Axial piston pump

A hydraulic axial piston pump, comprising:

• a pump housing including a connecting plate with a stationary fluid inlet and a stationary fluid outlet;
• an axis in said pump housing;
• a drivable cylinder drum rotatable about said axis within said pump housing;
• a swash plate in said pump housing;
• a plurality of piston-cylinder units disposed in a circle at an offset in said cylinder drum, said piston-cylinder units including swept volumes and pistons supported at least indirectly on said swash plate by actuating ends of said pistons, said actuating ends being accessible from outside said cylinder drum;
• a control device between said swept volumes and said fluid inlet and said fluid outlet, said control device having fluid channels for transferring fluid from said fluid inlet into said swept volumes and from said swept volumes to said fluid outlet;
• a first pressure compensation channel being in said control device between said fluid channels and being selectively connectable to said swept volumes for establishing or relieving fluid pressure in said swept volumes, said first compensation channel being on said control device such that only one of said swept volumes is connectable to a first high pressure compression chamber at a time, said first high pressure compression chamber extending in a lower housing part of said pump housing with a longitudinal axis of said first high pressure compression chamber being disposed radially outward relative to said axis in said pump housing;
• and a second pressure compensation channel selectively connecting only one of said swept volumes to a pressure sink at a time, said pressure sink being a tank connectable to a respective one of said fluid channels only via one of said swept volumes, said second pressure compensation channel being arranged on said control device such that said second pressure compensation channel is closable to one of said swept volumes only after a connection to that swept volume from said fluid inlet is established whereby that swept volume is connected to said second pressure compensation channel and said fluid inlet at a same time.
