Abstract: An eccentric pump with lock valve and with bidirectional rotational operation, mainly for lubricant circulation of drives comprises a stationary outer casing having two parallel side walls and a cylindrical inner surface between the side walls, and further having inlet and outlet openings being sealingly separated and terminating in the cylindrical inner surface, a middle shaft arranged within the casing concentrically to the cylindrical inner surface and having a cylindrical surface being eccentric to the middle shaft as well as to the cylindrical inner surface of the casing, a circular sealing ring being sealingly displaceable in respect of the eccentric surface of the shaft as well as to inner wall portions of the casing, and further having a radial slot sealingly engaging a stationary pin with its both limiting surfaces.

Abstract: A driven axle assembly for vehicles has a lubricant circulation system, and the axle assembly comprises an axle housing with a main drive and a lubricant liquid in its inside, hollow axle casings fixed to both sides of the axle housing, a hollow wheel hub rotatably connected to each axle housing, the wheel hub having a flange for carrying a vehicle wheel rim as well as, in its inside, a planetary gearing and a multi-plate friction type wet brake, the main drive and the planetary gearing as well as the multi-plate wet brake being interconnected with a drive shaft on both sides of the main drive, respectively, and mechanism for making a lubricant flow within the axle assembly.
