Abstract
A hydraulic axial piston motor is disclosed, having a rotatable cylinder drum, in which several work pistons, each provided at one end with a slider shoe, are arranged in work cylinders so as to be axially movable, having a control plate, a swash plate, against which the slider shoes bear, a pressure plate which holds the slider shoes on the swash plate, and a pressure-applying unit, which acts on the pressure plate and comprises a hydraulic piston-cylinder arrangement. Using such a motor it is desirable for an adequate contact pressure to be produced using simple means. For that purpose, the piston-cylinder arrangement is arranged between the cylinder drum and the control plate.
