Description
Das Hauptpatent hat eine Einrichtung zum Gegenstande, durch welche erzielt wird, daß die Berieselung der Schußstelle stets der Schußlösung voraus gehen muß. Dies wird dadurch erreicht, daß ein Kolben unter den Druck des Berieselungswassers kommt und bewegt wird, und daß dieser Kolben auf seinem Wege den elektrischen Kontakt für die Schußlösung vermittelt. Es ist hiernach erforderlich, daß zwisehen der Ingangsetzung der Berieselung und der elektrischen Kontaktgebung eine Zeit verstreicht, die von ziemlich erheblicher Bedeutung sein muß und dies um so mehr, als der Kolben nach der Erfindung im Hauptpatent seinen Weg noch weiter fortsetzen soll, um auch die Abstellung der Berieselung zu bewirken.The main patent has a device for the subject by which it is achieved that the Sprinkling the firing point must always precede the firing solution. This is because of this achieves that a piston comes under the pressure of the sprinkling water and is moved, and that this piston provides the electrical contact for the shot solution on its way. It is then necessary that between the start of the irrigation and the electrical contacting elapses a time that is of quite considerable importance must be and all the more so as the piston according to the invention in the main patent makes its way should continue even further in order to effect the shutdown of the irrigation.
Es ist nun aber für die sofortige Wiederbereitstellung der Schußlösevorrichtung nachteilig, wenn das hinter dem Kolben im Zylinder befindliehe Wasser durch dieselbe Drosselungsöffnung, also mit demselben Zeitaufwande wieder zurücktreten muß. Dieser Nachteil soll durch die Erfindung behoben werden, und zwar geschieht dies durch Verwendung eines Wechselsitzventiles, das beim Zufluß zum Kolben einen geringeren, zweckentsprechend gewählten Zuüuß gestattet als beim Rückweg, der sich schnell vollziehen soll. Eine Auswechselung dieses Wechselsitzventiles gegen eine anderes anderer Abmessungen führt auch gleichzeitig eine andere Festlegung der Folgedauer zwischen Berieselung und Zündung herbei.It is now disadvantageous for the immediate re-availability of the release device, if the water behind the piston in the cylinder passes through the same orifice, so must step back again with the same expenditure of time. This disadvantage is addressed by the invention be remedied, this is done by using an interchangeable seat valve, which allows a smaller, appropriately chosen inflow at the inflow to the piston than on the way back, which should be carried out quickly. A replacement of this interchangeable seat valve against another other dimension also leads to another determination at the same time the duration between sprinkling and ignition.
In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown using an exemplary embodiment.
In dem Zylinder η bewegt sich gegen die Wirkung der Feder r der Kolben q wie beim Hauptpatent. Der Zufluß zum Zylinder wird aber bei der neuen Einrichtung vermittelt durch das Wechselsitzventil x, welches eine enge zentrale öffnung y hat, während es durch Flügelansätze das Wasser auch an seinem Umfange durchlassen kann. Das Wechselsitzventil χ wird nun beim Einfluß des Wassers in den Kolben hochgedrückt und legt sich schließend gegen den Zuströmungskanal z, so daß nunmehr nur noch Wasser durch den engen Kanal y einströmen kann. Beim Rückweg aber setzt das Ventil χ unten auf, und es läßt dann das rückfließende Wasser auch seitlich durch.In the cylinder η , the piston q moves against the action of the spring r as in the main patent. In the new device, however, the inflow to the cylinder is mediated by the interchangeable seat valve x, which has a narrow central opening y , while it can also let the water through at its periphery by means of wing extensions. The interchangeable seat valve χ is now pushed up when the water enters the piston and closes against the inflow channel z, so that now only water can flow in through the narrow channel y. On the way back, however, the valve χ opens at the bottom, and it then also lets the water flowing back through to the side.
