20100132544 | AXIAL PISTON MACHINE HAVING A RETURN DEVICE - The invention relates to an axial piston machine comprising a pivoting cradle having variable tilt. The axial piston machine has at least one adjustment device extending substantially in the longitudinal direction of the axial piston machine. The axial piston machine further comprises a return element for returning to a position of the pivoting cradle. The return element and the adjustment device are disposed in a plane extending parallel to an axis of rotation of the axial piston machine and perpendicular to a pivoting axis of the pivoting cradle. | 06-03-2010 |
20100199838 | HYDRAULIC SYSTEM HAVING AN ADJUSTABLE HYDROSTATIC MACHINE - A hydraulic system with an adjustable hydrostatic machine is provided that includes an adjustment mechanism. The adjustment mechanism interacts with an actuating device which has at least one actuating piston delimiting an actuating pressure space. The system has a regulating valve with which, for the displacement of the actuating piston and therefore for the actuation of the adjustment device, the supply and removal of pressure medium into and from the actuating pressure chamber can be controlled, wherein the regulating valve has a valve piston which is subjected to a force of a feedback spring, which force is dependent on the position of the adjustment mechanism. The valve piston is additionally subjected to a counterforce acting counter to the force of the feedback spring, and an actuating component is provided, with which the valve piston can be subjected to a control force acting in the same direction as the counterforce or to a control force acting counter to the counterforce. | 08-12-2010 |
20100202900 | HYDROSTATIC MACHINE HAVING A CONTROL DEVICE HAVING A RETURN ELEMENT FOR CONTROLLING A REGULATING VALVE - The invention relates to a hydrostatic machine having an actuating device for adjusting a displacement volume of the hydrostatic machine, wherein the actuating device has a return element ( | 08-12-2010 |
20100206161 | AXIAL PISTON MACHINE IN A SWASH-PLATE CONSTRUCTION HAVING AN ADJUSTING DEVICE - 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. | 08-19-2010 |

20100307330 | AXIAL PISTON MACHINE - The invention relates to an axial piston machine comprising a swivel cradle ( | 12-09-2010 |
20100322789 | AXIAL PISTON ENGINE HAVING A HOUSING WITH A RADIALLY WIDENED INTERIOR PORTION - The invention relates to a hydrostatic axial piston engine ( | 12-23-2010 |
20110277624 | Adjustment Device of a Hydrostatic Machine - An adjustment device according to the disclosure of a hydrostatic machine comprises at least one adjusting piston, a control valve and a follower which is attached between the adjusting piston and control valve and couples the position of the adjusting piston back to the control valve. The follower branches off on the control valve side into two arms that openly surround a component operatively connected to the control valve and are elastically connected to a shaft of the follower. | 11-17-2011 |
20130199363 | AXIAL PISTON MACHINE - An axial piston machine includes a housing having a casting which is optimized with respect to casting. An insert ring which is optimized with respect to a pressure load is formed in the bottom of the housing. The insert ring is configured to be used with such an axial piston machine. | 08-08-2013 |
20130298754 | AXIAL PISTON MACHINE - 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. | 11-14-2013 |
