Claims

[Scope of utility model registration request]

A roller is provided eccentrically rotatably inside a cylinder in which a blade chamber is formed as a compartment, and a roller is provided in the blade chamber,
A rotary compressor configured by reciprocatingly disposed blades that are urged to come into contact with the outer peripheral surface of the roller;
A refrigeration cycle configured by sequentially connecting a first heat exchanger, a pressure reducing device, and a second heat exchanger to the suction port and discharge port of the rotary compressor; A communication path is provided between the heat exchanger No. 2 and the blade chamber and guides a part of the refrigerant in the refrigeration cycle to the blade chamber, and the blade chamber rises as the blade moves toward the rear side. A refrigeration cycle device characterized by comprising a buffer means for buffering pressure.
