Abstract
The utility model relates to the technical field of a piston type automotive air conditioning compressor, and in particular relates to an improved cylinder cover pad. The improved cylinder cover pad comprises a cylinder cover pad body. The improved cylinder cover pad is characterized in that a quincunx limiting plate is arranged in the centre of the cylinder cover pad, and multiple limiting grooves are arranged on the limiting plate. Compared with the prior art, a central hole is not formed in the conventional cylinder cover pad, bolts and nuts are canceled, and the limiting grooves are added, thereby reducing the cost, and reducing the internal leakage to meet the requirements of clients.
Description
Technical field
The utility model relates to the piston-type automobile air-conditioning compressor technical field, specifically a kind of improved cylinder cover cushion.
Background technique
Cylinder cover cushion is component in the piston compressor, and cylinder cover cushion plays the effect of sealing, but because traditional cylinder cover cushion manufacture cost is high, can not reach client's demand.
Summary of the invention
The utility model is cancelled center hole for overcoming the deficiencies in the prior art at traditional cylinder cover cushion, and the cancellation screw and nut increases restraining groove, so just can reduce cost, and leaks in reducing, and reaches client's demand.
For achieving the above object, design a kind of improved cylinder cover cushion, comprise the cylinder cover cushion body, it is characterized in that: be provided with quincunx limiting board in cylinder cover cushion central authorities, be laid with some restraining grooves on the limiting board.
Described restraining groove is provided with 7 at least.
The utility model is compared with prior art, cancels center hole at traditional cylinder cover cushion, and the cancellation screw and nut increases restraining groove, so just can reduce cost, and leaks in reducing, and reaches client's demand.
