  • Hydraulic regulating device
    Patent number: 10352318
    Abstract: A hydraulic regulating device includes a continuously adjustable regulating valve with a control piston. The control piston is displaceable in a first direction in which a connection of a pump port to an actuating-pressure port is configured to be controlled to open. The control piston is also displaceable in a second direction in which a connection of the actuating-pressure port to a tank port is configured to be controlled to open. In the first direction, the pump pressure acts on the control piston, and in the second direction, a control pressure and a spring act on the control piston. During movement of the control piston in the first direction, a damping connection, equipped with a damping nozzle, from the pump port to the tank port is configured to be controlled to open.
