Hydraulic cylinder with internal displacement conversion

The simple inexpensive and proven method of converting the displacement via a linear potentiometer which is attached to the cylinder head and is felt by a slider attached to the piston has hitherto been obstructed by the fact that there must be protection against twisting on the piston or on the piston rod to ensure a permanent slider contact. According to the invention, this problem is eliminated by a bearing disc which is arranged axially undisplaceably but rotatably in the piston by means of which the linear potentiometer is carried through centrally axially displaceably but untwistably, the slider being mounted on the bearing disc. The cylinder can thus be installed in any desired way without having to take into consideration protection arrangements against twisting.
