Abstract: A refrigeration cycle device includes a compressor. The compressor includes a casing, a driving unit disposed in the casing, a compression unit coupled to the driving unit and configured to compress a refrigerant, and a valve configured to control a flow of the refrigerant in the casing. The valve includes a valve chamber including a main flow path in which the refrigerant is to flow, the main flow path including a refrigerant inlet and a refrigerant outlet. The valve also includes a floating body disposed in the valve chamber to open or close the main flow path, and a bypass flow path formed in the valve chamber and which is to be opened or closed by the floating body. When the driving unit is stopped and the bypass flow path is opened by the floating body, the refrigerant is to be detoured to the bypass flow path.

Abstract: This rotary compressor comprises: a casing forming the outer shape; a rolling piston configured to rotate eccentrically in an internal space; a vane configured to contact the rolling piston and divide the internal space into a suction chamber and a compression chamber; and a main suction port connecting the suction chamber to an outside of the cylinder. The rotary compressor also comprises: a cylinder disposed inside the casing; a first flange disposed above the cylinder; and a second flange disposed below the cylinder. The main suction port comprises a sub suction port extending in a direction in which at least one among the first flange and the second flange is disposed, and at least one among the first flange and the second flange has a flow path groove connecting the sub suction port and the suction chamber.
