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.

Compressor and refrigeration cycle device having the same

A rotary compressor includes a compression device including a compression space to accommodate a refrigerant introduced through an inlet, and configured to compress the refrigerant and to discharge the refrigerant to an outlet, a driving device to drive the compression device, a flange member to partition an inner portion of the case into a low-pressure region and a high-pressure region, and a muffler member disposed on a surface of the flange member to form a first space to store oil and a second space. The flange member includes a first hole communicating with the second space to allow the low-pressure region to communicate with the compression space, the muffler member includes a second hole which forms part of a refrigerant flow path, and at least one of the flange member and the muffler member includes a third hole which forms part of an oil flow path.

Rotary compressor and home appliance including the same

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.

Rotary compressor with first and second main suction ports

A horizontal type rotary compressor includes a case including an inlet and an outlet and configured to store oil, a compressor having a compression space in which refrigerant is accommodated, a driver to drive the compressor, a rotating shaft to connect the driver and the compressor, an oil feed pipe disposed at a side of the compressor, a first plate configured to divide the case into a first area for the driver and a second area for the compressor. The first plate including a discharge hole through which compressed refrigerant is discharged from the compressor to the first area. A second plate dividing the case into the second area and a third area in which the oil feed pipe communicates with the outlet, and includes a second hole formed at the upper side to communicate the second and third areas. The first and second plates forming an oil flow path.
