The utility model discloses cushion chamber part is located the casing inboard, and part is located the casing outside.

The gas outlet setting is inboard at the casing, is connected with the outer trachea of arranging of casing through section connecting pipes.

The gas outlet sets up in the casing outside, the outer trachea of arranging of compressor is through section pipe connection to gas outlet.

The cushion chamber is through welding, pasting or riveting mode and casing fixed connection.

The utility model provides kinds of compressors, including above-mentioned casing, be equipped with motor and mechanical motion part in the casing, mechanical motion part is equipped with the gas vent, the gas vent of mechanical motion part is connected to interior exhaust pipe end, and end is connected in addition the air inlet of cushion chamber.

Inboard interval fixed distance of L shape baffle is equipped with the parallel longitudinal baffle of , the scavenge port is formed by the clearance between longitudinal baffle and the L shape baffle.

The utility model discloses the theory of operation is as follows, the utility model discloses on the basis of not changing casing basic form, on the noise reduction effect of original design, increase cushion chambers that improve the exhaust pulsation on the casing surface, the cushion chamber size is confirmed according to shell structure and product design requirement, cushion chamber mounted position can be installed in the position that the casing allows as required, increase behind the exhaust cushion chamber, the high-pressure exhaust that the compressor produced firstly gets into the cushion chamber and obtains the buffering to reduced the exhaust pulsation, reduced the exhaust noise, the exhaust rethread outer blast pipe discharge casing after the buffering gets into the refrigerating system circulation.

Compared with the prior art, the utility model has the advantages of 1, optimize compressor exhaust pulsation, reduce the exhaust noise, thereby reduce compressor complete machine noise, surge chamber part is arranged in the casing outside, can increase the volume as far as possible according to actual installation space, thereby improve the noise reduction effect, 2, compare in prior art with the mode that the surge chamber sets up outside through blast pipe and casing fixed connection of casing, the intensity has been improved, difficult emergence is out of shape or is damaged, 3, the exhaust of high temperature gets into the surge chamber at first and exchanges with external low temperature environment heat, thereby reduce the influence of high temperature exhaust to the low temperature gas heating in the casing, make the internal gas density increase of casing, the efficiency of breathing in of compressor has been improved, thereby improve the compressor efficiency.
