WIPO Patent Application WO/2019/142315
Kind Code:
A1
Abstract:
This rotary compressor comprises, within a hermetic container, an electric motor section, and a compression mechanism section in which a refrigerant is compressed by a drive force transmitted from the electric motor section. The compression mechanism section has: a crankshaft rotationally driven by the electric motor section; a cylinder having a cylinder chamber; a bearing which closes the cylinder chamber; a rolling piston which eccentrically rotates with an eccentric shaft section to compress the refrigerant; a vane which divides the cylinder chamber into a suction chamber and a compression chamber; and a vane spring which urges the front end of the vane so as to press the front end against the outer peripheral surface of the rolling piston. The cylinder has a vane spring groove which lengthens a vane spring containing hole, and the vane spring groove is formed around a vane groove so as to extend from the vane spring containing hole toward the cylinder chamber.
