摘要

The unit has screw rotors arranged on a body, and a bypass channel provided with a fluid flow control valve device that is connected with a pressure tank. The tank is arranged on downstream behind of a pressure chamber (9). The controlled bypass channel is connected with an inlet port (7) at a compressor housing. The inlet port is arranged in relation to an outlet (5) so that the inlet port is connected as the outlet and is connected with a V-shaped working chamber (3) that is formed by tooth spaces of rotors.
