Abstract

1389973 Screw compressors FORD MOTOR CO Ltd 13 March 1973 [29 March 1972] 12034/73 Heading F1F An externally-meshing helical screw compressor, for instance of the Lysholm type, comprises a plurality of radially extending lubrication metering chambers 34, 36, 38 in one axial end of one of the rotors, preferably the female one 30, the radially inner portions of the chambers 34, 36, 38 being arranged to successively communicate with a lubricating oil inlet chamber 40 in the adjacent end wall of the compressor housing, chamber 40 being in communication with an oil supply passage 42, and the radially outer portions of chambers 34, 36, 38 being arranged to successively register with a lubricating oil discharge chamber 44 which communicates with both rotor chambers 28,32, whereby metered quantities of fluid are discharged into the rotor chambers 28,32 in dependence on the speed of the compressor. When used in a vehicle air conditioning system, the male rotor is the drive rotor being driven by a pulley 12 on a shaft 54 coupled to the male rotor shaft 46 by an electromagnetic clutch 48,50,52. FREON is used as a coolant.
