CLOSED LOOP COMPRESSED GAS SYSTEM WITH OIL MIST LUBRICATED SCREW COMPRESSOR ABSTRACT OF THE DISCLOSURE A rotary helical screw compressor for a refriger- ation system employing a condensable refrigerant comprises intermeshed rotors mounted for rotation by way of anti-friction bearings, within a hermetic housing. A lubricating oil miscible in liquid refrig- erant is supplied to the compressor in a mass ratio of between .25 and 12%, by weight of solution. Vaporized working fluid at discharge pressure and bearing oil mist is permitted to step through the anti-friction bearings in closed loops, from the discharge side of the machine towards the suction side, for efective lubrication. Thus, the refrigeration system is oil pump free, oil sump free, and oil filter free. liquid refrigerant oil solution may be bled from the con- denser and injected into the compression chamber defined partially by the intermeshed rotors at a point in the compression process where the compression chamber is cut off from suction and discharge sides of the compressor, for cooling the rotors.
