Abstract (en)

[origin: WO0112989A1] The invention relates to an axial-piston drive system with a continuously adjustable piston stroke. The inventive drive system has a drive shaft (10, 12) on which a swash plate (16) is mounted in a crank chamber (14) in such a way that it is tiltable and axially displaceable. The drive system also comprises a control device (18, 20) by which means a tilting angle and an axial position of the swash plate (16) can be adjusted, and at least one piston (26, 28) which is connected to the swash plate (16) in a driving manner and can move in a cylinder (22, 24). According to the invention, said control device (18, 20) has an adjusting unit (30, 32) which is separate from the piston (26, 28).
