Abstract

1464239 Rotary positive-displacement fluidmachines ATLAS COPCO AB 19 June 1975 [24 June 1974] 26099/75 Heading F1F In an oil lubricated axial flow screw compressor, oil which is sprayed on two gears 11, 14 is driven by the pressure in the gear's casing through ducts 19 and 20 to a lower pressure part of the compressor, the interior of the gear casing being connected by a duct 16 to an intermediate pressure region in the compressor's barrel. The compressor's discharge enters a receiver 24 which serves as an oil reservoir and oil is driven by the discharge pressure along conduit 26 to holes 28 and into the barrel to lubricate the rotors and cool the working fluid.
