Title:
ROTARY COMPRESSOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/004992
Kind Code:
A1
Abstract:
A rotary compressor (102) comprises a shaft (4), a cylinder (5), a piston (8), a first vane (32), a second vane (33), a first suction hole (19), and a second suction hole (20). 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 first suction hole (19) guides operating fluid into the first compression chamber (25). The second suction hole (20) guides operating fluid into the second compression chamber (26). A suction check valve (50) is provided in the second suction hole (20).
