摘要： An adjustment device for regulating the torque of a hydrostatic piston machine with adjustable swept volume, comprises an adjustment piston delimiting an adjustment chamber, a regulation valve defining a valve bore and including a valve slide positioned in the valve bore that controls inflow and outflow of pressure medium, and first and second feedback springs configured to exert feedback force on the valve slide in first and second displacement directions dependent on a position of the adjustment piston. The device further includes a regulation spring configured to exert a force on the valve slide in a second displacement direction. During an adjustment of the adjustment piston in a direction of maximum swept volume of the piston machine, beyond a particular position of the adjustment piston, the first and second feedback springs exert an increased force on the valve slide determined only by a spring constant of the first feedback spring.

摘要： An axial piston machine has a swash plate and an adjusting device having an adjusting cylinder and a double-acting adjusting piston which is longitudinally movable in the adjusting cylinder and includes a piston and a piston rod, which is fixedly connected to the piston and is articulated to the swash plate. The joint between the adjusting piston and the swash plate is a movable swivel joint having a joint body receptacle on one part and a joint body on the other part of the adjusting piston and the swash plate. The joint body is closely guided in the joint body receptacle in the direction of movement of the adjusting piston, is rotatable about an axis of rotation running parallel to the pivot axis of the swashplate, and is movable with a directional component perpendicular to the direction of movement of the adjusting piston and perpendicular to the axis of rotation.

摘要： A hydrostatic axial piston machine has a housing. In the housing of the hydrostatic axial piston machine, an actuating pressure cylinder is formed at an angle to the drive shaft. A control valve is inserted into the actuating pressure cylinder in a cartridge type of design. In order to enable maximum movement of an actuating piston in the direction toward the control valve, the cartridge is of shortened design. To this end, an actuating pressure port, which is arranged between a high-pressure port and a low-pressure port, and an actuating pressure passage are arranged completely inside the cartridge.

摘要： A hydrostatic axial piston machine includes a swashplate with an oblique surface formed thereon. Working pistons, which revolve and are supported by the oblique surface, are axially positioned on the swashplate with respect to a drive shaft. An adjusting cylinder, coupled to the swashplate, is configured to produce a pivoting moment and pivot the swashplate about a pivoting axis. Displacement of the working cylinders per revolution around the drive shaft is adjustable by adjusting a pivoting angle of the oblique surface. The adjustment of the pivoting angle is configured to pass beyond zero degrees, such that the direction of rotation of the drive shaft is changeable. The pivoting axis is at a distance from an axis of rotation of the drive shaft, such that an internal counter pivoting moment counteracting the pivoting moment is produced during operation of the axial piston machine when the working pistons are subjected to pressure.

摘要： A regulating valve, in particular an electroproportional pivot-angle regulator for a variable-displacement pump, includes a piston bore formed in a valve housing and a regulating piston guided in the piston bore. The regulating piston is configured to be actuated in an adjusting direction via an actuator, in particular via a lifting magnet. The regulating piston is acted upon in the opposite direction by a spring force of a counterspring. The counterspring is supported via a spring plate on a supporting spring which is supported on the valve housing. The spring plate is tensioned between the supporting spring and an adjusting device by which the spring plate is configured to be displaced in relation to the valve housing in or opposite to the adjusting direction.

摘要： A hydraulic fan drive includes an adjustable variable-displacement pump by which a pressurized fluid can be sucked in and can be delivered via a pump pressure port and which has, for adjustment of the delivery volume, an adjustment device with an actuation chamber, which is delimited by an actuation surface of an adjustment piston and to which a pressurized fluid can be supplied for increasing the delivery volume and from which pressurized fluid can be displaced for reducing the delivery volume. The adjustment device further includes a counter chamber, which is delimited by a counter surface, smaller in cross section in comparison with the actuation surface, of an adjustment piston and can be acted on by pump pressure. The adjustment device also includes an actuation spring, which acts so as to adjust the delivery volume toward an extreme value.
