    摘要: A hydraulically actuated device for moving machine parts or the like, especially a device for pressing or fitting bearings into place in the forks of universal joints, consisting of a linear-action work cylinder, a pressure generator with a constant pressure, a supply tank with pressure medium, a main valve which controls the flow of pressure medium to provide the required amount in the work chamber of the work cylinder, a main line connecting these parts of the device, and a measurement system, which controls the main valve as a function of a measurement value, especially the center offset of the joint fork with respect to a reference axis or the like, characterized in that, between the work chamber of the work cylinder and the supply tank, a return line is provided, which has a throttle device which sharply reduces the return flow of pressure medium by comparison to the flow of medium into the work chamber.

    摘要: A clutch release bearing including cooperative inner and outer race rings with included rolling elements, and a holding ring having a first flange closely adjacent and facing a second flange of one of said rings, one of said two flanges having spiral grooves or other means for providing with a fluid hydraulic pressure between said flanges, thereby urging said inner and outer race rings together for maintaining a generally fixed axial relationship between them.
