holt wird. An einem mit dem Raum d verbundenen Druckmesser kann man die einzelnen Druckstufen ablesen und durch Einstellung der Nockensehoibe t die Druckstafen ändern.
Beim Leergang der Presse wird das Presswerkzeug vor Beendigung des Druckhubes dadurch aufgehalten, dass es sich auf den oberen Rand des Presszlinders aufsetzt. Beim Öffnen des Ventils y, :. B. durch die Daumenscheibe, wird die abgelassene Flüssigkeit durch den Kolben c angesaugt und dadurch der ursprüngliche Zustand selbsttätig hergestellt.
An Stelle der das Presswerkzeug vom Pressling zurückführenden Schwerkraft kann das Presswerkzeug unter dem Einfluss einer anderen, in der gleichen Richtung wirkenden Kraft gesetzt werden.
PATENT-ANSPRÜCHE : 1. Presse mit mechanisch angetriebenem Antriebskolben und einem lose beweglichen, unter einer Rückzugkraft stehenden Presskolben, der zwischen sich und dem Antriebskolben einen mit Flüssigkeit erfüllen Raum einschliesst, dadurch gekennzeichnet, dass während eines Arbeitshubes des Antriebskolbens (c) zur zeitweiligen Abhebung des Presskolbens (a) vom Pressling und zur mehrmaligen Druckgebung durch diesen Kolben Flüssigkeit einmal oder mehrmals ausgelassen und während des Leerlaufes des Antriebskolbens Flüssigkeit zur Füllung des Raumes (d) auf den ursprünglichen Stand ein- gelassen wird.

is picked up. The individual pressure levels can be read from a pressure gauge connected to space d and the pressure levels can be changed by adjusting the camshaft t.
When the press is idling, the press tool is stopped before the end of the pressure stroke in that it sits down on the upper edge of the press cylinder. When opening valve y,:. B. by the thumb disk, the drained liquid is sucked through the piston c and thereby the original state is automatically restored.
Instead of the force of gravity returning the pressing tool from the pressed part, the pressing tool can be set under the influence of another force acting in the same direction.
PATENT CLAIMS: 1. Press with mechanically driven drive piston and a loosely movable press piston which is subject to a retraction force, which between itself and the drive piston includes a space filled with liquid, characterized in that during a working stroke of the drive piston (c) for temporary lifting of the plunger (a) from the compact and for repeated pressure exertion through this plunger, liquid is let out one or more times and while the drive plunger is idling, liquid is admitted to fill space (d) to the original level.
