Beschreibung
Zusammenfassung:	The invention relates to a shift cylinder (70) including a cylinder element (72) having a working space (74), a first and a second piston (76, 80) received in the working space (74) displaceably relatively to it, by which the working space (74) is divided in a first working chamber (82) capable of being charged with a working medium through a first port (88) of the shift cylinder (70), a second working chamber (84) capable of being charged with a working medium through a second port (91) of the shift cylinder (70) and a third working chamber (86) disposed between the first and the second working chamber (82, 84), including at least one spring member (90) capable of being supported on the first piston (76) on the one hand and on the second piston (80) on the other hand, by means of which a force can be bilaterally applied to the pistons (76, 80), wherein a first stop (92) of the shift cylinder (70) is associated with the first piston (76), by means of which a movement of the first piston (76) towards the second piston (80) is confined, and wherein a second stop (94) of the shift cylinder (70) is associated with the second piston (80), by means of which a movement of the second piston (80) towards the first piston (76) is confined.
