Rotary compressor with low pressure space surrounding outer peripheral face of compression mechanism and discharge passage passing through housing

摘要

A rotary compressor includes a compression mechanism in which a piston is disposed inside a cylinder chamber of a cylinder. The cylinder and the piston eccentrically rotate relative to each other. The cylinder chamber is sectioned into a high pressure chamber and a low pressure chamber in order to prevent production of vibration and noises due to pressure pulsation caused in a suction process. A low pressure space communicating with a suction side of the compression mechanism and a high pressure space communicating with a discharge side of the compression mechanism are formed in the casing. A suction pipe communicating with the high pressure space and a discharge pipe communicating with the high pressure space are disposed in the casing.
