Abstract

A rotary compressor () and a refrigeration cycle device () having same are provided. The rotary compressor comprises: a liquid reservoir (), a first direction control assembly (), and a compression mechanism. The compression mechanism comprises two cylinders and two gas injection holes, in which a sliding vane of one cylinder is pressed against an outer circumferential wall of a piston in the cylinder and a gas injection hole is used for injecting a refrigerant to the cylinder, while the sliding vane of the other cylinder is optionally in contact with or separate from the piston in the cylinder, the other gas injection hole is used for unidirectionally injecting the refrigerant into the cylinder; a first valve port () of the first direction control assembly () is connected to the gas suction port of the other cylinder, a second valve port () thereof is connected to liquid reservoir (), a third valve port () thereof is in communication with the exhaust hole, and the second valve port () and the third port () are optionally in communication with the first valve port ().
