Date Jun. 20, 1996Pressure medium actuated control cylinder for wear compensation. A cylinder chamber includes two displaceable pistons. One piston has a first piston rod which extends outside the cylinder, and a second piston rod which extends into a through-bore in the second piston. The second piston rod has a bore, into which a rod-shaped resistor extends and penetrates an annular current collector fixed in the bore. The resistor and the current collector form a position sensor in the form of a linear potentiometer which indicates the position of the piston in the cylinder.</p> |
