Abstract
A compressor includes a compression chamber forming member, an injection passage, an injection pipe, and a pulsation attenuation space. The compression chamber forming member forms a compression chamber. The injection passage is formed in at least one of the compression chamber forming member and a separate member disposed in a surrounding area and connecting to the compression chamber. The injection pipe supplies refrigerant to the injection passage. The pulsation attenuation space is formed in one of the compression chamber forming member and the separate member disposed in the surrounding area so as to communicate with the injection passage. The pulsation attenuation space attenuates pulsation of refrigerant gas flowing from the injection pipe into the compression chamber.
