Abstract

1,062,687. Bearings. LENNOX INDUSTRIES Inc. Sept. 9, 1965 [Sept. 28, 1964], No. 38558/65. Heading F2A. [Also in Division F1N] In a hermetically sealed refringement compressor, Fig. 1 (not shown), having pistons (28) reciprocated by a normally vertical crank-shaft journalled in bearings (78, 80) lubricated by oil pumped from a sump (90) through a longitudinal passage (86) to radial passages (94, 95) the oil which flows upwardly in the upper bearing is returned to the sump through passages (97, 98, 99) and is thereby prevented from escaping into the suction gas flowing past the motor (69) driving the crank-shaft. To facilitate the return of the oil through the passages (97), a groove (96), Fig. 2 (not shown), formed in the bearing (78) or in the shaft (30) is provided in alignment with the passage (97). In a modification, Fig. 4 (not shown), oil is positively prevented from escaping from the upper bearing by a seal (108), and a slinger ring (110) disposed between the bearing and the seal (108) throws any oil attempting to escape into a passage (112) for return to the sump via an annular space (84) and the passages (97, 98, 99). In a further modification, Fig. 6 (not shown), a suction pressure is developed in the passages (97, 98) by oil drawn from the sump through a passage (121) passing around a nozzle (120) connected to the passage (98) and disposed in the passage (99).
