    摘要: A gear actuator for engaging and disengaging gears in an automatic manual transmission has a single working piston or two working pistons provided with a first working piston surface and a second working piston surface. An auxiliary piston is provided also. A pressure control valve controls a pressure supplied to the second working piston surface. A shut-off valve is provided. The first working piston surface and the pressure valve are supplied with a system pressure of a hydraulic system. The first working piston surface and the pressure control valve can be decoupled from the system pressure of the hydraulic system by the shut-off valve.

    摘要: 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).
