Abstract
A high pressure compressor may include a casing in which a refrigerant discharged from a compression device is filled into an inner space provided with a drive motor, a suction pipe directly connected to a suction port of the compression device, a discharge pipe in communication with the inner space of the casing, a first valve provided at the discharge pipe or the suction pipe to control a flow of 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 the 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.
