Abstract
The present disclosure relates to an adjusting device for adjusting the swash plate of an axial piston machine comprising an adjusting piston, which is connected to the swash plate of the axial piston machine via an adjusting lever, and a regulator for adjusting the adjusting pressure acting on the adjusting piston in dependence on a control force acting on a control piston of the regulator, wherein the adjusting piston is connected to the control piston via a feedback spring. In accordance with the present disclosure the feedback spring is at least partly received in a pot-shaped recess of the control piston.

An adjusting device for adjusting a swash plate of an axial piston machine comprising:
- an adjusting piston, which is connected to the swash plate of the axial piston machine via an adjusting lever, and
- a regulator which adjusts the adjusting pressure acting on the adjusting piston in dependence on a control force acting on a control piston of the regulator, wherein the adjusting piston is connected to the control piston via a feedback spring, wherein the feedback spring is at least partly received in a pot-shaped recess of the control piston.
An adjusting device for adjusting a swash plate of an axial piston machine comprising:
- an adjusting piston connected to the swash plate of the axial piston machine via an adjusting lever,
- a regulator adjusts the adjusting pressure acting on the adjusting piston in dependence on a control force acting on a control piston of the regulator, and
- a feedback spring connecting the adjusting piston and the control piston and at least partly received in a pot-shaped recess of the control piston.
A method of adjusting a swash plate of an axial piston machine comprising:
- connecting an adjusting piston connected to the swash plate of the axial piston machine via an adjusting lever,
- adjusting pressure acting on the adjusting piston via a regulator in dependence on a control force acting on a control piston of the regulator, and
- connecting the adjusting piston and the control piston via a feedback spring wherein the feedback spring is at least partly received in a pot-shaped recess of the control piston.
