The piston-cylinder-unit (14) has a piston (110) with a piston rod (120). The piston and the piston rod have a hollow chamber, in which a rod (130) is extended, by which an electrically conducting connection is made directly or indirectly. The inner side of the piston rod is coated with an insulated layer over a part of its length. A conductive layer is placed at the outer side of the piston rod. |
