Rotary helical screw-type compressor having a thermally separated oil supply container

摘要

A screw compressor has a gear housing (1) from one side of which the rotor housing (3) containing the two screw rotors freely projecting outward. An oil supply container (7) is also located freely projecting out from the gear housing (1) approximately parallel to the rotor housing (3) and thermally separated from the rotor housing by means of an air gap. A ventilation channel (109) in the rotor housing (3) to vent the rotor shaft seals opens up to one point in the rotor housing that is protected against direct access by the oil supply container (7) mounted in front of it as well as by additional shoulders (111).
