    摘要: Mounting structure for housing-free hydraulic axial piston machines of the bent axis or swash plate design, having a closing plate on which a cylinder block unit with displacing pistons arranged therein is supported, and having a drive or driven shaft. The mounting structure here is designed in the manner of a basket and has a receptacle for the drive or driven shaft and at least two struts which are in each case connected at one end to the receptacle and at the other end to the closing plate in such a manner that the closing plate, the cylinder block unit and the drive or driven shaft are held—analogously as in a housing—in a functionally ready position.

    摘要: A variable-capacity swash plate type compressor including a tiltable swash plate and a rotor supported by a drive shaft and connected to the swash plate by a hinge mechanism for controlling the tilting angle of the swash plate to change the capacity of the compressor. The hinge mechanism includes a pair of support arms extending from the rotor on either side of the top dead center position of the swash plate having holes, and a pair of guide pins extending from the swash plate and having balls fitted in the holes of the support arms. The holes are circular holes having different diameters. Alternatively, the holes are a circular hole and an oblong hole having a long width in the rotating direction.

    摘要: A housing of a hydraulic pump is configured to have a servo unit detachably attached thereto so as to control tilt direction and angle of its movable swash plate. A port block is formed therein with a pair of main ports and, and a pair of main fluid passages and fluidly connecting respective main ports and to cylinders in its cylinder block. Main ports are used to have respective external pipes connected thereto so as to fluidly connect the hydraulic pump to a hydraulic motor disposed outside of the hydraulic pump, thereby constituting a hydrostatic transmission.

    摘要: A hydraulic axial piston machine includes a drive shaft, a swashplate pivotable about a pivot axis to change inclination relative to a drive shaft axis, and an actuating piston approximately parallel to the drive shaft axis. The actuating piston has a first end which engages and adjusts the swashplate and a second end which bounds an actuating chamber. Fluid flows to the actuating chamber to pivot the swashplate one direction and is forced out of the actuating chamber when the swashplate pivots the other direction. A return element on the actuating piston incorporates a position of the actuating piston and thus the inclination of the swashplate into a control valve. The return element is positioned such that its longitudinal axis and an actuating piston longitudinal axis span a plane that differs from a plane perpendicular to the pivot axis.

    摘要: A floating cup pump assembly incorporating a tilted swashplate structure with cup elements projecting away from either side of the swashplate structure. The swashplate structure is positioned between a first group of matedly engaged piston elements and a second group of matedly engaged piston elements. The piston elements rotate around a first axis and the cup elements rotate around a different axis causing the cups to reciprocate relative to the piston elements.
