Problems solved by technology

Correspondingly, a dead zone is created, thereby degrading the compression performance
[0023] Also, in conventional compressors, since the suction path is not formed in the central part of the piston, the gas will be released out of balance

Abstract

A reciprocating compressor includes a piston which reciprocates in a cylinder; a suction valve mounted at an end surface of the piston; a discharging valve assembly that compresses and discharges gas taken into a compression space; and a suction valve fixing member engaged to a frontal surface of the piston to movably receive the suction valve.

Description

Technical field [0001] The present invention relates to a reciprocating compressor, and more particularly to a reciprocating compressor that improves the performance of the compressor by improving the structure of a suction valve for controlling suction and a discharge valve for controlling gas release. Background technique [0002] Generally, a compressor is a device that compresses cooling gas introduced from an evaporator in a low temperature and low pressure state and releases the gas by changing the gas state to high temperature and high pressure. [0003] According to the method of compressing fluid, compressors can be divided into rotary compressors, reciprocating compressors and scroll compressors. [0004] Specifically, a reciprocating compressor sucks and compresses fluid when the piston moves linearly. Such a reciprocating compressor can be divided into the following working methods: the compressor converts the rotational motion of the drive motor into the linear recip...
