Description

Kühlvorrichtung für Brennkraftmaschinen zum Antrieb von Feuerlöschpumpen. Bei den Feuerlöschpumpen wird vielfach das Kühlwasser des Motors durch den Mantel der Kreiselpumpe geleitet, um durch diese den Motor zu kühlen. Ein derartiger Umlauf des Motorkühlwassers führt zu Unzuträglichkeiten, wenn das Feuerlöschfahrzeug eine lange Anfahrt zur Brandstelle hat. Dann wird nämlich die Kreiselpumpe, welche während der Anfahrt naturgemäß außer Betrieb ist, durch das Motorkühlwasser erhitzt, und diese Erhitzung beeinträchtigt den Wirkungsgrad der Kreiselpumpe, insbesondere, dann, wenn diese mit einer Wasserringpumpe als Entlüftungspumpe verbunden ist. Der Wirkungsgrad der Wasserringpumpen ist nämlich abhängig von der Temperatur des Wasserringes, d. h. die Saugwirkung der Wasserringpumpe nimmt mit steigender Temperatur ihres Wasserringes ab.Cooling device for internal combustion engines for driving fire extinguishing pumps. In the case of fire extinguishing pumps, the engine cooling water is often passed through the jacket the centrifugal pump to cool the engine. Such a circulation of the engine cooling water leads to inconveniences if the fire engine has a has a long drive to the scene of the fire. Then namely the centrifugal pump, which during the approach is naturally out of order, heated by the engine cooling water, and this heating affects the efficiency of the centrifugal pump, in particular, when this is connected to a water ring pump as a ventilation pump. Of the The efficiency of the water ring pumps depends on the temperature of the water ring, d. H. the suction effect of the water ring pump decreases with increasing temperature Water ring.

Dieser Mißstand wird gemäß vorliegender Erfindung dadurch beseitigt, daß die Leituirgdes Motorkühlwassers kurzgeschlossen werden kann, d. h. daß das Motorkühlwasser durch entsprechende Einstellung vom Absperrorgan entweder die Kreiselpumpe durchläuft oder aber, ohne diese zu berühren, lediglich durch den Motor und dessen Kühler kreist.According to the present invention, this deficiency is eliminated by that the line of engine cooling water can be short-circuited, d. H. that this Motor cooling water either the centrifugal pump by setting the shut-off device accordingly runs through or, without touching them, only through the motor and its Cooler circles.

Auf der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstandes schematisch in den Abb. i und :2 dargestellt. Der Motor i und die mit einer Wasserringpumpe 2 als Entlüftungspumpe verbundene Kreiselpumpe 3 sind in der üblichen Weise ausgebildet. Vom Kühlraum des Motors geht eine Leitung d. zum Kühler 5 und eine Leitung 6 zum Kühlraum der Kreiselpumpe 3, welcher seinerseits wiederum durch eine Leitung 7 mit dem Kühler 5 verbunden ist.The drawing shows two exemplary embodiments of the subject matter of the invention shown schematically in Figs. i and: 2. The engine i and the one with a water ring pump 2 centrifugal pumps 3 connected as a ventilation pump are designed in the usual manner. A line d goes from the cooling chamber of the engine. to the cooler 5 and a line 6 to Cooling chamber of the centrifugal pump 3, which in turn through a line 7 with the cooler 5 is connected.

Zwischen den beiden Leitungen 7 ist bei der Ausführungsform der Abb. i durch eine dritte Leitung 8 eine Verbindung hergestellt. In diese Verbindungsleitung 8 sowie in die beiden Leitungen 6, 7 ist je ein Absperrorgan 9, io, ii eingeschaltet.Between the two lines 7 is in the embodiment of Fig. i established a connection through a third line 8. In this connection line 8 and in each of the two lines 6, 7 a shut-off device 9, io, ii is switched on.

Die Ausführungsform der Abb.2 unterscheidet sich von derjenigen der Abb. i lediglich dadurch, daß an Stelle der Verbindungsleitung 8 und der drei Absperrorgane 9, io, i i ein einziger Dreiweghahn 12 für beide Leitungen 6, 7 vorgesehen ist.The embodiment of Fig.2 differs from that of the Fig. I only in that instead of the connecting line 8 and the three shut-off devices 9, io, i i a single three-way valve 12 is provided for both lines 6, 7.

Bei der Anfahrt des Feuerlöschfahrzeugs zur Brandstelle sind die beiden Absperrorgane io, ii geschlossen, während das Absperrorgan 9 geöffnet ist. Infolgedessen kreist das Motorkühlwasser vom Motor i durch die Leitung q. zum Kühler 5 und von diesem durch die Leitungen 7, 8, 6 wieder zum Motor i. Beim Eintreffen des Feuerlöschfahrzeugs auf der Brandstelle werden die beiden Absperrorgane io, i i geöffnet und das Absperrorgan 9 der Verbindungsleitung 8 geschlossen. Dann kreist das Motorkühlwasser vom Motor r durch die Leitung 4. zum Kühler 5 und von diesem durch die Leitung 7 zur Pumpe i, von welcher es durch die Leitung 6 wiederum zum Motor gelangt. Bei der Ausführungsform der Abb. 2 sind die leiden Kreisläufe des Motorkühlwassers lediglich durch Einstellung des beide' Leitungen 6, 7 gemeinsamen Dreiweghahns r2 ermöglicht.When the fire engine drives to the scene of the fire, the two are Shut-off elements io, ii closed while the shut-off element 9 is open. Consequently the engine cooling water circulates from engine i through line q. to cooler 5 and from this through the lines 7, 8, 6 back to the engine i. When the fire engine arrives The two shut-off devices io, i i and the shut-off device are opened at the fire site 9 of the connecting line 8 closed. Then the engine cooling water circulates from the engine r through line 4 to cooler 5 and from there through line 7 to the pump i, from which it in turn reaches the engine through line 6. In the embodiment of Fig. 2, the circuits of the engine cooling water suffer only through adjustment of the two 'lines 6, 7 common three-way valve r2 allows.

-'-Trifft das Feuerlöschfahrzeug auf der Brandstelle ein, so sind Kreiselpumpe und Wasserpumpe noch kühl, so daß die letztere ihre volle Leistung entfalten kann, ohne daß ihr Wasserring bereits durch das Motorkühlwasser in unzulässiger Weise erwärmt ist. Die Umschaltung des Kühlwasserkreislaufes braucht nicht gerade bei der Ankunft des Feuerlöschautomobils auf der Brandstelle zu erfolgen, sie kann naturgemäß auch zu jedem anderen zweckentsprechenden Zeitpunkt vor sich gehen.-'- If the fire engine arrives at the scene of the fire, so are Centrifugal pump and water pump still cool, so that the latter can perform at its best can unfold without their water ring already through the engine cooling water in impermissible Way is warmed. The switching of the cooling water circuit does not exactly need to be done when the fire engine arrives at the scene of the fire, it can naturally also take place at any other appropriate point in time.
