The actuating cylinder is made of metallic material and its piston rod (14) is guided in a lid (11) closing the cylinder tube (10). An electrically conductive element (29), in particular a carbon plug, is arranged in the lid (11), which element (29) is always kept in contact with the surface of the piston rod and in this way ensures that the electrical potential of the piston rod (14) is made identical to that of the other cylinder parts. This ensures that no electro-corrosion, for example, occurs. <IMAGE> |
