Abstract: To decrease mechanical loading on the roller thrust bearings in hydraulic pressure fluid apparatus, a hydrostatic axial slide bearing is provided, having a rotating part with an axially directed face secured to the rotating elements of the apparatus; and a stator part, formed as an axially movable element, such as a piston, within a cylinder which has pressure fluid applied thereto from a pressure fluid tap of the apparatus, the piston being formed with an opening, preferably including a choke, through which pressure fluid is applied in the region between the piston and the axially facing surface of the rotor element, to provide a counterforce against the mechanical force exerted against the thrust bearing.

Abstract: A source of hydrostatic pressure is connected to a reversible hydraulic motor over a pair of pressure lines, selectively carrying high or low pressure; a controllable pressure limiting valve is connected to the lines, and having an output connected to a drain. The controllable pressure limiting valve includes a main piston operating in a piston chamber, a settable pilot valve unit, an interconnecting line connecting fluid under line pressure to the settable pilot valve unit and a drain valve unit having a movable drain control piston connecting the interconnecting line with the side of the main piston to which the higher pressure is applied, the arrangement permitting direct drain connection of either of the pressure lines to the drain with a minimum of parts or external interconnections.
