Abstract

1386890 Rotary compressors; separating lubricant STAL REFRIGERATION AB 19 Dec 1972 [23 Dec 1971] 58560/72 Headings F1F and F1N A refrigerant-compressing unit includes a compressor 2, which may be of the meshing-screw type, an oil container 3 housing an oil and refrigerant separator 4 and closed at its upper end by a portion 10 of the compressor casing comprising refrigerant inlet and outlet ports 8,9 and an electric motor 1 driving the compressor through a coupling 14. The separator 4 is in the path of the refrigerant-and-oil mixture issuing from the compressor. Secondary separators 5 remove any residual oil from the refrigerant rising to the port 9. An oil pool 6 is cooled by refrigerant injected through a temperature controlled valve 13. The pressure of the refrigerant above the pool 6 returns the oil to the compressor through a filter 7. Alternatively, the pool is cooled by a refrigerating coil therein.
