A follower device in the reservoir contacts the interior wall of the reservoir in a sliding and sealing manner, and the follower device is movable up and down in the reservoir from a first position to a second position in response to a changing lubricant level. A valve is in fluid communication with the inlet and is configured to selectively prevent a flow of the lubricant through the inlet. A connector operatively connects the follower device to the valve unit such that the flow of the lubricant through the inlet is prevented when the follower device is in the second position. The connector is configured such that the valve is positionable independently of the reservoir.

Abstract: In a drive unit which has an axial piston pump and an electronic control unit, the axial piston pump is pivoted with a method in which pressure-reducing valves which act in opposition to one another are suddenly energized. Since in this respect no orifices are provided in the adjustment device, a so-called initiation jump of the excited current gives rise to a sudden reduction in the assigned actuating pressure or the actuating pressure difference formed therefrom. Then, a zero crossover jump of the excited current or of the excited currents is carried out in order to overcome the centering spring and therefore ensure a continuous zero crossover of the axial piston pump. Furthermore, a hydrostatic traction drive includes such a drive unit.
