Rotary screw technology uses a displacement principle where the screw compression element main parts comprise male and female rotors that move towards each other while the volume between them and the housing decreases.
The pressure ratio of a screw is dependent on the length and profile of the screw and of the form of the discharge port. The screw element is not equipped with any valves and there are no mechanical forces to create any imbalance. It can therefore work at high shaft speed and combine a large flow rate with small exterior dimensions.
