Abstract:
A hydraulic pilot control unit includes at least one pressure control valve that can be controlled by means of an actuating device. The pressure control valve includes a control piston connected to a stem by means of a neck. The stem has a resilient operative connection to the actuating device. The neck is fastened to the stem. Thus, the mass of the control piston, which tends to oscillate, is reduced compared to the prior art.
