Abstract

1,084,279. Refrigerating. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Dec. 9, 1965 [Dec. 16, 1964], No. 52288/65. Heading F4H. A device for producing high refrigerant velocities in vertical piping of a refrigeration system to ensure oil return to the compressor when the latter is operating at reduced load comprises an outer tube 19, 22 having an inlet 21 for refrigerant vapour and a closed lower end 23, and an inner tube 24 the bottom of which is spaced from the bottom of tube 22, the arrangement being such that at reduced loads entrained oil separated out from the refrigerant seals the lower end of tube 24 and refrigerant is constrained to flow at high velocity through the annular gap 29 between the tubes. At high loads the refrigerant pressure is sufficient to remove some or all of the separated oil so that refrigerant may flow through both tubes. The tubes are maintained in concentric relaitionship by pins 26, 27. Two such devices may be provided in a single refrigeration system (Fig. 1, not shown).
