Abstract
Screw compressors and screw compressor systems are disclosed in which the compressors include an oil injection port that injects oil into the compression chamber during a compression cycle. The oil injection port is located in an outer wall of the cylindrical bore within the compressor housing in which the main rotor is rotationally mounted. The oil injection port is located and configured to inject oil into the compression chamber during a time period such that the average pressure ratio of the pressure of the compression gasses within the compression chamber relative to the suction pressure during the time period is reduced as compared to standard compressors. The design of the oil injection port allows screw compressor systems to not include an oil pump.
