Description
Kühlwasserpumpe mit Steigleitung an Außenbordmotoren. Wird der mit einer an die Kühlwasserpumpe angeschlossenen, zum Auspuff führenden Steigleitung ausgestattete Außenbordmotor nach Abstellen von seiner Aufhängestelle losgemacht und ins Boot gelegt, so läuft die nach wassergefüllte Zuleitung ins Boot aus.Cooling water pump with riser on outboard motors. Will the with a riser connected to the cooling water pump and leading to the exhaust The equipped outboard motor is detached from its suspension point after it has been switched off and placed in the boat, the water-filled supply line runs out into the boat.
Die Ausrüstung des Steigrohres etwa mit einem Wasserhahn, der, an einer im Rohre vorgesehenen Ausflußöffnung angeordnet, während des Betriebes des Motors und der Pumpe geschlossen gehalten würde, um das geförderte Wasser ohne Verlust zum Auspuff aufsteigen zu lassen, und nach Stillstand des Motors und der Pumpe aufgedreht würde, um das in der Steigleitung stehende Wasser ins Fahrwasser rückströmen zu lassen, wäre nur eine unzulängliche Maßnahme zur Beseitigung des gekennzeichneten Übelstandes, da die richtige Wirkung einer derartig-In #-orrichtung völlig von ihrer richtigen Bedienung abhängen würde. Demgegenüber kennzeichnet sich die Vorrichtung nach vorliegender Erfindung dadurch, daß das Verschließen einer in der Steigleitung angebrachten Off-Z, beim Anlassen des Motors und der Pumpe und ebenso das Öffnen derselben beim Abstellen des Motors und der Pumpe völlig selbsttätig erfolgt.Equipping the riser with a tap, for example arranged an outflow opening provided in the tube, during the operation of the Motor and pump would be kept closed to the pumped water without loss to let rise to the exhaust, and cranked up after stopping the engine and the pump would in order to flow back the water standing in the riser into the fairway leave would only be an inadequate measure to remove the marked Disadvantage, since the correct effect of such-In # device is completely different from theirs would depend on proper operation. In contrast, the device is characterized according to the present invention in that the closing of one in the riser attached Off-Z, when starting the engine and the pump and also opening the same takes place completely automatically when the engine and the pump are switched off.
In den Abb. i bis 3 der beiliegenden Zeichnung ist der Erfindungsgegenstand in beispielsweiser Ausführungsform veranschaulicht.In Figs. I to 3 of the accompanying drawings, the subject of the invention is illustrated in an exemplary embodiment.
An die Pumpe a, die zweckmäßig auf dem Propellergehäuse steht und von der Propellerachse angetrieben wird, sind der Saugstutzen b und die Steigleitung c angeschlossen. In dieser Rohrleitung c, die an der eine Verlängerung des Kurbelgehäuses bildenden Hülse entlang läuft (Abb. i), ist nahe oberhalb der Pumpe a eine Öffnung d angebracht (Abb. 2). An diesem Steigrohr c ist ferner eine Blattfeder e so angeordnet, beispielsweise an ihrem unteren Ende mit dein Rohre vernietet, daß sie im Ruhezustande des Bootes im Wasser lose gegen die Öffnung d anliegt (Abb.3). Wird nun mit dem Anwerfen des Motors das Boot in Fahrt gebracht, so wird infolge des von dem Boote während der Fahrt auf das Fahrwasser ausgeübten Druckes die Blattfeder e vom Gegendruck des Wassers fest auf die Öffnung d gepreßt, die sie so gegeit das von der Pumpe durch die Steigleitung c gedrückte Wasser verschließt. Kommt dann das Boot und mit ihm die Pumpe beim Abstellen des Motors wieder zum Stillstand, so wird die Blattfeder e durch den Druck der in der Steigleitung c stehenden Wassersäule von der Öffnung d abgedrückt und läßt das Leitungswasser in das Fahrwasser rückströmen.To the pump a, which is conveniently located on the propeller housing and is driven by the propeller axle, the suction port b and the riser are c connected. In this pipeline c, which is attached to an extension of the crankcase forming sleeve runs along (Fig. i), there is an opening close to the pump a d (Fig. 2). A leaf spring e is also arranged on this riser pipe c in such a way that for example, riveted at their lower end to your pipes, so that they are at rest of the boat rests loosely against opening d in the water (Fig.3). Is now with the When the engine is started, the boat is in motion, as a result of the boat the pressure exerted on the fairway during the journey, the leaf spring e from the counterpressure of the water tightly pressed onto the opening d, which it thus counteracted by the pump closes off water pressed through the riser c. Then the boat comes and with me if the pump comes to a standstill when the engine is switched off, the leaf spring will be e by the pressure of the water column in the riser c from the opening d and lets the tap water flow back into the fairway.
Durch diese Vorrichtung wird somit erreicht, daß einerseits während der Fahrt und also während des Pumpenbetriebes der Verlust von Förderwasser aus der Steigleitung selbsttätig verhindert wird und andererseits bei erfolgtem Stillstand des Motors und der Pumpe das Rückströmen des in der Steigleitung stehenden Wassers ins Fahrwasser sofort selbsttätig eintritt.By this device it is achieved that on the one hand during during the journey and thus the loss of conveyed water while the pump is in operation the riser is automatically prevented and, on the other hand, when it comes to a standstill the motor and the pump prevent the water in the riser from flowing back enters the fairway automatically and immediately.
An Stelle der Blattfeder kann ein alsdann sinngemäß an der Rohrleitung c anzuordnender Lederstreifen treten; es kann eine bewegliche Abdeckvorrichtung für die Öffnung auch von wesentlich anderer Bauart Verwendung finden, insofern sie nur auf das gekennzeichnete, mit dem wechselnden Wasserüberdrucke wechselnde Spiel eingestellt ist.Instead of the leaf spring, a then analogously on the pipeline c step leather strips to be arranged; it can be a movable cover device for the opening are also of a much different type of use, insofar as they are used only on the marked game, which changes with the changing water pressure is set.
