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: die Anordnung von mindestens drei von einander getrennten Prefsräumen FGJ in zwei nicht getrennten Prefscylindern A B in der Weise, dafs der mit einem Kolben d versehene eigentliche Prefskolben C mit einer in den Hülfsprefscylinder B ohne Abdichtung hineinragenden Kolbenstange a verbunden ist, welche einen im Hülfsprefscylinder arbeitenden Kolben b trägt, so dafs die Kolben b und d die Prefsräume FGJ von einander trennen bezw. gegen einander abdichten.1. Instead of the arrangement of at least three separate prefs spaces for hydraulic differential presses specified in claim 1 of the main patent: the arrangement of at least three separate prefs spaces FGJ in two non-separate prefs cylinders AB in such a way that the one with one Piston d provided actual Prefskolben C is connected to a protruding into the auxiliary prescription cylinder B without a seal piston rod a , which carries a piston B working in the auxiliary prescription cylinder, so that the pistons b and d separate the prefs chambers FGJ from each other. seal against each other. 2. In Verbindung mit dem im vorstehenden Ansprüche 1. angegebenen Differentialprefswerke die Anordnung des im Anspruch 2. des Haupt - Patentes bezeichneten Drehschiebers. 2. In connection with the differential pressure units specified in the preceding claims 1. the arrangement of the rotary valve designated in claim 2 of the main patent.
