Screw Compressors ScienceDirect

Thus, the working principle is similar to other positive displacement machines like reciprocating compressors. In an oil-flooded screw compressor, a slide valve is available for capacity control. This slide valve moves axially beneath the rotors and changes the effective rotor length, and also opens an internal recycle volume on the suction side of the compressor.

Pump Wikipedia

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action.Pumps can be classified into three major groups according to the method they use to move the fluid direct lift, displacement, and gravity pumps. Pumps operate by some mechanism (typically reciprocating or rotary), and consume energy to perform mechanical work moving the fluid.
