    Abstract: An adjustment device for regulating torque of a hydrostatic piston machine includes a piston delimiting a chamber, a regulation valve, feedback and regulation springs, and a member. The valve has a displaceable slide to enable pressure medium to flow into or out of the chamber, a measurement surface acted on by pressure from the piston machine, and a bore open to the chamber, a side facing the chamber acted on by a chamber pressure in a first direction. The feedback spring exerts force on the slide in the first direction, depending on a position of the piston. The regulation spring exerts force on the slide in a second direction opposite the first direction. The member has a surface as large as the side of the bore such that the chamber pressure exerts force on the slide in the second direction.

    Abstract: 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.
