Claims (2)

Patent-Ansprüche:Patent Claims: 1. An Stelle der im Anspruch 1. des Haupt-Patentes angegebenen Anordnung von mindestens drei von einander getrennten Prefsräumen für hydraulische Differentialprefswerke in einem Hauptprefscylinder die Anordnung von mindestens drei von einander getrennten Prefsräumen (HF G oder HFJ oder HFJG) in zwei getrennten Prefscylindern in der Weise, dafs der eigentliche Prefskoben (C) mit einem in einen Hülfsprefscylinder B hineinragenden Kolben bezw. mit einer Kolbenstange a versehen wird und diese Kolbenstange in dem Hülfsprefscylinder, Fig. 1, oder der eigentliche Prefskolben in dem Hauptprefscylinder, Fig. 2, oder der eigentliche Prefskolben und die Kolbenstange je in ihren Prefscylindern, Fig. 3, durch einen angefügten Kolben b d abgedichtet werden.1. Instead of the arrangement of at least three separate prefs chambers for hydraulic differential presses in a main prefs cylinder specified in claim 1 of the main patent, the arrangement of at least three prefs chambers (HF G or HFJ or HFJG) in two separate prefs cylinders in the way that the actual Prefskoben (C) with a piston protruding into an auxiliary prefix B or. is provided with a piston rod a and this piston rod in the auxiliary prefs cylinder, Fig. 1, or the actual prefs piston in the main prefs cylinder, Fig. 2, or the actual prefs piston and the piston rod each in their prefs cylinder, Fig. 3, by an attached piston bd be sealed. 2. Bei den im vorstehenden Anspruch 1. angegebenen Differentialprefswerken die Anwendung des in Anspruch 2. des Haupt-Patentes bezeichneten Drehschiebers.2. In the case of the differential pressure units specified in the preceding claim 1, the application of the designated in claim 2 of the main patent rotary valve.
