Document Type and Number:
WIPO Patent Application WO/2017/090089
Kind Code:
A1
Abstract:
A rotary compressor (1) comprising a first compression unit (10) and a second compression unit (20) is provided, at the second compression unit (20), with a switching mechanism (31) for switching between a compression operation state in which a second vane (24) abuts against an outer peripheral surface of a second piston (23) and a non-compression operation state in which the second vane (24), having been drawn away from the outer peripheral surface of the second piston (23), is attracted and fixed by a permanent magnet (32). The second compression unit (20) of the rotary compressor (1) is further provided with a second yoke (43) that is arranged further forward than a back surface section (24c) of the second vane (24) so that a third force suctioning the second vane (24) forward acts at a bottom dead center position at which the second vane (24) is moved the farthest forward.
