Abstract (en)

[origin: WO0053932A1] A rotary helical screw-type compressor has a transmission housing (1) from the one side of which the rotor housing (3) which accommodates the two screw rotors freely projects. An oil reservoir (8) is positioned substantially parallel to the rotor housing (3) and also freely projects from the transmission housing (1). Said oil reservoir is thermally separate from the rotor housing by way of an air gap. A vent channel (109) for venting the rotor shaft seal which is provided in the rotor housing (3) opens into the rotor housing at a location which is protected from direct access by the projecting oil reservoir (7) and the additional projections (111).
