Abstract

A hydraulic system is described, in particular for a motor vehicle transmission, with an actuator, a valve, a pressure supply line and a tank line. The actuator may have a first pressure chamber and a second pressure chamber, which can have pressure applied for actuation of the actuator, wherein the pressure chambers, the pressure supply line and the tank line are each connected to a port (A, B, P, T) of the valve. The valve may have several different switching positions, in which the pressure chambers with the pressure supply line or the tank line are selectively connected to each other or shut off from each other.
