Title:
ROTARY COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2005/113985
Kind Code:
A1
Abstract:
A rotary compressor in which a piston (22) is placed in cylinder chambers (C1, C2) of a cylinder (21), which is constructed such that the cylinder (21) and the piston (22) perform relative eccentric rotation motion, and which has a compression mechanism (20) where the cylinder chambers (C1, C2) are partitioned into high-pressure chambers and low-pressure chambers by a blade (23). To prevent occurrence of vibration and noise caused by a pressure pulsation produced in a suction stroke, a low-pressure space (S1) communicating with the suction side of the compression mechanism (20) and a high-pressure space (S2) communicating with the discharge side of the compression mechanism (20) are formed in a casing (10), and a suction tube (14) communicating with the low-pressure space (S1) and a discharge tube (15) communicating with the high-pressure space (S2) are formed in the casing (10).
