Abstract
A device for controlling the connection between a pressure medium source and a medium supply container is provided in a pressure medium operated system. The device includes a control valve with a housing formed with a longitudinal bore, in which a valve member is axially displaced between two end positions by pressure of the pressure medium. The valve member includes a piston and a seat portion facing a valve seat formed in the valve housing. The piston is of the diameter larger than that of the valve seat. A bore connected to the medium supply container is provided in the valve housing which is controlled by displacement of the piston.
