Description

Schieber mit Kugel als Umsteuerorgan für mittels Auspuffgase arbeitende Entlüftungsvorrichtungen von Kreiselpumpen Durch das Hauptpatent ist unter Schutz gestellt eine Einrichtung zum Entlüften von Kreiselpumpen durch einen mittels der Auspuffgase einer Verbrennungsmaschine betriebenen, an die Saugseite der Pumpe angeschlossenen Ejektor, wobei der Ejektor in eine Abzweigung der Auspuffleitung eingeschaltet ist und die Abzweigstelle und die Auspuffleitung abwechselnd mittels eines Umstenerungsorganes geöffnet oder geschlossen werden können, dadurch gekennzeichnet, daß als Umsteuerungsorgan eine Kugel verwendet wird, die durch eine von außen zu betätigende Vorrichtung hin und her geschoben werden kann.Slide with ball as a reversing device for those working with exhaust gases Venting devices of centrifugal pumps The main patent is under protection provided a device for venting centrifugal pumps by means of the Exhaust gases from an internal combustion engine, connected to the suction side of the pump Ejector, whereby the ejector is switched on in a branch of the exhaust line and the branch point and the exhaust line alternately by means of a changeover device can be opened or closed, characterized in that as a reversing member a ball is used, which is driven by an externally operated device and can be pushed here.

Es hat sich nun gezeigt, daß auch die Wahl eines sehr widerstandsfähigen Werkstoffes für die Kugel nicht hindert, daß die Kugeloberfläche durch den Angriff der Auspuffgase früher oder später rauh wird, wodurch dann die Abdichtung leidet. Materialien, die genügend widerstandsfähig wären, die sich aber nicht so bearbeiten lassen, daß hierdurch die genaue Kugelform sichergestellt werden könnte, sind selbstverständlich von vornherein hier-,unverwendbar.It has now been shown that even choosing a very resistant Material for the ball does not prevent the ball surface from being attacked the exhaust gases will sooner or later become rough, which will damage the seal. Materials that would be sufficiently resistant, but that do not work in such a way let that the exact spherical shape can be ensured in this way, are of course here from the start, unusable.

Gemäß der vorliegenden Erfindung wird eine andauernd von Störungen freie Wirkungsweise der als Umsteuerungsorgan benutzten Kugel dadurch gewährleistet, daß die Kugel in einem verschiebbaren glockenförmigen Betätigungsorgan eingeschlossen ist, durch welches:.ysie.'dem schädigenden Einfluß der Auspuffgase entzogen ist, ohne aber hierdurch in ihrer Wirkungsweise behindert zu sein. In diesem Valle braucht das Material der Kugel nicht so widerstandsfähig zu sein, wie wenn ein unmittelbarer Angriff der Auspuffgase möglich wäre.According to the present invention, one becomes persistent of disturbances the free operation of the ball used as a reversing device is guaranteed, that the ball is enclosed in a sliding bell-shaped actuator is by which: .ysie. is removed from the damaging influence of the exhaust gases, but without being hindered in their mode of operation. In this Valle needs the material of the sphere not to be as resistant as if an immediate one Attack of the exhaust gases would be possible.

Die Zeichnung zeigt eine Ausführungsform eines solchen Umsteuerungsorgans im Schnitt. In der Zeichnung ist ebenso wie in der des Hauptpatentes mit i die an der Auspuffseite der Maschine angeschlossene Verteilungskammer, mit 3 die Auspuffleitung, mit 5 das Ejektorgehäuse, mit 6 das von der Saugseite der Pumpe herkommende Entlüftungsrohr, mit 12 die Spritzdüse und mit 13 die Fangdüse des Ejektors bezeichnet. Die Kugel 8, die bald das Auspuffrohr 3, bald den Ejektor 12, 13 sperren soll, wird von außen her durch ein sie umschließendes Organ mittels der Stange ii hin und her bewegt, und dieses die Kugel 8 umfassende Organ -ist nicht mehr, wie bei der Konstruktion nach dem Hauptpatent, ringförmig gestaltet, sondern, wie 16 zeigt, glocken-oder haubenförmig, und zwar derart, daß die Kugel gegen oben zu gänzlich abgedeckt ist, so daß sie mit den Auspuffgasen überhaupt nicht in unmittelbare Berührung kommen kann. Jetzt kann die Kugel aus einem minder widerstandsfähigen Material bestehen und wird dennoch ständig eine gute Abdichtung des einen oder anderen Sitzes gewährleisten.The drawing shows an embodiment of such a reversing element on average. In the drawing, as in that of the main patent, with i is the distribution chamber connected to the exhaust side of the machine, with 3 the exhaust pipe, with 5 the ejector housing, with 6 the ventilation pipe coming from the suction side of the pump, with 12 the spray nozzle and 13 denotes the catch nozzle of the ejector. The ball 8, which is soon to block the exhaust pipe 3, soon the ejector 12, 13, is from the outside moved back and forth through an organ surrounding it by means of the rod ii, and this organ encompassing the ball 8 is no longer as it was in the construction according to the main patent, ring-shaped, but, as 16 shows, bell-or hood-shaped, in such a way that the ball is completely covered at the top, so that they do not come into direct contact with the exhaust gases at all can. Now the ball can be made of a less resistant material and will still ensure a good seal of one or the other seat.

In baulicher Beziehung kann die beschriebene Vorrichtung in mannigfacher Weise ausgebildet sein.In structural terms, the device described can be used in many ways Way to be trained.
