The device (18) has an actuator comprising an adjusting ring (32) held and mounted on inner sleeves in a non-relocatable and rotatable manner. The actuator is driven by an electric motor. A groove-like adjusting crank is introduced at an outer periphery in the adjusting ring, where the adjusting crank is inclined to a circumferential direction. A spring plate is guided by a cylindrical guide section (34) and the inner sleeves on the adjusting ring in an axially movable manner. The spring plate is engaged into the adjusting crank of the adjusting ring. |
