EMI2.1
Selbstverständlich ist die Erfindung nicht auf die besondere Bauart der oben beschriebenen und hier dargestellten Einrichtung beschränkt, vielmehr können die mannigfachsten Abänderungen und Ausführungsformen in Anwendung treten, ohne dass der Rahmen der Erfindung verlassen wird. Beispielsweise kann auch die Schliessbewegung noch durch eine im Raum A oder D angeordnete Feder unterstützt werden. Das Absperrventil eignet sich besonders zum Einbau in Druckleitungen, deren Arbeitsdruck stets in ein und derselben Richtung strömt. So kann auch das Absperrventil als Anfahrventil für die Lokomotivmaschine angewendet werden.
PATENT. ANSPRÜCHE :
1. Absperrventil für einfache Strömungsrichtung, welches durch eine auf einen Kolben wirkende Drucknüssigkeit gegen den Druck in der Druckleitung geöffnet wird, dadurch gekenn- zeichnet, dass der Raum auf der der Druckflüssigkeit nicht ausgesetzten Seite des Kolbens durch eine enge Bohrung oder dgl.
mit dem in der Strömungsrichtung hinter dem Absperrventil gelegenen Raum verbunden ist, so dab der durch das sich öffnende Ventil hindurchtretende Druck der Druckleitung nur stark gedrosselt sich dem Raum auf der der Druckflüssigkeit nicht ausgesetzten Seite des Kolbens mitteilt und dadurch ein vorzeitiger Stillstand des Kolbens in der Onnungsbewegung des Ventils oder eine rückläufige Bewegung desselben vermieden wird, wogegen der durch die Bohrung oder dgl. vermittelte Arbeitsdruck nach Entlüftung des Raumes auf der bis dahin der Druckflüssigkeit ausgesetzten Seite des Kolbens die Schliessbewegung des Ventils bewirkt.

EMI2.1
It goes without saying that the invention is not restricted to the particular type of construction of the device described above and shown here; rather, the most varied modifications and embodiments can be used without departing from the scope of the invention. For example, the closing movement can also be supported by a spring arranged in space A or D. The shut-off valve is particularly suitable for installation in pressure lines whose working pressure always flows in one and the same direction. The shut-off valve can also be used as a start-up valve for the locomotive engine.
PATENT. EXPECTATIONS :
1. Shut-off valve for a single flow direction, which is opened by a pressure fluid acting on a piston against the pressure in the pressure line, characterized in that the space on the side of the piston not exposed to the hydraulic fluid is opened by a narrow bore or the like.
is connected to the space located downstream of the shut-off valve in the direction of flow, so that the pressure of the pressure line passing through the opening valve is only strongly throttled and communicates to the space on the side of the piston that is not exposed to the hydraulic fluid and thus a premature stop of the piston in the Opening movement of the valve or a backward movement of the same is avoided, whereas the working pressure mediated by the bore or the like causes the closing movement of the valve after venting the space on the side of the piston that has been exposed to the hydraulic fluid.
