Abstract

PURPOSE:To reduce noise by providing a cylinder with a small diameter hole opened to a discharge notched portion and a large diameter hole communicated with the small diameter hole. CONSTITUTION:A small diameter hole 16 opened to a discharge notched portion 12 and a large diameter hole 17 communicated with the small diameter hole 16 are provided to a cylinder 6 to constitute a pressure attenuator 15. The pressure of refrigerant gas shut in the compression chamber 10 of the cylinder 6 is thereby raised, and, at that time, a pressure pulsating component generated is absorbed into the small diameter hole 16 and the large diameter hole 17 and damped. The pressure pulsation in the cylinder 6 can therefore be damped, resulting in noise reduction.
