Abstract
A hydraulic dual axial piston machine includes a first driving unit and a second driving unit arranged one behind the other in the direction of the axis of a drive shaft and oriented opposite each other. The first and second driving units each have a respective swashplate and single actuating piston. The first and second actuating pistons exert load on a pivot cradle in a functionally identical manner to increase or decrease a pivot angle of the respective swashplate. The first and second actuating pistons are spaced apart from a central plane of the swashplates which extends through the axis of the drive shaft such that dimensions of a housing in the direction of the pivot axes of the swashplates are minimally influenced.
