摘要

The device (1) has a shifting element (3) assigned to a shift rod (2), actuatable by pressurizing medium, and arranged movably along the rod. A pressure chamber (4) is formed for the actuation of the element, where the chamber is arranged along the rod and is subjectable with the medium. The rod is guided through the chamber in a pressure-tight manner. An active surface is provided in the chamber, where the surface stays in effective connection with the rod and is subjectable with the medium in a sealed manner. A piston (5) is arranged in the chamber.
