KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. PATENTSCHRIFTPATENT LETTERING KLASSE 58«.CLASS 58 «. Zusatz zum Patente 129398 vom 11. Dezember 1900.Addendum to patent 129398 of December 11, 1900. Patentirt im Deutschen Reiche vom 28. März 1902 ab. Längste Dauer: 10. Dezember 1915.Patented in the German Empire on March 28, 1902. Longest duration: December 10, 1915. Die vorliegende Erfindung betrifft eine Verbesserung der durch Patent 129398 geschützten Steuerung für hydraulische Pressen mit Prefspumpe. Schaltet man in die Leitungen der Druckflüssigkeit zwischen dem Zuflufsregler ο und den Abflufsreglern ν bezw. vl (vergl. Patentschrift 129398) je einen Windkessel ein. so wird die darin eingeschlossene Luft wahrend des jeweiligen Prefsvorganges comprimirt. Sobald danach bei Erreichung des Höchstdruckes die Umsteuerung beginnt, indem der Sperrkolben α den Spannkolben c freigiebt, expandirt diese comprimirte Luft und wirkt treibend auf den Spannkolben c. Es wird hierdurch erreicht, dafs die Federn i in ihrer Wirkung unterstützt werden, mithin schwächer gehallen werden oder auch sammt den Theilen efh ganz in Wegfall kommen können.The present invention relates to an improvement of the patent 129398 control for hydraulic presses with prefump pumps. If you switch into the lines of the hydraulic fluid between the inflow regulator ο and the outflow regulator ν respectively. v l (see patent specification 129398) one air chamber each. so the air enclosed in it is compressed during the respective prefilling process. As soon as the reversal begins when the maximum pressure is reached, in that the locking piston α releases the tensioning piston c , this compressed air expands and has a driving effect on the tensioning piston c. It is thereby achieved that springs DAF i in their effects are supported, are therefore gehallen weaker or together with the parts efh very omission may come. Patent-A ν spruch:
Steuerung für hydraulische Pressen mit Prefspumpe nach Patent 129398, gekennzeichnet durch die Anordnung von Windkesseln in den Leitungen der Druckflüssigkeit zwischen dem Zuflufsregler (0) und den Abflufsreglern ('v bezw. V1J, wodurch die Federn (i) in ihrer Wirkung unterstützt werden und daher schwächer gehalten werden oder auch sammt den Theilen (efh) des Spannwerks ganz in Wegfall kommen können.
Patent-A ν claim:
Control for hydraulic presses with prefpump according to patent 129398, characterized by the arrangement of air tanks in the lines of the pressure fluid between the inflow regulator (0) and the outflow regulator ('v and V 1 J, whereby the springs (i) are supported in their effect and therefore can be held weaker or can be completely omitted together with the parts (efh) of the tensioning mechanism.
