PATENTAMT.PATENT OFFICE.
Bekanntlich erzielt man Kolbenpufferwirkung für Dampfhämmer und Druckübersetzer bei Pressen, Scheren o. dgl. durch Federgegendruck oder auch durch Drosselung eines vom Kolben eingeengten Gemisches. Diese Einrichtungen erfordern zur Vernichtung der lebendigen Kraft der Kolbenmasse einen langen Pufferweg.It is well known that a piston buffer effect is achieved for steam hammers and pressure intensifiers in presses, scissors or the like. By spring counter pressure or by throttling a the mixture concentrated by the flask. These facilities require the destruction of the living force of the piston mass a long buffer path.
In vorliegender Erfindung ist eine Einrichtung geschaffen, mit welcher durch Kompression des ganzen vom Kolben abgeschlossenen Gemisches der Pufferweg so kurz wie möglich wird und die Pufferwirkung während des Betriebes reguliert werden kann.In the present invention there is provided a device with which by compression of the entire mixture closed by the flask, the buffer path is as short as possible and the buffer effect during of operation can be regulated.
Die neue Einrichtung ist auf beiliegender Zeichnung an einem Druckübersetzer dargestellt. The new device is shown on the enclosed drawing on a pressure intensifier.
Im Treibzylinder α bzw. im Treibkolben c ist ein Einlaßventil g angebracht, derart, daß es durch den Kanal/" bzw. fl mit dem Ein- und Auslaßkanal k in Verbindung steht. In der Bodenöffnung m des Rückschlagventils g oder auch gesondert am Zylinder oder am Treibkolben ist ein Auslaßventil i angebracht.In the drive cylinder α or in the drive piston c , an inlet valve g is attached in such a way that it communicates with the inlet and outlet channel k through the channel / ″ or f l . In the bottom opening m of the check valve g or separately on the cylinder or an outlet valve i is attached to the drive piston.
Dasselbe kann vermittels der Schraube / durch die Feder e von außen so eingestellt werden, daß es durch einen bestimmten Überdruck im Zylinder sich nach dem Verbindungskanal f bzw. f1 hin öffnet.The same can be adjusted from the outside by means of the screw / spring e so that it opens to the connecting channel f or f 1 through a certain overpressure in the cylinder.
Die Wirkungsweise vorliegender Erfindung ist folgende:The present invention works as follows:
Sobald Dampf o. dgl. für den Preßhub in den Kanal k eingelassen wird, strömt derselbe durch den Kanal/" bzw. y1, öffnet das Einlaßventil g und treibt den Kolben vor. Bei seinem Vorgehen öffnet der Treibkolben allmählich den Kanal k unmittelbar zum Zylinder hin, worauf nunmehr das Druckmittel durch diesen einströmt und das Einlaßventil g durch die Feder h o. dgl. geschlossen wird, so daß der Dampf für die Weiterbewegung des Kolbens nur noch durch den Kanal k in den Zylinder einströmt.As soon as steam or the like is admitted into channel k for the pressing stroke, it flows through channel / ″ or y 1 , opens inlet valve g and drives the piston forward. As it moves, the drive piston gradually opens channel k directly to Cylinder, whereupon the pressure medium flows in through it and the inlet valve g is closed by the spring h or the like, so that the steam for the further movement of the piston only flows into the cylinder through the channel k.
Bei dem Dampfauslaß und dem gleichzeitig erfolgenden Rückgang des Kolbens c schließt derselbe vor Hubende den Kanal k ab. Infolgedessen wird zuerst der zwischen Kolben und Zylinderdeckel befindliche Dampf komprimiert, und wenn der Überdruck so groß geworden ist, daß er das Ventil i öffnet, entweicht das Komprimat durch den Kanal f bzw. f1 in den Kanal k. At the steam outlet and the simultaneous retraction of the piston c , the same closes off the channel k before the end of the stroke. As a result, the vapor located between the piston and cylinder cover is first compressed, and when the overpressure has become so great that it opens valve i , the compressed material escapes through channel f or f 1 into channel k.
