摘要： 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.

摘要： The disclosure relates to a compressor having a noise reduction resonator. The compressor includes: a compression part having compression space in which introduced gas is accommodated, and configured to compress and discharge the gas in the compression space; and a gas moving part having an inner wall forming a gas flow path through which the gas discharged from the compression space moves, wherein the gas moving part is provided with a first resonator configured to communicate with the gas flow path on the inner wall forming the gas flow path and having a resonance space depressed upward in a moving direction of the gas. The compressor according to the disclosure may prevent compression efficiency from decreasing and maintain a noise reduction effect for a long period of time by preventing foreign objects or liquids from being accumulated in the resonance space.
