PULSATION SUPPRESSING DEVICE FOR COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To improve a pulsation suppression effect without increasing the weight of a compressor and increasing an interference part. SOLUTION: A mounting part 28 is integrally formed at the end wall 24 of a rear housing 17. A suction chamber 22 and a discharge chamber 23 are partitioned in the rear housing 17. The discharge chamber 23 surrounds the side of the suction chamber 22. An auxiliary chamber 44 is recessed in the suction chamber forming wall surface 241 of the end wall 24 of the rear housing 17 to form the suction chamber 22 in a manner to reach the mounting part 28. Further, the auxiliary chamber 44 is situated, as seen in the axial direction of a rotary shaft 13, in the vicinity of the radial central part of the suction chamber 22.
