Abstract:
A valve arrangement is configured to rectify a volumetric flow supplied by a hydraulic pump to a first pump connection or second pump connection. The valve arrangement includes a first suction valve arranged between a suction-side connection of the valve arrangement and the first pump connection. The valve arrangement also includes a second suction valve arranged between the suction-side connection and the second pump connection. The valve arrangement also includes a first pressure valve arranged between a pumping-side connection of the valve arrangement and the second pump connection. The valve arrangement also includes a second pressure valve arranged between the pump-side connection and the first pump connection. The first suction valve is acted on by the pressure of the second pump connection in the opening direction. The second suction valve is acted on by the pressure of the first pump connection in the opening direction.
