Abstract
The utility model belongs to the technical field of a piston vehicle air condition compressor, in particular to a cylinder cushion with a convex rib used for a piston vehicle air condition compressor. The cylinder cushion is characterized in that the cylinder cushion is round mechanism; a piston hole, screw holes and a location pin hole are uniformly distributed on the cylinder cushion; and the screw holes outside the cylinder cushion are surrounded by the convex ribs to form seal. Compared with the prior art, the cylinder cushion has a simple structure and strong generality, and improves the seal effect between the valve plate components and the cylinder body.
Description
[technical field]
The utility model belongs to the piston-type automobile air-conditioning compressor technical field, specifically a kind of band convex tendon cylinder liner that is used for piston-type automobile air-conditioning compressor.
[background technique]
Cylinder liner is one of important spare part in the piston-type automobile air-conditioning compressor, the effect of cylinder liner is the gap between sealing bonnet and the valve plate, and the sealing of compressor valve board assembly at present generally to adopt cylinder liner be plain cushion, after long-time the use, its sealing effect is undesirable, and phenomenons such as freezing medium leakage can take place.
[summary of the invention]
The utility model provides a kind of band convex tendon cylinder liner that is used for piston-type automobile air-conditioning compressor in order to overcome the deficiencies in the prior art.
To achieve these goals, the utility model has designed a kind of band convex tendon cylinder liner that is used for piston-type automobile air-conditioning compressor, it is characterized in that: cylinder liner is circular mechanism, even distribution piston hole, screw hole and positioning pin hole on the cylinder liner, the screw hole of cylinder liner cylindrical all adopt convex tendon to surround and form sealing.
The utility model is compared with prior art, and is not only simple in structure, highly versatile, and improved sealing effect between valve board assembly and the cylinder body.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1,1 is cylinder liner; 2 is piston hole; 3 is convex tendon; 4 is positioning pin hole; 5 is screw hole.
[embodiment]
Below in conjunction with accompanying drawing the utility model is described further.
Be illustrated in figure 1 as structural representation of the present utility model, cylinder liner 1 is circular mechanism, and piston hole 2 arranged evenly on cylinder liner, screw hole 5 and positioning pin hole 4, screw hole 5 peripheries of cylinder liner 1 cylindrical adopt convex tendon 3 to surround and form seal ring, the cylindrical that this practicality is compared at cylinder liner with prior art has increased convex tendon, has not only effectively increased sealing area, and has improved the sealing effect between valve board assembly and the cylinder body.Under the square one, sealing effect is better.
