Description

Regelbare Drehkolbenpumpe mit achsial verschiebbaren Kolben. Die bisher bekannten Drehkolb.enpumpen mit achsial verschiebbaren Kolben sind nur einfach wirkend, und es ist der Druck parallel der Achse nicht aufgehoben.Adjustable rotary lobe pump with axially displaceable piston. The so far known rotary piston pumps with axially displaceable pistons are only single-acting, and the pressure parallel to the axis is not released.

Die vorliegende Erhnd:ung löst die Aufgabe. eine derartige Pumpe doppelt wirkend zu gestalten, wodurch bei fast gleichen Abmessungen der einfach wirkenden Pumpe die Leistung verdoppelt, außerdem der Druck parallel der Achse fast völlig aufgehoben wird. Die Erfindung ist durch die Ab.b. t bis 6 dargestellt. Abb. i zeigt einen Längsschnitt, Abb. z einen Querschnitt nach der Linie A-B und Abb.3 einen wagerechten Längsschnitt nach der Linie C-D durch die Pumpe. Abb. q. und 5 zeigt die Pumpe in ihrer Anordnung für einen Umlaufregler. Abb. 6 zeigt einen der U-förmigen Doppelkolben der Pumpe.The present invention solves the problem. such a pump doubles to make effective, whereby with almost the same dimensions of the single-acting The pump doubles the output and the pressure is almost completely parallel to the axis will be annulled. The invention is illustrated by the fig. t to 6 shown. Fig. I shows a longitudinal section, Fig. Z shows a cross section along the line A-B and Fig.3 a horizontal longitudinal section along the line C-D through the pump. Fig.q. and Fig. 5 shows the pump in its arrangement for a circulation regulator. Fig. 6 shows one the U-shaped double piston of the pump.

Ein zylindrisches Pumpengehäuse a wird durch eine Zwischenwand b, die mit einer Bohrung für die Kolbenscheibe c versehen ist, in zwei Pumpenräume d und e unterteilt. An der Zwischenwand b sind die Büchsen b1, 1>l angegossen. Diese sind mit vier öffnungen f. ä, 1l, g1 versehen, die in den Druck-und Saugraum führen.A cylindrical pump housing a is divided into two pump chambers d and e by a partition b, which is provided with a bore for the piston disk c. The bushings b1, 1> l are cast on the partition b. These are provided with four openings f. Ä, 11, g1, which lead into the pressure and suction space.

Die auf der Welle befestigte doppelte Kolbenscheibe c ist mit radialen Schlitzen zur Aufnahme der U-förmigen Kolben k, k versehen. In der Zwischenwand b sind zwei einander radial gegenüberliegende Widerlager L und in achsial verschiebbar untergebracht. Die inneren Schenkelseiten der U-förmigen Kolben k schließen an den Seitenflächen. der Widerlager 1, nt, in entsprechenden Stellungen der ersteren, dicht ab, indem sie bei der Drehung der Kolbenscheibe c an diesen vorbeigehen. Die WiderIager ragen je nach ihrer Stellung mehr oder weniger in die Pumpenräume d und e hinein.The double piston disk c attached to the shaft is provided with radial slots for receiving the U-shaped pistons k, k. In the intermediate wall b two radially opposite abutments L and are housed axially displaceable. The inner leg sides of the U-shaped piston k close on the side surfaces. the abutment 1, nt, in corresponding positions of the former, tightly, in that they pass by the piston disc c when it rotates. The abutments protrude more or less into the pump chambers d and e, depending on their position.

Die achsiale Verschiebung der Widerlager 1, nz kann beispielsweise durch das eingezeichnete Hebelwerk bewirkt werden. Die Kolben h, k werden, um'si.e in die jeweiligen Stellungen der Widerlager 1, m zu bringen, achsial verschoben. Dies :geschieht beispielsweise durch Federringe tt, o, die an den Widerlagern befestigt sind und deren achsiale Bewegung mitmachen.The axial displacement of the abutments 1, nz can be brought about, for example, by the lever mechanism shown. The pistons h, k are axially displaced in order to bring'si.e into the respective positions of the abutments 1, m . This: happens, for example, by means of spring washers tt, o, which are attached to the abutments and which participate in their axial movement.

Die Wirkungsweise ist folgende: Wenn sich die Kolbenscheibe c unter Mitnahme der Kolben k, k im Sinne des Pfeils (Abb.2) dreht, dann treibt der in die Pumpenräume hineinragende und mit dem Widerlager 1 abschließende Kolben k (Abb. i, oben links) die Flüssigkeit nach der Öffnung f und dem Druckraum lt und saugt zugleich durch die Ö1fnung g aus dem Saugraum i Flüssigkeit an. Der Kolben k der rechtsseitigen Pumpe (unten rechts) drückt die Flüssigkeit durch die links oben (Abb. 2, hinten) liegende Öffnung f1 nach denn Druckraum, während durch ihn zugleich Flüssigkeit aus der in Abb. 2, hinten rechts, liegenden Öffnung g1 angesaugt wird. Verschiebt man das Widerlager L nach links bis an die Kolbenscheibe und damit das '\@'iderlager in nach rechts, dann wird! Druckraum und lt Saugraum; die Umlaufrichtung der Flüssigkeit ist trotz gleichgebliebener Umlaufrichtung der Kolbenscheibe geändert worden. Stehen die Widerlager L und m in der XTitte der Kolbenscheibe c, so findet keine Förderung statt, da die Kolben oben und unten gleich weit in die Pumpenräume hineinragen; die Flüssigkeit wird im Kreislauf bewegt. Die Regelungsmöglichkeit der Fördermenge geht aus dem Gesagten hervor.The mode of operation is as follows: When the piston disk c rotates in the direction of the arrow (Fig. 2) with the pistons k, k being carried along, then the piston k, which protrudes into the pump chambers and terminates with the abutment 1, drives (Fig. I, top left ) the liquid after the opening f and the pressure chamber lt and at the same time sucks in liquid through the opening g from the suction chamber i. The piston k of the right-hand pump (bottom right) pushes the liquid through the opening f1 at the top left (Fig. 2, rear) towards the pressure chamber, while through it at the same time liquid is sucked in from the opening g1 in Fig. 2, rear right will. If you move the abutment L to the left up to the piston disk and thus the '\ @' iderlager in to the right, then! Pressure chamber and lt suction chamber; the direction of circulation of the liquid has been changed despite the direction of rotation of the piston disk remained the same. If the abutments L and m are in the middle of the piston disk c, there is no delivery because the pistons protrude equally far above and below into the pump chambers; the liquid is moved in a circuit. The possibility of regulating the delivery rate emerges from what has been said.

Je mehr die Widerlager einseitig der Kolbenscheibenmitte in die Pumpenräume hineinragen, desto größer ist die Fördermenge.The more the abutment on one side of the piston disk center into the pump chambers protrude, the greater the delivery rate.

Die Pumpe kann sowohl zur Energieabgabe als zu deren Aufnahme dienen.The pump can serve both to deliver energy and to absorb it.

Wenn zwei derartige Pumpen so hintereinandergeschaltet werden, daß ihre Saug-und Druckkanäle ineinanderlaufen, dann entsteht der bekannte Umlaufregler, wie ihn Abb. 4. und 5 andeuten. Die Saug- und Druckkanäle liegen einander diagonal gegenüber. Es können, je nach Verwendung, beide Pumpen oder auch nur eine regelbar angeordnet sein.If two such pumps are connected in series so that their suction and pressure channels run into each other, then the well-known circulation regulator is created, as Fig. 4 and 5 indicate. The suction and pressure channels are diagonally opposite each other opposite to. Depending on the use, both pumps or only one can be regulated be arranged.
