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