Compressor

Abstract

Provided is a compressor with which it is possible to minimize an increase in pressure of a refrigerant in a space formed between a discharge valve and a retainer. The compressor comprises a fixed end plate ( 31 a ) having formed therein a discharge port ( 37 ) through which a compression chamber and a discharge chamber ( 35 ) communicate, a discharge valve ( 70 ) that opens and closes a discharge opening ( 37 a ) positioned on the discharge chamber ( 35 ) side of the discharge port ( 37 ), and a retainer ( 80 ) that regulates the amount of flexure of the discharge valve ( 70 ), the retainer ( 80 ) having a through-hole ( 81 ) passing through the upper and lower surfaces of the retainer ( 80 ), and the through-hole ( 81 ) being formed directly above the discharge opening ( 37 a ) and directly above the portion of the fixed end plate ( 31 a ) where the discharge opening ( 37 a ) is not formed.

1 . A compressor comprising:
 a partition wall in which a discharge port allowing a compression chamber and a discharge chamber to communicate with each other is formed;   a discharge valve that opens and closes a discharge opening on a discharge chamber side of the discharge port, which is located on the discharge chamber side; and   a retainer that regulates an amount of deflection of the discharge valve,   wherein the retainer includes a through-hole that penetrates an upper surface and a lower surface of the retainer, and   the through-hole is formed directly above the discharge opening and directly above a portion of the partition wall in which the discharge opening is not formed.   
     
     
         2 . The compressor according to  claim 1 ,
 wherein the retainer has a tongue-like shape that extends from a base end fixed to the partition wall toward a tip, and   the through-hole is integrally formed from a position directly above the discharge opening toward the base end along an extending direction of the retainer.   
     
     
         3 . The compressor according to  claim 2 ,
 wherein the through-hole is integrally formed at least from the position directly above the discharge opening to an intermediate position between the tip and the base end.   
     
     
         4 . The compressor according to  claim 2 ,
 wherein the through-hole has a notch shape that extends from an edge of the tip of the retainer toward a base end side of the retainer.   
     
     
         5 . The compressor according to  claim 3 ,
 wherein the through-hole has a notch shape that extends from an edge of the tip of the retainer toward a base end side of the retainer.
