HYDRAULIC SYSTEM AND MOTOR VEHICLE TRANSMISSION

The invention relates to a hydraulic system and a motor vehicle transmission. A hydraulic system (12), in particular for a motor vehicle transmission (10), includes an actuator (18;18'), a valve (24),a pressure supply line (26) and a tank line (28). The actuator (18;18') may have a first pressure chamber (20) and a second pressure chamber (22), which can have pressure applied for actuation of theactuator (18;18'), wherein the pressure chambers (20, 22), the pressure supply line (26) and the tank line (28) are each connected to a port (A, B, P, T) of the valve (24). The valve (24) may have several different switching positions, in which the pressure chambers (20, 22) with the pressure supply line (26) or the tank line (28) are selectively connected to each other or shut off from each other. At least in the starting position of the valve (24), there is a fluid connection between the pressure chambers (20, 22). 本发明涉及液压系统以及机动车变速器。液压系统(12)、尤其是用于机动车变速器(10)的液压系统具有促动器(18；18')、阀(24)、压力供应线路(26)和箱线路(28)。促动器(18；18')具有能被加
