Abstract

The invention provides a compressor which comprises a screw, a star wheel and a screw seal housing, wherein a star wheel groove is formed in the screw seal housing; a star wheel side seal surface is formed between the star wheel groove and the star wheel; the compressor further comprises an exhaust opening formed in one side of the star wheel groove; one top point of the exhaust opening is arranged on the star wheel side seal surface, and arranged at the tooth outlet end of the star wheel groove. According to the invention, the top point of the exhaust opening is arranged on the star wheel seal surface to enable high pressure gas to be discharged from the exhaust opening completely, so that the secondary compression of the high pressure gas is prevented, and further the problems that power loss is caused, noise is produced, vibration is increased, and the like are solved.

Description

technical field [0001] The present invention relates to the field of compressors, more specifically, to a compressor. Background technique [0002] Such as Figure 1 to Figure 2 As shown, the compressor in the prior art mainly includes a screw 1, a star wheel 2 and a screw sealing casing 3, the screw sealing casing 3 is provided with a star wheel groove, and a star wheel side seal is formed between the star wheel groove and the star wheel 2 On the surface 5, an exhaust port 4 is arranged on the screw sealing shell 3, and the compressed gas is finally discharged from the exhaust port 4. [0003] However, the edge of the exhaust port 4 in the prior art that is closest to the star wheel side sealing surface 5 is parallel to the star wheel side sealing surface 5, and there is a certain distance between the two, so that during the exhaust process, the exhaust The side of the gas port 4 closest to the star wheel side sealing surface 5, the gas in the closed volume formed between ...
