Abstract
A positive displacement compressor or pump of the scroll type including first and second scroll plates (10, 12) having convoluted interfitting vanes (16). The flanks (18) of the vanes (16) on scroll plates (14) are interfitting and in sealing contact (20) with one another and the tips (22) of the vanes (16) in sealing contact with the other plate (14). One of the plates (14) has a generally central port and the assemblage is provided with a peripheral port (39) at the interface of the plates (14). A motor (35) and linkage (38) are provided to cause the plates to undergo orbital movement relative to each other and a selectively operable mechanism (40, 44, 46, 48; 62, 66, 76) is operable to separate the plates (14) to break sealing contact and thereby unload the compressor or pump.
