ABSTRACT:
A scroll machine has an intermediate pressure cavity which is operable to open and close a leakage path between the discharge zone and the suction zone of the scroll machine. The leakage path is closed when intermediate pressurized fluid is supplied to the cavity and the leakage path is open when the cavity is open to the suction zone of the compressor. A valve which can be mechanical or electrical is used to open and close a passageway extending between the cavity and the suction zone of the machine.
