Abstract
The invention relates to an actuating device for actuating at least one shifting element (3, 4, 5) shiftable through a shifting device (6, 7, 8), whereas the shifting device (6, 7, 8) features a pressure space (6a, 7a, 8a) with a supply (26) for a pressurized medium, along with a shut-off valve (17). It is proposed that the shut-off valve (17) is connected in an electrically controllable and torque-proof manner to at least one shifting element (3, 4, 5), and that the electrical energy for the actuation of the shut-off valve (17) is able to be supplied without contact.
