Compressor

Abstract

The present invention relates to a compressor, which has a bolt-cooling part formed between a suction chamber and a bolt fastening hole formed at a position, where the suction chamber and a discharge chamber of a housing are partitioned from each other, for allowing for a flow of refrigerant toward the bolt fastening hole to reduce an influence of temperature of discharged refrigerant, thereby preventing loosening of a bolt due to a thermal expansion, and improving durability.

1 . A compressor comprising:
 front and rear housings, each housing having a plurality of bolt fastening holes formed in a circumferential direction therein, a suction chamber and a discharge chamber partitioned from each other by partition walls formed therebetween, and a bolt-cooling part formed between the suction chamber and the bolt fastening hole formed at the partition wall where the suction chamber and the discharge chamber are partitioned from each other to allow for a flow of refrigerant toward the bolt fastening hole;   front and rear cylinder blocks mounted between the front housing and the rear housing; and   a plurality of pistons mounted inside cylinder bores of the front and rear cylinder blocks for performing a reciprocating motion in cooperation with a rotating motion of a swash plate rotating in a swash plate chamber.   
   
   
       2 . The compressor according to  claim 1 , wherein the bolt-cooling part is a communication passageway formed on the partition wall on which the bolt fastening hole is formed for fluidically communicating the suction chamber and the bolt fastening hole with each other.
