Claim 10:
11. A vapor compression system, comprising:
a compressor including a first rotor configured to rotate about a first axis and a second rotor configured to rotate about a second axis, wherein the first rotor and the second rotor are configured to engage with one another to compress a refrigerant within a housing of the compressor; and
an end plate coupled to the housing, wherein the end plate comprises:
an inner surface;
a first opening extending through the inner surface and configured to receive a first shaft of the first rotor;
a second opening extending through the inner surface and configured to receive a second shaft of the second rotor, wherein the inner surface circumferentially surrounds the first opening and the second opening independently of one another;
a variable opening extending through the inner surface and configured to discharge a flow of the refrigerant from the housing to circulate the refrigerant through the vapor compression system;
a first groove recessed in the inner surface;
a second groove recessed in the inner surface; and
a first movable member disposed within the first groove and a second movable member disposed within the second groove, wherein the first movable member is configured to slide along the first groove, the first movable member extends only partially about a first circumference of the first opening, the second movable member is configured to slide along the second groove to adjust a cross-sectional area of the variable opening, and the second movable member extends only partially about a second circumference of the second opening.
