Gegenstand der vorliegenden Erfindung ist j eine Kapselradpumpe, bei der ein in einem Gehäuse umlaufendes Zellenrad mit einem in diesem Gehäuse durch Fliehkraftwiikung gebildeten Flüssigkeitsring zusammen arbeitet, in den es an verschiedenen Stellen verschieden tief eintaucht.The present invention relates to a capsule wheel pump in which one in one Housing rotating cell wheel with one formed in this housing by centrifugal force winding Liquid ring works together in that it is different in different places immersed deeply.

Gemäß vorliegender Erfindung sind das Zellenrad und das Flüssigkeitsgehäuse gleichachsig angeordnet. Zur Erreichung einer wechselnden Eintauchtiefe des Zellenrades in den Flüssigkeitsring ist im Gehäuse ein Verdränger angeordnet, der an einer oder mehreren Stellen eine Formänderung des Querschnittes des Flüssigkeitsringes verursacht, derart, daß die Tiefe des Flüssigkeitsringes an diesen Stellen vergrößert und somit die Flüssigkeit in die Zellen hineingedrückt wird.According to the present invention, the cellular wheel and the liquid housing are coaxial arranged. To achieve a changing depth of immersion of the cellular wheel in the Liquid ring, a displacer is arranged in the housing, which at one or more points caused a change in shape of the cross section of the liquid ring, such that the The depth of the liquid ring is increased at these points and thus the liquid in the Cells is pressed into it.

Auf der Zeichnung sind verschiedene Ausführungsformen des Erfindungsgegenstandes veranschaulicht.Various embodiments of the subject matter of the invention are shown in the drawing illustrated.

Bei der Zellenradpumpe gemäß Fig. 1 und 2 ist das. Zellenrad α auf einer im feststehenden Gehäuse b gelagerten Welle c befestigt. Der Deckel d des Gehäuses besitzt auf seiner Innenseite eine achsiale Kurvenfläche e, so daß zwischen ihm und der gegenüberliegenden ebenen Gehäusestirnfläche ein Raum von ungleichmäßiger achsialer Weite liegt. In den Hohlraum des glockenförmig ausgebildeten Zellenrades α greift ein als Steuerkörper dienender, nach innen gerichteter, zylindrischer Vorsprung f des Deckels d ein, dessen Zylinderfläche gegen die zylindrische Innenfläche des Zellenrades α dichtet. Im Kranze des Zellenrades ist für jede Zelle eine Öffnung g vorgesehen. Diese Öffnungen treten beim Umlauf des Zellenrades der Reihe nach abwechselnd mit einem durch den Steuerkörper f und den Deckel d führenden Saugkanal h bzw. Druckkanal * in Verbindung.In the cellular wheel pump according to FIGS. 1 and 2, the cellular wheel α is attached to a shaft c mounted in the stationary housing b. The inside of the cover d of the housing has an axial curved surface e, so that a space of uneven axial width lies between it and the opposite flat end face of the housing. In the cavity of the bell-shaped cell wheel α , an inwardly directed, cylindrical projection f of the cover d , serving as a control body, engages, the cylindrical surface of which seals against the cylindrical inner surface of the cell wheel α . In the ring of the cellular wheel, an opening g is provided for each cell. As the cellular wheel rotates, these openings alternately connect with a suction channel h or pressure channel * leading through the control body f and the cover d.

Beim Umlauf des Zellenrades α wird durch die die einzelnen Zellen trennenden Schaufeln k die im Gehäuse enthaltene Flüssigkeit mitgenommen, derart, daß sie sich unter der Wirkung der Zentrifugalkraft in einem Ring am Mantel des Gehäuses ablagert. Der umlaufende Flüssigkeitsstrom findet nun an den einzelnen Stellen des Umfangs im Gehäuse infolge Anordnung der Kurve e ein verschieden breites Bett vor. Infolgedessen erhält der Flüssigkeitsstrom dort, wo das Bett die größte Breite hat, die geringste Tiefe, dort hingegen, wo das Bett die geringste Breite hat, die größte Tiefe, d. h.' es, findet an der Stelle der kleinsten Breite eine AufstauungAs the bucket wheel α rotates, the vanes k separating the individual cells entrain the liquid contained in the housing in such a way that it is deposited in a ring on the casing of the housing under the effect of centrifugal force. The circulating liquid flow now finds a bed of different widths at the individual points of the circumference in the housing as a result of the arrangement of curve e. As a result, the liquid flow has the smallest depth where the bed has the greatest width, but the greatest depth where the bed has the smallest width, that is to say there is a damming up at the point of the smallest width

Claims

the liquid instead, so that it penetrates into the cells of the cell wheel and displaces the air contained in this, while on the opposite side where. the width is the largest, the liquid withdraws from the cells and thus sucks air into this. It is clear that in the embodiment according to FIG. R, the liquid on the stationary housing encounters considerable frictional resistance. But nothing stands in the way of the housing being designed as a rotating drum. ^ One can even owing to the concentric. Arrangement of the cellular wheel and the drum firmly connect these two parts together or produce them from one piece. Such an embodiment is shown in FIG. Of course, a relative movement of the liquid ring against the displacer is also necessary here. Therefore, according to FIG. 3, the displacer e, which is also designed as an axial curve, is not connected to the rotating drum b, but is arranged in it in a stationary manner with connection to the control body f, which is also to be held in place. In the embodiment according to FIG. 4, which otherwise corresponds to that according to FIG. 3, the displacement curve e engages outside around the cellular wheel α in corresponding cutouts m of the blades k, which are carried out to the jacket of the drum b for the purpose of better entrainment of the liquid and there extend like ribs over the entire width of the drum. In the design according to FIG. 5, the displacement body e has not been given the shape of an axial, but rather a radial curve (eccentric). Here, the control body f is also moved to the other side and a fixed housing / is arranged around the drum b, to which the control body f is connected. In the construction according to FIG. 6, the stationary eccentric displacement body used in FIG. 5 is replaced by a displacement drum e which is rotatably mounted eccentrically to the drum b by means of the axis η. This drum is carried along by the liquid ring contained in the drum b by friction and therefore offers less resistance to the movement of the liquid than a fixed displacement body. Another possible embodiment is finally given in FIG. 7. Here the displacement body e has the shape of a disk which is mounted on an inclined pin 0 and seals with its spherical circumferential surface against an inner spherical surface of the drum, whereby it is carried along by friction. Of course, there are also other design options. For example, curves can be arranged in a symmetrical arrangement on both end faces of the housing or on both sides in the rotating drum. The remaining displacement bodies shown can also be provided in a double arrangement. Furthermore, the curves or other displacement bodies can also be designed in such a way that the liquid is displaced at several points on the circumference. For this purpose you need z. B. to give only one curve according to FIG. 1 a double curvature, such that two curve valleys and two curve peaks arise. Finally, instead of the control body f engaging in the bell-shaped hollowed-out cell wheel, a flat slide control cooperating with the side surface of the cell wheel can be used, the flat slide possibly forming the side boundary of the cells in place of the related side cover plate of the cell wheel, which will be omitted. Such a flat slide could serve, for example, in the case of a stationary liquid housing according to FIG. 1, the housing end wall, which is to be provided with inlet and outlet openings. Finally, it goes without saying that, for the purpose of gradual compression or thinning, several machine units of the same type can be connected in series, which under certain circumstances can be assembled into a single machine.
