Abstract

A high pressure compressor according to the present disclosure and a refrigerating cycle device to which the high pressure compressor is applied may include a casing having a sealed inner space; drive motor provided in the inner space of the casing; a compression unit provided in the inner space of the casing, and provided with a compression space for compressing refrigerant, and provided with a suction port for guiding refrigerant into the compression space, and provided with a discharge port for guiding refrigerant compressed in the compression space into the inner space of the casing a discharge valve provided in the compression unit to selectively open or close the discharge port according to a difference between a pressure of the inner space of the casing and a pressure of the compression space of the compression unit; a first valve configured to suppress refrigerant discharged from the inner space of the casing from flowing backward into the inner space of the casing; a bypass pipe connected between a discharge side and a suction side of the compression unit based on the compression unit; and a second valve provided at the bypass pipe to selectively open or close the bypass pipe.
