Summary: | A pumping system, a shaft for the oil pumping system for hermetic compressors, as well as a compressor including the system and/or the shaft are described. It is foreseen the change in the dimensions and geometry of lubricating oil pumping systems in hermetic compressors which have an oil pump (9) immersed in lubricating oil (2) and associated with a revolving vertical shaft (5) which is rotated by a rotor (6) of an electric motor (7). The oil pumping system also includes the addition of a bent hole (12) in relation to the center line of a revolving vertical shaft (5), apart from a bent lubricating hole in this bent suction tube (12) in the inner portion of the shaft (14). The system further presents changes in the dimensions of the suction hole (9a) and in the position for fixing an oil pump (9), apart from the progressive reduction in the thickness of the wall (16) of the revolving vertical shaft (5). |
