Abstract
An adjustable axial piston machine having a bent axis design having a cylindrical drum rotatably supported on a swivel carriage which has a pair of channels formed therein. One channel is connected with a fluid feed channel and the other channel is connected with a fluid discharge channel. The cylindrical drum is connected to a rotatable shaft and has a plurality of pistons located in cylinders formed in it. A housing for the swivel carriage has a concave guide surface for the face of the swivel carriage facing the guide surface. Support pistons are pivotably connected at one end to the machine housing and supported on the swivel carriage. A plurality of pairs of counteracting servo pistons adjust the position of the support pistons and the cylindrical drum to modify the length of the stroke of the pistons located within the drum.
