Abstract

A variable displacement hydrostatic power unit () is in a drive connection with an internal combustion engine (). When operated as a pump, the power unit () delivers hydraulic fluid to at least one consumer (V). When operated as a motor, the power unit () is a hydraulic starter for the internal combustion engine () and is supplied with hydraulic fluid from a hydraulic accumulator (). The displacement volume of the power unit () is set by a displacement volume control device () actuated by a positioning device (). The displacement volume control device () is displaced into a position with maximum displacement volume by a corresponding actuation of the positioning device () chronologically prior to the shutoff of the internal combustion engine (). A securing device () holds the displacement volume control device () in the maximum displacement volume position when the internal combustion engine () is shut off.
