Abstract: A regulator for an adjustable hydrostatic machine (1) having a hydraulic servo controller (4) for continuous variation of the displacement volume, with a valve device (16, 18) for controlling or regulating the servo controller (4) in dependence on the displacement volume and/or working pressure of the hydrostatic machine (1) and a second regulating valve (15) for regulating the servo controller (4) in dependence on the displacement volume, is arranged so that it can be operated without significant regulating losses in the working stream. This is done by providing a third control valve (48), controlled in dependence on the control movement of the servo controller (4), to control the pressure acting on the second regulating valve (15).

Abstract: The invention relates to a control system for automatically regulating the displacement setting of a plurality of variable-displacement hydrostatic pumps that are connected in parallel, each via a respective working pressure line, to a common consumer line and are each connected to a respective adjusting device that can be acted on by an adjusting pressure, each of said adjusting device having associated with it a pilot valve that is acted on towards a regulating position, against a counter-pressure, by a first control pressure corresponding to the pressure in the working pressure line of the respective pump and by a second control pressure corresponding to the displacement setting of the associated pump, and which in the control position regulates the setting pressure acting on the adjusting device to reduce the displacement of the associated pump. To reduce the constructional outlay and to enable the individual pumps to be regulated to the same actually required outputs despite disturbing factors, according to the invention said second control pressure (p.sub.Qi) is taken off before a throttle in the working pressure line of the respective pump and acts on the associated pilot valve via a control pressure line towards the control position.

Abstract: An axial piston machine includes a housing part, a drive shaft, which is mounted in the housing part, and a cylinder drum, which is connected to the drive shaft in a rotationally fixed manner and which accommodates a plurality of pistons. Each of the pistons bound a working chamber and are supported on a swashplate. The working chambers can be connected in alternation to a high-pressure channel and to a low-pressure channel, which extend in the housing part. An insert part is rigidly inserted into the housing part. A control surface of the insert part is directly opposite the cylinder drum. The insert part has a high-pressure channel section and a low-pressure channel section, which have approximately kidney-shaped opening areas in the control surface. The other openings of the high-pressure and low-pressure channel sections opposite the opening area in the control surface are formed radially on the insert part.

Abstract: An axial piston machine in a swash-plate construction with an actuating device. The actuating device comprises a actuating piston and a mating piston. The actuating piston and the mating piston are connected to the swash plate each with the first end thereof and can be applied with the second end thereof with a force acting in the direction of the first end. For resetting the swash plate in the direction of a resting position, an elastic element is provided on the actuating piston and on the mating piston, which is supported on a spring bearing arranged on the first side facing the swash plate of the actuating piston or of the mating piston. In the other direction, the elastic element is supported on a second spring bearing arranged on the end facing away from the swash plate of the actuating piston or of the mating piston. When the swash plate is deflected from the resting position, the second spring bearing of the actuating piston or of the mating piston is supported on a counter bearing on the housing side. The second spring bearing of the respective other actuating bearing or mating bearing is supported on a counter bearing on the piston side.
