Abstract
A variable size is provided for a discharge port in a scroll compressor. The variable size is movable dependent on conditions within the scroll compressor to achieve a desired pressure ratio based upon operational conditions in the compressor or an associated refrigerant cycle. In one embodiment a plunger moves axially to increase or decrease the size of a discharge port. In a second embodiment, the plunger rotates about an axis and has a groove that is selectively aligned with the port to increase or decrease the effective size of the port.
