A hydraulic device comprises a housing and a shaft with a flange extending perpendicularly to a first axis of rotation. A plurality of pistons are fixed to the flange and move each in a sleeve supported by and rotatable with a barrel plate. The barrel plate is provided with a plurality of actuators for exerting counter forces (Fa) on the respective sleeves in a direction and at a location such that at least when one of the pistons is at bottom dead center under operating conditions the counter force on the cooperating sleeve acts along a line at a distance from the center point of the piston head and causes a counter torque about the center point of the piston head against the tilting torque, wherein the actuators are controlled such that the counter forces increase with increasing rotational speed of the barrel plate about the second axis of rotation.

A hydrostatic axial piston machine is disclosed, in the housing of which a drive shaft is rotatably mounted about an axis of rotation. The housing comprises a pot-like housing part having a first abutment and a cover-like housing part having a second abutment. The two abutments are clamped against one another in a sealing manner. A first fitting pin is inserted precisely into a first fitting recess of the first abutment on the one hand and into a second fitting recess of the second abutment on the other hand. A second fitting pin is provided on a side opposite the axis of rotation, which is inserted precisely into a third fitting recess of the first abutment on the one hand and into a fourth fitting recess of the second abutment on the other hand. The second fitting recess has a radial widening relative to the axis of rotation, whereby the second fitting recess is a slotted hole and/or a fitting groove.
