Description

Sicherheitsvorrichtung an aus Pumpe und Motor bestehenden Flüssigkeitsgetrieben Durch das Patent 475 47o ist eine Sicherheitsvorrichtung an aus Pumpe und Motor bestehenden Flüssigkeitsgetrieben geschützt, die darin besteht, daß für wechselweise als Saug- und Druckleitung arbeitende Übertragungsleitungen jeder Leitung ein Rückschlagventil zugeordnet ist, das durch Absperrvorrichtungen gesteuert wird. Unter anderem ist dabei auch eine besondere Ausführungsform geschützt, bei der als Absperrvorrichtung der Umlaufschieber dient. Eine besonders einfache Ausführungsform dieser Anordnung erhält man nach der Erfindung; wenn man das Rückschlagventil nicht, wie im Patent 475 470 gezeigt, am Schiebergehäuse, sondern am Schieber selbst befestigt, also die Saugseite und die Druckseite des Umlaufschiebers durch einen mittels Rückschlagventils gesteuerten Kanal verbunden wird.Safety device on fluid drives consisting of pump and motor The patent 475 47o provides a safety device on the pump and motor existing liquid gear protected, which consists in that for alternately Transfer lines working as suction and pressure lines, each line has a check valve is assigned, which is controlled by shut-off devices. Among other things is a special embodiment is also protected, when used as a shut-off device the rotary valve is used. A particularly simple embodiment of this arrangement obtained according to the invention; if you don't have the check valve, as in the patent 475 470 shown on the valve body, but attached to the valve itself, so the suction side and the pressure side of the rotary valve through a non-return valve controlled channel is connected.

Eine Ausführungsform des Gegenstandes der Erfindung ist in der Zeichnung veranschaulicht. Mit 14 ist die Druckleitung bezeichnet, mit 15 die Saugleitung, rnit 30 das Schiebergehäuse, nlit 35 der Schieber selbst. Zwischen der Druckseite 36 und der Saugseite 37 ist am Schieber 35 das Ventil 34 an-. geordnet, das :einen Verbindungskanal zwischen diesen leiden Seiten verschließt. Je nach der Lage des Schiebers wird die überbrückung der Arbeitsleitungen im richtigen Sinne ermöglicht.An embodiment of the subject matter of the invention is illustrated in the drawing. 14 designates the pressure line, 15 the suction line, 30 the valve body, 35 the valve itself. arranged that: closes a connection channel between these suffering sides. Depending on the position of the slide, the bridging of the working lines is made possible in the right sense.

Die Anwendung des Ventils :im Schieber ist nicht, wie im Beispi*el gezeigt, auf Muschelschieber beschränkt, sie ist für jede beliebige Schieberfdrm brauchbar. Man könnte -beispielsweise auch wie im Patent 475 47o Kolbenschieber verwenden und die Ventile in den Kolbenplatten' anordnen.The use of the valve: in the slide is not, as in the example shown, restricted to mussel slide, it is for any slide type useful. One could - for example, also as in patent 475 47o piston valves use and place the valves in the piston plates'.
