Abstract: A swash plate-type axial piston pump, in particular for hydraulic systems, has a cylinder drum (3) rotatable about an axis of rotation (7) in a pump housing (1) and in which pistons (9) are arranged axially movable. The actuating ends of the pistons are accessible from outside of the cylinder drum (3) and are supported at least indirectly on a swash plate (15). In order to set the stroke of the pistons (9) and the fluid system pressure generated, the swash plate can be swiveled to the desired angle of inclination relative to the axis of rotation (7) by an adjustment device (21), which has at least one swiveling lever (23) that can be deflected and returned in at least one direction by an actuator and that each has in at least one hydraulically actuated actuating cylinder (31, 43) one actuating piston (35) acting on one end on an articulation point (29) of the swivel lever (23).

Abstract: An axial piston pump, particularly for hydraulic systems, includes a cylinder drum (1) rotationally driven about an axis (15) in a pump housing (7). Piston cylinder units are arranged in the drum in a circle at an offset. Pistons (21) are at least indirectly supported on a swashplate (3) by their actuation end (31) accessible outside the cylinder drum (1). Between the swept volumes (19) of the piston cylinder units and a stationary fluid inlet and stationary fluid outlet of the pump housing (7), a control device (23) is arranged that has fluid channels (25, 26) for the targeted transfer of fluid from the fluid inlet into the swept volumes (19) and from the swept volumes (19) to the fluid outlet. At least one pressure compensation channel (28, 30) is provided in the control device (23), between the fluid channels (25, 26), to build or release fluid pressure in the swept volumes (19) in a targeted manner.

Abstract: An axial piston pump has a swash-plate construction, in particular for hydraulic systems. A cylinder drum (3) can be rotationally driven about a rotational axis (7) in a pump housing (1). Pistons (9) are axially displaceable and support at their actuation ends a swash plate (15). The swash plate can be pivoted by an adjusting device (21) to the desired angles of inclination relative to the rotational axis (7) for adjusting the stroke of the pistons (9) and the fluid pressure generated. The adjusting device has an adjusting piston (35) in a hydraulically actuated adjusting cylinder (31). Their movement can be transmitted to the swash plate (15) by a driven connection having a pivot joint (37, 39; 29, 43). The pivot joint is formed by a ball joint (37, 39) arranged between the piston (35) and the piston rod (41) of the adjusting cylinder (31).
