Beschreibung
Zusammenfassung:	An oil flooded screw compressor including suction, rotor, and discharge sections having suction, intermediate pressure, and discharge ports, respectively, and an oil sump. The discharge section includes radially spaced internal and external housings, with the internal housing receiving an oil-gas stream from the rotor section. A filter is disposed to surround the internal housing, with the filter including a cylindrical, foraminate body portion, an end wall, and a filter pad against the end wall. The oil-gas stream from the rotor section exits the inner housing, via an opening which forms part of a first stage of oil removal. The oil-gas stream strikes the filter pad, removing oil as the oil-gas stream is forced to turn 90 degrees to exit the filter through the foraminate body portion, which also removes oil. The filter functions as second and third stages of oil removal.
