Claim 0:
1. A compressor for a vapor compression system, comprising:
a housing;
a first rotor and a second rotor disposed within the housing, wherein the first rotor is configured to rotate about a first axis of the housing and the second rotor is configured to rotate about a second axis of the housing, wherein the first rotor and the second rotor are configured to engage with one another such that rotation of the first rotor and the second rotor pressurizes a vapor within the housing; and
an end plate coupled to a discharge end of the housing, wherein the end plate comprises:
an inner surface;
an opening extending through the inner surface and configured to receive a shaft of the first rotor;
a variable opening extending through the inner surface and configured to discharge a flow of the vapor from the housing;
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 and the second movable member is configured to slide along the second groove to increase or decrease a cross-sectional area of the variable opening to adjust the flow of the vapor, the first groove and the second groove each define a respective first stop and a respective second stop, the first stop of the first groove and the second stop of the first groove are configured to limit movement of the first movable member within the first groove via contact with the first movable member, and the first stop of the second groove and the second stop of the second groove are configured to limit movement of the second movable member within the second groove via contact with the second movable member.
