Abstract

The invention relates to an axial piston pump with at least one pump element, which includes a piston disposed in a housing, with a drive shaft upon which a swash plate for driving the piston is disposed. The swash plate is non-rotatably fixed, but can pivot around a swash plate pivot axis which extends perpendicular to the longitudinal drive shaft axis (A), and with a device for adjusting a pivot angle between the drive shaft and the swash plate. In order to be able to adjust the oblique position of the swash plate in a simple manner, even during pump operation, it is provided that the device for adjusting the pivot angle of the swash plate has a displacing device disposed in a stationary manner on the housing. The displacing device acts on the swash plate via an intermediate member, which rotates jointly with it, on one end of the swash plate pivot axis to adjust pivot angle of the swash plate in the axial direction of the drive shaft so that the swash plate is secured in the adjusted pivot position when the drive shaft rotates.
