Die Erfindung bezieht sich auf eine rotierende Motorpumpe mit einem in einem Gehäuse laufenden Laufrad, einer im radial mittleren Bereich mündenden Ansaugöffnung und einer im radial äusseren Bereich befindlichen Ausgangsöffnung.The invention relates to a rotating motor pump with an impeller running in a housing, one in the radial direction suction opening opening in the middle area and an outlet opening located in the radially outer area.
Gemäss der Erfindung ist zur Steuerung des Pumpendtirchsatzes eine Scheibe vorgesehen, die eine veränderliche Durchflussöffnung als Neben-Durchflussöffnung zwischen der Austrittsund Ansaugleitung, also praktisch als Rückflusskanal, verschliesst bzw. freigibt. Die Verstellung der hierbei axial verschiebbaren Scheibe erfolgt zweckmässigerweise durch Verstellen eines Stifts auf einem Aussparungen aufweisenden Teil, der in einer Ebene angeordnet ist, die im Verhältnis zu einer zur Achse senkrecht stehenden Ebene geneigt ist. Die Aussparungen können Einrast-Aussparungen sein. Es ist auch möglich, die gewählteAccording to the invention, it is used to control the pump output rate a disc is provided which has a variable flow opening as a secondary flow opening between the outlet and Suction line, practically as a backflow channel, closes or releases. The adjustment of the axially displaceable Disc is expediently done by adjusting a pin on a part having recesses, which is shown in a plane is arranged which is inclined in relation to a plane perpendicular to the axis. The recesses can Be snap-in recesses. It is also possible the chosen one

Die Betätigung der Steuerungseinrichtung erfolgt durch eine; fest Djit der Welle 18 verbundene Scheibe 20. Sie gestattet die Verr schiebung der Scheibe 15 mittels eines Stiftes 27 und eines mit j Aussparungen versehenen, also gezahnten Teils 21 auf einer Ebene, die im Verhältnis zur senkrecht zur Drehachse stehenden Ebene geneigt ist. Eine Feder 22 hält den Stift 27 in den Aussparungen des Teils 21.The control device is actuated by a; Washer 20 firmly connected to shaft 18. It allows locking displacement of the disk 15 by means of a pin 27 and a toothed part 21 provided with j recesses on one plane, which is inclined in relation to the plane perpendicular to the axis of rotation. A spring 22 holds the pin 27 in the recesses of the Part 21.
Nach erfolgter Steuerung wird eine Zunge 23 in einen eigens zu diesem Zweck am Gehäuse 10 vorgesehenen Einschnitt 26 umgelegt.After the control has taken place, a tongue 23 is turned into a dedicated one for this purpose the incision 26 provided on the housing 10 is folded over.
Die Freigabe des Läufers kann dadurch erfolgen, dass die Scheibe 20 möglichst vom Gehäuse 10 weggeführt wird. Über Öffnungen 25 in der Scheibe 15, in die Vorsprünge 24 eingreifen, erfolgt der Hand-Antrieb des Laufrades 13. Danach braucht nur die Zunge 23 in den Einschnitt 26 des Gehäuses 10 zurückgebracht zu werden, um die ursprüngliche Steuerungsstellung wiederherzustellen.The rotor can be released by moving the disk 20 away from the housing 10 as far as possible. About openings 25 in the disk 15, in which the projections 24 engage, the hand drive of the impeller 13 takes place. Thereafter, only the tongue 23 is required to be returned to the recess 26 of the housing 10 to restore the original control position.
