Description

Kolbenlose Pumpe Die meisten der bekannten Pumpenkonstruktionen besitzen in einem feststehenden Gehäuse ein bewegliches Förderglied, beispielsweise einen Kolben, eine Membran od. dgl. Die vorliegende Erfindung betrifft demgegenüber eine Pumpe, welche dadurch gekennzeichnet ist, daß ein Rohr an beiden Seiten verschlossen und mit je einem Ein- bzw. Auslaßventil versehen ist, wobei die Enden des Rohres gegeneinander um die Rohrachse v erdrehbar sind. Erfindungsgemäß liegt die Verdrehung innerhalb der Elastizitätsgrenze, so daß das Rohr nach Freigabe wieder von selbst in seine Ausgangsstellung zurücktritt.Pistonless Pump Most of the known pump designs own in a stationary housing a movable conveying member, for example one Piston, a diaphragm or the like. The present invention relates to a Pump, which is characterized in that a pipe is closed on both sides and is each provided with an inlet and outlet valve, the ends of the tube are rotatable against each other about the pipe axis. According to the invention, the twist is within the elastic limit, so that the pipe again after release withdraws to its original position.

Durch das Verdrehen des Rohres ändert sich das im Rohr eingeschlossene Volumen, so daß beim Verdrehen der Rohrenden ein Druckhub erzielt wird und beim Zurückgehen des Rohres in die Ausgangsstellung ein Saughub. Durch entsprechend angeordnete Saug- und Druckventile kann diese Volumenänderung zu einer Pumpwirkung verwendet werden. Erfindungsgemäß können solche Rohre als Pumpen verwendet werden, die ohnehin einer Verdrehung unterworfen sind, also beispielsweise hohle Drehstäbe im Kraftfahrzeugbau. Durch die Ausbildung derartiger Drehstäbe als Pumpen gemäß Erfindung können weitere Druckerzeuger, beispielsweise für Schmierung, Druckspeicher für irgendwelche Zwecke od. dgl. eingespart werden.By twisting the pipe, what is trapped in the pipe changes Volume, so that when turning the pipe ends a pressure stroke is achieved and when Return of the pipe to the starting position one suction stroke. By appropriately arranged Suction and pressure valves can use this volume change to produce a pumping action will. According to the invention, such pipes can be used as pumps, anyway are subject to rotation, so for example hollow torsion bars in automotive engineering. By designing such torsion bars as pumps according to the invention, further Pressure generators, for example for lubrication, pressure accumulators for any purpose or the like can be saved.
