Title:
GAS COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2015/104930
Kind Code:
A1
Abstract:
A gas compressor (1) equipped with: a block part (19) in the interior of which a cylinder chamber (32) is formed; a rotor (23) rotatably housed in the cylinder chamber (32); and multiple vanes (25) provided on the outer circumferential part of the rotor (23) so as to be capable of extending and retracting, with intervals between the vanes in the circumferential direction. The block part (19) has pressure supply parts that supply pressure to a back-pressure space (77) of the vanes (25). These pressure supply parts include intermediate pressure supply parts (51, 67), which communicate with the back-pressure space (77) from the intake stroke to the compression stroke of the compression chamber (33), first high-pressure supply parts (53, 69), which communicate with the back-pressure space (77) from the compression stroke to the discharge stroke of the compression chamber (33), and a second high-pressure supply part (72), which is formed separately from the first high-pressure supply part (69), between the intermediate pressure supply part (57) and the first high-pressure supply part (69), and communicates with the back-pressure space (77) in the middle of the compression stroke of the compression chamber (33).
