Patent-Anspruch:Patent claim: An hydraulischen Pressen die Construction bezw. Anordnung der Steuerventile in der Weise, dafs die genügend langen Druckstangen der Auslafsventile α a\ welche sich gegen einen gemeinschaftlichen Steuerhebel stützen, in der Mittelstellung des Hebels beide Ventile offen halten und dadurch den oder die Cylinder für Vor- und Rückwärtsgang zwecks Vorfüllung mit einem Reservoir, einer Wasserleitung, einem'Windkessel oder dergleichen oder auch den Cylinder für den Rückgang mit der Atmosphäre verbinden.On hydraulic presses the construction resp. Arrangement of the control valves in such a way that the sufficiently long push rods of the outlet valves α a \, which are supported against a common control lever, hold both valves open in the middle position of the lever and thereby hold the cylinder or cylinders for forward and reverse gear for the purpose of pre-filling with a reservoir , a water pipe, a wind kettle or the like or the cylinder for the decline with the atmosphere.
