Abstract:
Disclosed and claimed is a double-acting cylinder comprising a cylinder housing, a first floating piston, a second floating piston and a central piston which is movable to three stationary positions along an actuation direction of the cylinder. A movement of the floating pistons in the cylinder bore is delimited by end stop arrangements. A movement of the central piston in the cylinder bore is delimited by the first and the second floating piston. Each floating piston comprises a first section and a second section. A circumferential length of the floating pistons is greater in the first section than in the second section. In the first sections a first seal is arranged for a sealing engagement with an inner wall of the cylinder bore. In the second sections a second seal is arranged for a sealing engagement with the inner wall of the cylinder bore or an inner wall of the central piston.

Claim (Index 1):
A double-acting cylinder ( 1 ) comprising a cylinder housing ( 3 ), a first floating piston ( 7 ), a second floating piston ( 9 ) and a central piston ( 11 ) which is movable to three stationary positions along an actuation direction ( 13 ) of the cylinder ( 1 ),\n wherein the cylinder housing ( 3 ) defines a cylinder bore ( 5 ) which extends along the actuation direction ( 13 ) and is delimited on opposing ends by a first and a second cylinder cap ( 15 ,  17 ), respectively, wherein a movement of the first floating piston ( 7 ) in the cylinder bore ( 5 ) along the actuation direction ( 13 ) of the cylinder ( 1 ) is delimited towards the second floating piston ( 9 ) by a first end stop arrangement ( 35 ,  73 ), wherein a movement of the second floating piston ( 9 ) in the cylinder bore ( 5 ) along the actuation direction ( 13 ) of the cylinder ( 1 ) is delimited towards the first floating piston ( 7 ) by a second end stop arrangement ( 37 ,  75 ), wherein a movement of the central piston ( 11 ) in the cylinder bore ( 5 ) along the actuation direction ( 13 ) of the cylinder ( 1 ) is delimited by the first and the second floating piston ( 7 ,  9 ), characterized in that each floating piston ( 7 ,  9 ) comprises a first section ( 47 ,  49 ) and a second section ( 51 ,  53 ), wherein a circumferential length of the first floating piston ( 7 ) in a plane extending perpendicular to the actuation direction ( 13 ) of the cylinder ( 1 ) is greater in the first section ( 47 ) than in the second section ( 51 ) and a circumferential length of the second floating piston ( 9 ) in a plane extending perpendicular to the actuation direction ( 13 ) of the cylinder ( 1 ) is greater in the first section ( 49 ) than in the second section ( 53 ), wherein in the first section ( 47 ,  49 ) of each floating piston ( 7 ,  9 ) a first seal ( 55 ) is arranged for a sealing engagement with an inner wall ( 36 ,  71 ,  77 ) of the cylinder bore ( 5 ) and wherein in the second section ( 51 ,  53 ) of each floating piston ( 7 ,  9 ) a second seal ( 57 ) is arranged for a sealing engagement with the inner wall ( 36 ,  71 ,  77 ) of the cylinder bore ( 5 ) or an inner wall ( 59 ) of the central piston.
