ABSTRACT:
The machine includes at least one set of two cooperating pinions rotating between two mobile bearing flanges which are mobile in translation in cavities provided in a median casing closed on the two opposite sides thereof by anterior and posterior covers. Each of these two bearing flanges is substantially pressure equilibrated by a suitable sealing system arranged between this bearing flange and the adjacent cover. The bearing flanges supporting the pinions are floatingly mounted inside the median casing, and pressure means are provided to press the bearing flanges against the median casing and cause a differential pressure pressing the bearing flanges against side faces of the pinions.
