KLASSE B9: Pumpen.CLASS B9: Pumps.

Es ist ein sehr grofser Mangel der Rotationspumpen, bei denen zwei Halbcylinder sich dicht in einem Gehäuse drehen, dafs der dichte Gang dieser Halbcylinder bereits nach kurzem Gebrauch nicht mehr vorhanden ist und infolge dessen die Pumpe nicht mehr wirkt.There is a very great defect in rotary pumps, in which two half-cylinders meet Rotate tightly in a housing, so that the tight rotation of these half-cylinders after a short time Is no longer in use and as a result the pump no longer works.

Diesem Mangel ist durch vorliegende Neuerung abgeholfen. Auf beiliegender Zeichnung ist eine damit versehene Pumpe dargestellt, und zeigt Fig. ι den Querschnitt einer neuen Pumpe, Fig. 2 einen Theil des Querschnittes einer bereits ,ausgelaufenen Pumpe, Fig. 3 den Längsschnitt derselben.This deficiency has been remedied by the present innovation. On the accompanying drawing a pump provided with it is shown, and Fig. ι shows the cross section of a new pump, FIG. 2 shows part of the cross section of a pump that has already run out, FIG. 3 shows the longitudinal section the same.

In das Gehäuse α sind die Metallschalen bx b.2 eingelegt, in welchen sich die rotirenden halbcylinderförmigen Kolben C1 C2 dicht drehen. Diese Schalen sind mit Nasen oder Rippen dx d.2 versehen, mit welchen sie in entsprechende Oeffnungen eA e.2 des Gehäuses eingreifen, und auf welche die Stellschrauben /,/2 drücken, vermittelst deren diese Schalen nach Abnutzung stets wieder dicht an die Kolben gedrängt werden können. .The metal shells b x b are in the housing α. 2 inserted, in which the rotating semi-cylindrical pistons C 1 C 2 rotate tightly. These shells have lugs or ribs d x d. 2 provided, with which they are in corresponding openings e A e. 2 of the housing engage, and on which the adjusting screws /, / 2 press, by means of which these shells can always be pushed tightly against the pistons again after wear. .

Die in die Gehäuse eingesetzten Keile Ar1 k2 drängen die Schalen vorn zusammen, so dafs auch an diesen Stellen der dichte Schlufs wieder hergestellt wird (Fig. 2). The wedges Ar 1 k 2 inserted into the housing force the shells together at the front, so that the tight seal is also restored at these points (FIG. 2).
