Abstract
In a refrigerant compressor, a driving shaft is rotatably supported within a compressor housing by a bearing on a suction side. A trigger valve is provided in a passageway communicating a discharge pressure chamber with the bearing on the suction side. When pressure within the discharge pressure chamber is lower than a predetermined value, the trigger valve opens the passageway to permit gaseous refrigerant of high temperature within the discharge pressure chamber to be supplied to the bearing on the suction side.
