Abstract
A positive displacement compressor or pump of the scroll type including first and second scroll plates having convoluted interfitting vanes. The flanks of the vanes on scroll plates are interfitting and in sealing contact with one another and the tips of the vanes in sealing contact with the other plate. One of the plates has a generally central port and the assemblage is provided with a peripheral port at the interface of the plates. A motor and linkage are provided to cause the plates to undergo orbital movement relative to each other and a selectively operable mechanism is operable to separate the plates to break sealing contact and thereby unload the compressor or pump.
