    摘要: An axial piston pump arrangement in which pistons are guided in cylinders provided in a cylinder block. The latter has channels for releasing liquid pressure within the cylinders in an area between kidney-shaped control openings that are arranged in the distributor plate. The channels are arranged in the cylinder block and feed into the cylinders at a location on the cylinder walls, which is uncovered by the pistons when the swash plate actuating the pistons, is at a substantially large inclination. These channels lead from the outside of the cylinder block to the internal walls of the cylinders, and are arranged radially in the cylinder block in the form of bores. At least two of the channels are arranged at various distances from the distributor plate in the area of the cylinder walls, so that an increasing number of channels is uncovered with increased inclination of the swash plate. The channels may have increasing diameter at increasing distance from the distributor plate.
