Claims (1)

PatentanspruchClaim Rotationskolbenpump e, gekennzeichnet durch folgende Merkmale: Gehäuse, dessen innere Manteliläche im Querschnitt eine einbogige Trochoide dar stellt; Kolben mit Hohlrad, der mit allen der Antriebswelle parallellaufenden Kanten in jeder Bewegungsphase die innere Mantelfläche des Gehäuses berührt; der Querschnitt des Kolbens stellt ein Zweieck mit konvex gebogenen Seiten dar; Antriebswelle mit Exzenter, welcher das Hohlrad ausfüllt und die Antriebskraft auf den rotierenden Kolben überträgt am Gehäuse angebrachtes Führungsrad, auf dem das Hohlrad des Kolbens abrollt; Hohl- und Führungsrad haben ein Durchmesserverhältnis von 2 : 1; Ein- und Auslaßkanal in der dargestellten Anordnung (Bild 1 bis 4). Rotary piston pump, characterized by the following features: housing, the inner surface of which is a single-arched trochoid in cross section; Pistons with ring gear, the one with all edges running parallel to the drive shaft in every phase of movement touches the inner surface of the housing; the cross-section of the piston represents represents a triangle with convex curved sides; Drive shaft with eccentric, which fills the ring gear and transfers the driving force to the rotating piston guide wheel attached to the housing on which the ring gear of the piston rolls; Hollow- and guide wheel have a diameter ratio of 2: 1; Inlet and outlet duct in the arrangement shown (Fig. 1 to 4).
