The cylinder (14) has a cylinder housing (18) and a pressure chamber (19) attached to a piston (20). The cylinder (16) has a cylinder housing (28) and a pressure chamber (29) attached to a piston (30). The displacement unit generates linear movement of the linkage rods together with the cylinder housing (28), such that a carriage (38) attached to the cylinder housing (28) is moved.
