Description

Entlüftungsvorrichtung, insbesondere für Feuerlösch-Kreiselpumpen Auspuffstrahlsauger für Motorspritzen, um die Pumpe beim Ansaugen zu entlüften, sind bekannt.Ventilation device, in particular for centrifugal fire-fighting pumps Exhaust ejector for motor syringes to vent the pump during suction, are known.

Es ist ferner bei Motorspritzen mit Kapselschieber- oder Kolben-Entlüftungspumpe besannt, die Kupplung zum Antrieb dieser mechanischen Entlüftungspumpen durch einen federbelasteten, mit dem Druckraum der Pumpe in Verbindung stehenden Kolben automatisch auszuschalten und gleichzeitig oder vorher den in der Entlüftungsleitung befindlichen Hahn zu schließen. Bei diesen mechanischen Entlüftungspumpen hat diese automatische Ein- und Ausschaltung der Entlüftungspumpe jedoch den Nachteil, daß die Entlüftungspumpen, wenn am Saugrohr der Pumpe das Wasser längere Zeit ausbleibt, leicht heißlaufen, da die Kapselschieberpumpen ziemlich hohe Tourenzahlen machen müssen.It is also used in motorized syringes with a slide valve or piston vent pump called the clutch to drive these mechanical vent pumps through a spring-loaded piston connected to the pressure chamber of the pump automatically switch off and at the same time or beforehand the ones in the vent line Close tap. With these mechanical priming pumps, this has automatic Switching the ventilation pump on and off has the disadvantage that the ventilation pumps, if there is no water on the suction pipe of the pump for a long time, run slightly hot, since the capsule slide pumps have to make quite high numbers of revolutions.

Das Wesen der vorliegenden Erfindung besteht darin, daß diese an sich bekannte automatische Ein- und Ausschaltung mittels eines federbelasteten, mit dem Druckraum der Pumpe in Verbindung stehenden Kolbens bei Auspuffstrahlsaugern, welche bisher nur von Hand nach vorherigem Abschließen der Entlüftungsleitung ausgeschaltet werden, angewendet wird und auch mit Erfolg angewendet werden kann, weil diese Auspuffstrahlsauger auch bei längerer Benutzung, im Gegensatz zu schnellaufenden mechanischen Entlüftungspumpen, nicht heißlaufen können.The essence of the present invention is that this in itself known automatic on and off by means of a spring-loaded, with the Pressure chamber of the pump connected piston in exhaust ejectors, which previously only switched off manually after closing the vent line is used and can also be used with success because this exhaust ejector even with prolonged use, in contrast to high-speed mechanical ventilation pumps, cannot overheat.

In der Zeichnung sind beispielsweise zwei Ausführungsformen dargestellt, und mit Mist der Motor, mit P die Kreiselpumpe, mit a der Strahlsauger, mit c die Entlüftungsleitung vom Strahlsauger zur Pumpe und mit d der Entlüftungshahn bezeichnet.In the drawing, for example, two embodiments are shown, and with crap the motor, with P the centrifugal pump, with a the ejector, with c the Vent line from the jet suction device to the pump and with d the vent valve.

Bei der Ausführung nach Fig. z wird am Strahlsauger a, sobald nach erfolgtem Entlüften die PumpeP Druckwasser fördert, durch den, federbelasteten Kolben f das Doppelventil b nach links geschoben, dabei aber zuerst auf dein Weg x der Hahn d in der Entlüftungsleitung c geschlossen.In the embodiment according to Fig. Z, as soon as the pump P delivers pressurized water after venting, the double valve b is pushed to the left by the spring-loaded piston f, but first on your way x the valve d in the vent line c is closed.

Bei der Ausführung nach Fig.2 ist an Stelle des Doppelventils b ein Schiebere im Strahlsauger a so angeordnet und dieser mit dem Kolben f so verbunden, daß nach erfolgtem Ansaugen durch Vordrücken des Kolbens f auf dem Weg x zunächst der Entlüftungshahn d geschlossen und dann erst, bzw. sobald die Schieberöffnung um einen etwas größeren Betrag y nach links geschoben, der Strahlsauger abgestellt wird, wozu die Verbindung des Hahnhebels mit der Stange des Federkolbens f wie auch bei der Ausführungsform nach Fig. z entsprechend ausgestaltet sein muß.In the embodiment according to FIG. 2, instead of the double valve b, a slide is arranged in the ejector a and this is connected to the piston f in such a way that after the suction has taken place by pushing the piston f on the path x , the vent valve d is first closed and only then , or as soon as the slide opening is pushed to the left by a slightly larger amount y, the jet sucker is turned off, for which the connection of the tap lever to the rod of the spring piston f, as in the embodiment according to FIG. z, must be configured accordingly.
