Abstract

A hollow cylinder accommodates a piston with a foot at the free end, and has a supporting head with a claw, the distance between which can be altered as desired. Inside the cylinder (3) is a further fixed one (4) coaxial to it. The piston (7) is in the form of a further hollow cylinder with seals, guided between the other two. The end of the piston furthest from the foot (8) can be guided in relation to the outer cylinder (3) by means of an intermediate piece (19) with an opening (22) passing right through it.
