HIGH PRESSURE COMPRESSOR AND REFRIGERATING MACHINE HAVING A HIGH PRESSURE COMPRESSOR

A high pressure compressor and a refrigerating cycle device including a high pressure compressor are provided. The high pressure compressor may include a casing in which refrigerant discharged from a compression unit or device is filled into an inner space provided with a drive motor; a suction pipe directly connected to a suction port of the compression unit; a discharge pipe in communication with an inner space of the casing; a first valve provided at the discharge pipe or the suction pipe to control a flow the discharged refrigerant from a high pressure side to a low pressure side when the drive motor is stopped; a bypass pipe connected between a discharge side and a suction side based on the compression device; and a second valve provided at the bypass pipe to move refrigerant at the high pressure side to the low pressure side through the bypass pipe, thereby allowing a differential pressure operation to continue when the compressor is stopped, to enhance energy efficiency as well as allowing a suction pressure and a discharge pressure to rapidly reach an equilibrium pressure during restart so as to efficiently perform the restart.
