Abstract: The present invention relates to a gutter selection actuator as well as a method for gutter selection in a transmission. The gutter selection actuator has precisely one double-action gutter piston (2) and one valve device (20) and can be controlled by a common control pressure. A selector finger (4) of a selector shaft (3) can be engaged and disengaged with the gutter piston (2). The position and the movement of the gutter piston (2) is determined in this connection exclusively by the valve device (20).

Abstract: A hydraulic system for actuating at least two operating systems of a motor vehicle has a first hydraulic medium reservoir for storing a hydraulic medium. A distribution valve is connected to the first hydraulic medium reservoir and to the operating systems of the motor vehicle. A control unit is connected to the distribution valve which is configured to distribute the hydraulic medium from the first hydraulic medium reservoir to the operating systems of the motor vehicle and to control flow of the hydraulic medium to the operating systems of the motor vehicle such that one of the operating systems has priority with regard to supply of the hydraulic medium. A first one of the operating systems is a brake device having a brake power assist unit, a brake valve, and a master brake cylinder. The brake power assist unit is connected via the brake valve to the control unit.
