Abstract: The present invention provides the art with a scroll machine which has a plurality of built-in volume ratios along with their respective design pressure ratios. The incorporation of more than one built-in volume ratio allows a single compressor to be optimized for more than one operating condition. The operating envelope for the compressor will determine which of the various built-in volume ratios is going to be selected. Each volume ratio includes a discharge passage extending between one of the pockets of the scroll machine and the discharge chamber. All but the highest volume ration utilize a valve controlling the flow through the discharge passage.

Abstract: The present invention provides the art with a scroll machine which has a plurality of built-in volume ratios along with their respective design pressure ratios and comprising a shell having an end cap, said end cap defining a barrier between a chamber defined by said shell and an environment outside said scroll machine; a first scroll member disposed within said chamber having a first spiral wrap projecting outwardly from a first end plate; a second scroll member disposed within said chamber having a second spiral wrap projecting outwardly from second end plate, said second scroll wrap being interleaved with said first spiral wrap; a drive member for causing said spiral wraps to orbit with respect to one another whereby said spiral wraps create pockets of progressively changing volume between a suction pressure zone at a suction pressure and a discharge pressure zone at a discharge pressure; a first annular seal engaging said end cap and said first scroll member, said first annular seal being disposed around a hole extending through said end cap.
