Description

Umlaufschmiervorrichtung für ortswechselnde Explosionskraftmaschinen, insbesondere für Flugzeuge. Die Schmierung der ortswechselnden Explosionskraftmaschinen, namentlich der Flugzeugmotoren, gestaltet sich schwieriger als die der anderen Motoren, weil die Flugzeuge und damit die Motoren sich häufig schräg stellen. Während der Schrägstellung ist die Entnahme des Öles aus dem Sammelbehälter, der von dem unteren Teile des Motorgehäuses gebildet wird, eine unsichere, da das 01 nach der tiefer liegenden Seite des Sammelbehälters fließt und die Umlaufpumpe, welche an dem höher liegenden Teile des Sammelbehälters angeschlossen ist, Luft anstatt Öl ansaugt und zu den Schmierstellen drückt.Circulating lubrication device for location-changing explosion engines, in particular for aircraft. The lubrication of the location-changing explosion engines, namely the aircraft engines, is more difficult than that of the other engines because the aircraft and thus the engines are often inclined. While the skew is the removal of the oil from the collecting container, which is formed from the lower parts of the motor housing, an uncertain because the 01 flows to the lower side of the collection container and the circulation pump, which is connected to the higher-lying parts of the collecting container , Sucks in air instead of oil and pushes it to the lubrication points.

Um das Überfließen des Öles von der einen Seite nach der anderen zu verzögern, hat man den Sammelbehälter durch Scheidewände in mehrere Kammern geteilt, welche durch Öffnungen in den Scheidewänden miteinander in Verbindung stehen.To prevent the oil from overflowing from one side to the other delay, the collecting container has been divided into several chambers by partitions, which are in communication with one another through openings in the partitions.

Die vorliegende Erfindung vermeidet die Teilung des Sammelbehälters in Kammern. Eine zweizylindrige Ölabsaugepumpe entnimmt dem Sammelbehälter durch zwei möglichst weit voneinander, am besten nach dessen Enden führenden Saugleitungen das Öl und drückt es durch eine Druckleitung nach einem Hilfsbehälter. Von diesem entnimmt die Umlaufpumpe das Öl und drückt es nach den Schmierstellen des Motors. Die Einschaltung des Olhilfsbehälters zwischen Sammelbehälter und Umlaufpumpe gibt die Sicherheit, daß die Umlaufpumpe stets genügend mit Öl versorgt ist, zumal da das Frischöl auch dem Hilfsbehälter zugeführt wird. Die zweizylindrige Ölabsaugepumpe wird von derselben Welle angetrieben wie die Umlaufpumpe, wodurch ein bestimmtes Abhängigkeitsverhältnis beider Pumpen voneinander gesichert ist.The present invention avoids dividing the sump in chambers. A two-cylinder oil suction pump removes from the collecting tank two suction lines as far from each other as possible, ideally to its ends the oil and presses it through a pressure line to an auxiliary container. Of this the circulation pump takes the oil and pushes it to the lubrication points of the engine. The connection of the auxiliary oil tank between the collecting tank and the circulation pump is there the security that the circulation pump is always supplied with sufficient oil, especially since the fresh oil is also fed to the auxiliary tank. The two-cylinder oil suction pump is driven by the same shaft as the circulation pump, creating a specific The relationship between the two pumps is secured.

In der Horizontalstellung des Sammelbehälters saugen beide Zylinder der Olabsaugepumpe Öl an. In der Schrägstellung wird dagegen der eine Zylinder unter Umständen nur Luft, der andere aber stets 01 ansaugen und in den Hilfsbehälter drücken.In the horizontal position of the collecting container, both cylinders suck oil suction pump. In the inclined position, on the other hand, one of the cylinders is below Under certain circumstances only air, but the other always suck in 01 and press it into the auxiliary container.

Die beiliegende Zeichnung stellt eine Ausführungsform der Erfindung dar.The accompanying drawing shows an embodiment of the invention represent.

Die drei Pumpenzylinder a, b und c sind in einem Gehäuse vereinigt. Ihre Kolben werden von derselben Welle w angetrieben. a und b saugen mittels der beiden, nach den Enden des Sammelbehälters s führenden Saugleitungen dl und dll das 01 an und drücken es durch die Druckleitung f in den Hilfsbehälter g. Der Zylinder c saugt aus g das 01 an, drückt es durch die Druckleitungi zu den Schmierstellen des Motors. a und b bilden also die Ölabsaugepumpe, c die Umlaufpumpe. Die Steuerung der Pumpen erfolgt durch den Rundschieber 1.The three pump cylinders a, b and c are combined in one housing. Their pistons are driven by the same shaft w . a and b suck in the 01 by means of the two suction lines dl and dll leading to the ends of the collecting container s and press it through the pressure line f into the auxiliary container g. The cylinder c sucks in the 01 from g, pushes it through the pressure linei to the lubrication points of the engine. a and b thus form the oil suction pump, c the circulation pump. The pumps are controlled by the round slide valve 1.
