Title:
ROTARY COMPRESSOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/004993
Kind Code:
A1
Abstract:
A rotary compressor (102) is provided with a shaft (4), a cylinder (5), a piston (8), a first vane (32) and a second vane (33). The first vane (32) partitions the space between the cylinder (5) and the piston (8) along the circumferential direction of the piston (8). The second vane (33) further partitions the space partitioned by the first vane (32), along the circumferential direction of the piston (8), so that a first compression chamber (25) and a second compression chamber (26) having a smaller volume than the first compression chamber (25) are formed within the cylinder (5). The piston (8) and the second vane (33) are integrated or are joined together.
