IPC: F04D29/06
Filed: 1992-12-25
Abstract: PURPOSE: To prevent oil from entering into a motor easing from a drive device upon stop of an operation. CONSTITUTION: Since a tapered piston 81 reciprocally mounted on a shaft 79 increases the flow of refrigerant passing through openings 91 and 92 under increased pressure from within the motor casing of a centrifugal compressor, the piston moves toward the flow of the refrigerant against a compression spring 82 as a biasing means. Thus, the pressure drop of a back pressure valve 46 is regulated to a prescribed level. The shaft 79 has an extending part protruding toward the motor casing through the tapered piston 81. When the operation of the compressor stops and the pressure in the back pressure valve 46 is larger than the pressure of the motor easing, the tapered piston 81 passes through the inlet opening 91 and moves to the extending part of the shaft 79 to restrict the flow of the referigerant into the motor casing.
