Abstract
212,269. Hill Engineering Co., Inc., (Assignees of Hill, M. F.). April 10, 1922, [Convention date]. Force-feed lubricating.-A rotary compressor of the type comprising an annular lobed rotor 4 and an eccentric inner pinion rotor 7 with one lobe less is provided with means for circulating oil for sealing and lubricating. Oil is supplied under the delivery pressure of the gas from a reservoir 28 through a pipe 29 with a controlling valve 54 to a port 32 in the side of the casing to lubricate and seal the rotating elements, excess being returned with the gas through discharge in the pinion rotor and a discharge passage in the boss 16 on which the pinion is mounted to a separator 51. The presence of the oil tends to make the compression isothermal. A pipe 53 also supplies oil under pressure to a circular groove 43 at the other side of the casing to prevent leakage of gas such as sulphur dioxide &c. used in refrigerating systems. An inner circular groove 14 is connected to the compressor inlet to prevent leakage of oil through the motor shaft bearing. A packing ring 50 on the boss 16 prevents communication between the inlet and discharge passages of the pinion rotor. The oil may be led to an external cooler through which air is drawn by a fan on the other end of the motor shaft. Specification 195,934 is referred to.
