Abstract
An improved discharge port of a rotary screw compressor is described. A discharge port of a screw compressor generally includes a restrictive portion to help prevent a leakage of working fluid back to a suction side of the compressor. The improved discharge port is configured to have a restrictive portion with a reduced size compared to a restrictive portion of a conventional discharge port, resulting in an enlarged opening of the discharge port compared to a conventional discharge port. The improved discharge port can help discharge the compressed working fluid more quickly than a conventional discharge port, reducing and/or avoiding over-compression of the working fluid. The efficiency gained due to the enlargement of the opening may be more than the efficiency loss due to leakage of working fluid back to the suction side, resulting in a net efficiency gain of the compressor.
