Patent-Ansprüche: Patent claims: i. Druckmittelantrieb für Kontaktwalzen und andere Schaltapparate mit einer Mehrzahl von Steuerstellungen, Lei dem die Stellung eines Antriebskolbens auf einem bestimmten Teile seines Hubes durch 'die Wirkung eines Differentialkolbens bestimmt wird, dadurch gekennzeichnet, daß die Durchmesser so vieler Kolbendruckflächen verschieden sind als Steuerstellungen möglich sind.i. Pressure medium drive for contact rollers and other switching devices with a Multiple control positions, depending on the position of a drive piston a certain part of its stroke by 'the action of a differential piston is determined, characterized in that the diameter of as many piston pressure surfaces are different than Control positions are possible. 2. Druckmittelantrieb nach Anspruch 1, dadurch gekennzeichnet, daß Kolben, ue vom gleichen Ventil unter Druck gesetzt werden, konzentrisch ineinander angeordnet sind.2. Pressure medium drive according to claim 1, characterized in that piston, ue are pressurized by the same valve, arranged concentrically one inside the other are.
