Abstract
A regulating device for a hydrostatic positive displacement unit, such as an axial piston machine employing the swash plate principle, includes a control valve which pressurizes a regulating piston which determines the stroke volume or the displacement volume of the positive displacement unit. An electric-hydraulic regulating device having a simple construction is provided with the control valve in the form of a slide valve which can be actuated electrically. In one configuration of the invention, the slide valve can be actuated by a stepper motor.
