Patentiert im Deutschen Reiche vom 24. Februar 1912 ab.Patented in the German Empire on February 24, 1912.

Die Erfindung betrifft eine Druckpumpe mit umlaufenden Kolben, die, paarweise vereinigt, in einem exzentrisch im Gehäuse gelagerten Radkörper längsverschiebbar sind. Die Kolbenpaarkörper kreuzen sich in ihrer einfachen Breite in der Maschine und besitzen seitliche Ausschnitte zum Hindurchlassen der anderen Kolbenpaarkörper. Die Erfindung besteht darin, daß je einer der Kolben jedesThe invention relates to a pressure pump with rotating pistons which, combined in pairs, are longitudinally displaceable in a wheel body mounted eccentrically in the housing. The piston pair bodies intersect in their single width in the machine and have side cutouts to let the through other piston pair body. The invention consists in that one of the pistons each

ίο Kolbenpaarkörpers eine Durchtrittsöffnung für das Fördermittel besitzt. Jeder Sektorraum vergrößert sich während der ersten Hälfte seiner Umdrehung, bis er zum' Ausgangspunkt der Drehung zurückgekehrt ist, der hier einmal ganz oben angenommen sei. Die in einem Sektorraum eingeschlossene Wassermenge würde also auf der ersten Hälfte ihrer Umdrehung ein Vakuum herstellen, wenn nicht der nachfolgende Kolben eine Durchtrittsöffnung I für das Wasser besäße. Der umlaufende Sektorraum saugt also entsprechend seiner allmählichen Vergrößerung Wasser nach und gibt die bei seiner in der zweiten Hälfte der Umdrehung stattfindenden Raumverkleinerung überschüssig werdende Wassermenge durch die Öffnung des voraufgehenden Kolbens wieder ab.ίο piston pair body has a passage opening for the conveying means. Each sector space increases in size during the first half of its rotation until it has returned to the starting point of the rotation, which is assumed here at the very top. The amount of water enclosed in a sector space would therefore create a vacuum on the first half of its revolution if the subsequent piston did not have a passage opening I for the water. The circumferential sector space thus sucks in water in accordance with its gradual enlargement and releases the excess amount of water through the opening of the preceding piston during its reduction in space during the second half of the revolution.

Auf der Zeichnung ist ein Ausführungsbeispiel der neuen Pumpe in Fig. 1 in Seitenansieht (nach Fortnahme des Gehäusedeckels) dargestellt. Fig. 2 veranschaulicht einen Querschnitt nach Linie A-B der Fig. 1. Fig. 3 ist eine Sonderabbildung des mittleren Kolbenpaarkörpers. Fig. 4 zeigt einen der beiden seitlichen Kolbenpaarkörper.In the drawing, an exemplary embodiment of the new pump is shown in side view in FIG. 1 (after removing the housing cover). FIG. 2 illustrates a cross section along line AB of FIG. 1. FIG. 3 is a special illustration of the middle piston pair body. Fig. 4 shows one of the two lateral piston pair bodies.

Das Maschinengehäuse α von außerordentlich gedrungener Form ist an den Stirnseiten des Hohlzylinders mit den Deckeln b und c abgeschlossen, die den Achsenteilen d und e als Lager dienen. Zwischen den Achsenteilen d und e wird der aus beliebig vielen Teilen bestehende Radkörper f gehalten, in dessen Führungen die mit den Öffnungen I verbundenen Kolbenpaarkörper g, h und i längsverschiebbar sind. Je nach Anzahl der KoI-benpaarkörper ist der das Kolbenpaar verbindende Mittelsteg k seitlich gegen die Stege der anderen Kolbenpaare versetzt. Die Breite der Maschine entspricht also nur einer einzigen Kolbenbreite, während ausschließlich die Stege k nebeneinander vorbeigeführt sind und um so schmaler hergestellt werden, je mehr Kolbenpaarkörper vorhanden sind. Die Höhe der seitlichen Ausschnitte jedes Kolbenpaarkörpers entspricht dem Längshub derselben, so daß die übrigen Stege k bequem hindurchfahren können. Der Hub jedes Kolbenpaarkörpers ist gleich der Exzentrizität des Achsenlagers im Maschinengehäuse. Das Fördermittel, z. B. Wasser, nimmt seinen WegThe machine housing α of extremely compact shape is closed at the end faces of the hollow cylinder with the covers b and c, which serve as bearings for the axle parts d and e. The wheel body f consisting of any number of parts is held between the axle parts d and e , in whose guides the piston pair bodies g, h and i connected to the openings I are longitudinally displaceable. Depending on the number of piston pair bodies, the central web k connecting the piston pair is laterally offset from the webs of the other piston pairs. The width of the machine thus corresponds to only a single piston width, while only the webs k are guided past one another and are made narrower the more piston pair bodies are present. The height of the lateral cutouts of each piston pair body corresponds to the longitudinal stroke of the same, so that the remaining webs k can easily pass through. The stroke of each piston pair body is equal to the eccentricity of the axle bearing in the machine housing. The funding, e.g. B. Water, takes its way

in Richtung der in Fig. ι eingezeichneten Pfeile. Entsprechend der Verschiedenheit des Durchmessers des Pumpenraumes in den verschiedenen Richtungen sind die Kolbenpaarkörper g, h und i federnd verlängerbar eingerichtet, um sich stets dicht der Wandung des Pumpenraumes anschmiegen zu können. Die Kolbenpaarkörper haben deshalb an ihrem einen Ende Gleitschuhe m, die durch Federn ίο nach außen gedrückt werden.in the direction of the arrows shown in FIG. Corresponding to the difference in the diameter of the pump chamber in the various directions, the piston pair bodies g, h and i are designed to be resiliently extendable so that they can always cling tightly to the wall of the pump chamber. The piston pair bodies therefore have sliding shoes m at one end, which are pressed outward by springs ίο.
