摘要： A bent-axis machine comprises a housing having a control cover and a piston drum which is rotatably mounted in the housing on a valve plate and which has axial cylinders, each of which receives a piston. An adjustment system includes a pivot cradle via which the piston drum and the valve plate can be pivoted relative to the drive axis about a maximum working range which is delimited by a minimum pivot angle and a maximum pivot angle. The minimum pivot angle of the working range is shifted out of its zero position by at least 5°, and the maximum pivot angle is extended in the same way by at least 5° in order to retain the entire working range about the region left out of the lower region.

摘要： In a bent axis hydraulic machine, a back plate and cylinder barrel vary in distance from a drive plate as a stroke angle of the cylinder barrel changes, thereby minimizing unswept fluid volume in the cylinders of the barrel at any stroke angle. Distance is controlled by one or more rollers, engaging respective tracks that define a profile of contact that determines the distance as a function of the stroke angle. Telescoping fluid supply channels are employed to maintain a fluid supply to the cylinder barrel as the distance changes.

摘要： The invention relates to a hydrostatic displacer unit with a pivoting mechanism for two conveying directions for the continuous variation of the stroke of displacement pistons and with a servo system by means of which the pivoting mechanism can be moved in opposite pivoting directions. The servo system comprises at least two servocylinders, by means of which servopjstons which actuate the pivoting mechanism can be moved, and an adjusting device in each case with a pressure-reducing valve for each servocylinder. The control pistons of the pressure-reducing valves are coupled mechanically along a common axis of movement by means of a spring arrangement.
