Beschreibung
Zusammenfassung:	A screw machine, in particular screw compressor, includes a machine housing, screw rotors forming a rotor pair which is mounted in the machine housing, an oil supply system via which bearings and seals of the screw rotors can be supplied with oil for lubricating and/or cooling, wherein the oil supply system has an oil supply and oil feeds, wherein the oil supply system includes a pressure sensor, which detects a pressure in the oil discharge or oil return or a pressure difference between the pressure in the oil discharge or oil return and a pressure in the oil feeds, the oil supply system furthermore includes a control device, which open-loop or closed-loop controls the pressure in the oil feed or the pressure difference dependent on the measurement signal of the pressure sensor.
