Abstract

1,212,015. Rotary positive-displacement compressors. SVENSKA ROTOR MASKINER A. B. April 25, 1968 [May 3, 1967], No. 20454/67. Heading F1F. A rotary compressor has parallel bores 16, 18 containing intermeshing male and female screwrotors 26, 28 with shafts in chambers 48, 52, 60, 64 wherein oil leaking from bearings for the shafts is collected and thence drawn through openings 74, 76, 78 into the bore 16 and a channel 20 for lowpressure working-fluid. The opening 74 is situated in the bore 16 such that it can communicate with the channel 20 through the grooves of the female rotor and is therefore in a region of comparitively low-pressure. Bearings 50, 62 receive pressurized oil through annular grooves 68, 70 so as to minimize leakage of working fluid from the bores. Oil leaking from the bores lubricates bearings 46, 58. The oil issuing from the opening 74 lubricates and seals the rotors, additional oil being fed to the bores through nozzles (84), Fig. 2 (not shown). The opening 74 may be replaced by a similar opening at the high-pressure end of the bore 16, Fig.4 (not shown). In a second embodiment, Fig. 3, oil is delivered to plain bearings 86, 90, 96, 104 and a seal 112 through channels 108, 110, 122, thrust bearings 92, 106 being lubricated by oil leaking from the adjacent plain bearings. Surplus oil flows into the bore 16 through an opening 118. The channel 122 receives pressurized oil through a chamber 102 for a thrust-balancing piston 100.
