Title:
ROTARY COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2003/083308
Kind Code:
A1
Abstract:
A rotary compressor, wherein a peripheral groove (42) allowing the contraction of a casing (10) at a welded position between the shell part (11) and the end plate (12) of the casing (10) is provided in the outer peripheral surface (40) of a partition member (23) fixed to the casing (10) so as to divide the inside of the casing (10) into a high-pressure space and a low-pressure space so that the partition member (23) can be tightened strongly by utilizing the contraction thereof, whereby a sealability between the high-pressure space and the low-pressure space in the casing (10) can be increased, and the lowering of workability at the time of assembly and an increase in cost can also be prevented.
