4 are formed a pressure balancing system, make that plunger 1 can not be lifted in the process of calming the anger, pressurized air entered into plunger 1 middle air cavity by pressure gas inlet 6 when pine was pressed, move on the area official post plunger 1 by last lower plunger 1, but exhaust valve plate because when distortion stress bigger, phenomenon of rupture can appear, and loose laminated structure, because complex structure, three O type circles 4 make resistance too big, often because of chemical factor, insufficient lubrication, Deng producing catching phenomenon, make air compressor or not off-load cause temperature too high behind the clamping stagnation, or do not inflate.
As Fig. 2, Fig. 3, shown in Figure 4, a kind of automobile-used air compressor cylinder cap assembly, comprise cylinder cap 5, pressure loosening valve valve rod 13, air-inlet cavity 16 and exhaust cavity 17, also comprise gland shim 7, shoulder hole 8, cylinder cap bow shaped surface 9, return spring 11, seat board 12, pressure loosening valve sheet 10, pressure loosening slot 14, exhaust valve plate 15, vertical top type is partly used in the air inlet off-load instead, cancel all O type circle, in order to make compact structure and to improve reliability, wherein gland shim 7 side that is installed in air-inlet cavity 16 is used for doing the pressure loosening valve mouth, pressure loosening valve sheet 10 is installed below the gland shim 7, connect return spring 11 below the pressure loosening valve sheet 10, return spring 11 embeds in the pressure loosening slot 14, pressure loosening valve sheet 10, on the overall structure inserted valve seat plate 12 that pressure loosening slot 14 and return spring 11 are formed, shoulder hole 8 is arranged on the side of exhaust cavity 17, be connected with exhaust valve plate 15, be used to locate exhaust valve plate 15.
Cylinder cap bow shaped surface 9 controls on the lower end surface of the pressured cast aluminium cylinder cap of the lift of exhaust valve plate 15, make the both sides of exhaust valve plate 15 be floating type like this, reduced the stress of distortion, the possibility of exhaust valve plate 15 fractures reduces greatly, and therefore the minimizing of off-load valve port axial dimension can not increase clearance volume, off-load return spring 11 adopts conical helical spring, the air-flow path that clearance increases when reducing off-load to greatest extent.
