Abstract
In a cylinder/piston assembly including a hydraulic cylinder and a piston which is sealingly mounted and longitudinally movable within the hydraulic cylinder and which, at least on one side, bears a piston rod, wherein the hydraulic cylinder has a cylinder barrel of circular cross section which is closed at both sides by in each case one end piece, and the piston rod extends along an axis that is eccentric with respect to the cylinder barrel, a cylindrical element is provided which is anchored on the two end pieces and which extends through the piston along a second axis which is eccentric with respect to the cylinder barrel and parallel to the first axis.

A cylinder/piston assembly comprising:
- a hydraulic cylinder (2) and a piston (6) which is sealingly mounted and longitudinally movable within the hydraulic cylinder (2);
- a piston rod (7) on at least one side of the piston (6);
- the hydraulic cylinder (2) has a cylinder barrel (3) of circular cross section which is closed at both sides by in each case one end piece (4, 5);
- the piston rod (7) extends along a first axis (14) that is eccentric with respect to the cylinder barrel (3);
- a cylindrical element (11, 11′) anchored on the two end pieces (4, 5), the cylindrical element (11, 11′) extends through the piston (6) along a second axis (15) which is eccentric with respect to the cylinder barrel (3) and parallel to the first axis (14);
- and
- a position measuring device (21) arranged within the cylindrical element (11′),
- wherein the cylindrical element (11′) is tubular.
