A toothed wheel machine including a housing for receiving two meshing and especially helical-toothed wheels. The toothed wheels are axially mounted in a sliding manner by axial surfaces between bearing bodies received in the housing, and radially by a bearing shaft received in the bearing bodies. During the operation of the toothed wheel machine, an axial component of a force resulting from the hydraulic and mechanical forces generated during operation acts on each toothed wheel in the same axial direction. A counter-force against the respective axial force component is applied to the toothed wheels and/or bearing shafts, each counter-force applying the same amount of pressure as the respective axial force component, or less than same.

Gear Machine for a pump or engine having bearing members with

A pump comprising a housing and two end covers receiving a drive shaft with an eccentric thereon and with a plurality of radial pistons displaceable in radial bores provided in the housing and biased by springs. An inlet passage and an outlet passage are provided in each bore receiving the radial piston. A sealing disc is inserted between the housing and one of the end covers. Sealed through openings for high pressure medium are provided in the sealing disc. The maximal feeding flow of the pressure medium is limited by throttled passages provided in the sealing disc. A pressure control valve is provided, which is connected to an inner chamber of the housing, accommodating the eccentric.
