Claims (1)

Patent-Anspruch:Patent claim: Als Schutz für die Liderung der Kolben an hydraulischen Pressen die Anordnung eines mehrtheiligen Ringes e in der Ringnuth des Cylinders und oberhalb der Liderung c, welcher Ring auf seiner unteren Fläche einen Kegel k bildet, so dafs die gegen letzteren wirkende Stulpe c den Ring immer zur dichten Anlegung an den Kolben b zwingt und dadurch der Zwischenraum zwischen letzterem und dem Cylinder verdeckt wird.As protection for the liner of the pistons on hydraulic presses, the arrangement of a multi-part ring e in the ring groove of the cylinder and above the liner c, which ring forms a cone k on its lower surface, so that the cuff c acting against the latter always closes the ring tight application to the piston b forces and thereby the space between the latter and the cylinder is covered.
