Abstract
A hydrostatic machine which includes a housing having an internal space accommodating a rotatably journaled driving mechanism, and wherein the portion of the internal space which is not occupied by the driving mechanism encompasses a drain oil chamber which receives the drain oil inclusive of lubricating oil which is discharged from bearing locations of the hydrostatic machine, and which is connected or port to a tank through at least one drain oil connection of the housing and through a drain oil line. A pump is arranged in the drain oil line which is in a driving or operative connection with the hydrostatic machine, and which pumps off drain oil from the drain oil chamber during the operation of the hydrostatic machine, and possesses an output delivery correlated in such a manner therewith that the drain oil remaining in the drain oil chamber assumes that particular specified level in the lower region of the drain oil chamber, at which at least no splashing losses are encountered due to the rotation of the driving mechanism in the drain oil which exceed the mechanical losses of the hydrostatic machine.
