ABSTRACT:
An automatic selector device for a multi-gear change-speed gearbox permits selection of the gears by a respective gear apparatus, e.g., clutch or brake, which is actuated by a selector actuator. The operating pressure of the selector actuator is switched on and off in each case by a selector valve. The selector valves are connected to a multi-path control valve for actuation by way of a control pressure force, and the control valve is actuated by an electromotive valve actuator whose operation depends on an electronic control unit.
