Problems solved by technology

[0009] However, due to the complicated refrigerant passage in the inner space of the suction muffler, the flow resistance of the sucked refrigerant is increased, thereby seriously increasing the suction loss of the refrigerant
[0010] In addition, since the outer wall of the resonant chamber S containing the refrigerant is in contact with the inner space of the compressor chamber, the internal heat of the compressor chamber will be easily transferred to the refrigerant, thereby further increasing the refrigerant's suction loss

Abstract

The present invention discloses a suction muffler structure for compressor, comprising a chamber, which has an inlet connecting to inner space of the compressor chamber and an outlet connecting to pump side of the cylinder; a pipe passage, which is arranged inside of the chamber for connecting the inlet and outlet directly. The pump muffler improves suction quantity of cryogen sucked into the cylinder, and over heat of the cryogen is prevented, such that performance of the compressor is improved.

Description

technical field [0001] The present invention relates to a suction muffler for a compressor, and more particularly, to a suction muffler for a compressor which can increase the suction amount of refrigerant and prevent overheating of the refrigerant . Background technique [0002] Generally, a suction muffler is installed on a reciprocating compressor to reduce valve noise, flow noise, and micro-pressure pulsations generated when refrigerant is sucked into the compressor unit. The suction muffler for the compressor is installed on the suction side of the compressor unit and connected to the inner space of the compressor room for guiding the refrigerant filled in the inner space into the compressor unit. Usually, a thin neck part and a wide distance part are installed in the suction muffler to form a complex refrigerant passage. [0003] figure 1 is an exploded perspective view showing a conventional suction muffler applied to a reciprocating compressor. figure 2 is a sec...
