Abstract
A hydraulic arrangement for the activation of two actuators, with a hydraulic pressure supply unit which is assigned jointly to the two actuators. The pressure supply unit is designed to be reversible in its direction of action, so that, depending on the direction of action, in each case only one of the actuators is driven.
Claims17
Hydraulic arrangement for the activation of two actuators, with a hydraulic pressure supply unit which is assigned jointly to the two actuators, wherein the hydraulic pressure supply unit is designed to be reversible in its direction of action, so that, depending on the direction of action, only one of the actuators is driven in an expanding direction, wherein each of the actuators is associated with a valve arrangement, and which is provided to connect a suction side of the hydraulic pressure supply unit to an oil sump, wherein the valve arrangements are designed as directional valves, which connect the hydraulic pressure supply unit in a first position to the respective actuator and, in a second position, to the oil sump, and wherein a hydraulic pressure, which is fed to one of the actuators, is fed back to that directional valve, which is assigned to the other actuator, to actuate that directional valve towards the second position to provide a connection between the oil sump and the hydraulic pressure supply unit through that directional valve.
