Abstract
A rotary screw compressor with a lift valve comprising a valve member having two rigidly connected cylindrical sections of different diameter. The valve member is displaceably mounted in a valve housing extending through the high pressure end wall of the compressor. The valve housing sealingly surrounds each of the cylindrical sections. The section of the smaller diameter and the corresponding part of the valve housing face the working space of the machine. The lift valve is mounted such that the direction of motion of the valve member is inclined relative to the axial direction of the compressor.
