Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung betrifft eine nachstellbare Dichtung für Rotationspumpen mit innen verzahntem Rotationscylinder und mit diesem kämmendem verzahnten Förderkolben, vermöge deren zweckmäfsiger Anordnung und Ausbildung es möglich wird, Kolben und Cylinder bei eingetretenem Verschleifs von aufsen her derart abzudichten, dafs sowohl der Pumpe die volle Leistung erhalten bleibt, als auch deren Antrieb keinerlei Steigerung des Kraftaufwandes bedarf.The present invention relates to an adjustable seal for rotary pumps with internally toothed rotary cylinder and with this meshing toothed delivery piston, by virtue of their expedient arrangement and design, it is possible to use pistons and cylinders in the event of wear and tear, to be sealed from the outside in such a way that both the pump the full power is retained, as well as its drive no increase in effort requirement.

Fig. ι der Zeichnung veranschaulicht die Pumpe in Stirnansicht, Fig. 2 im Längsschnitt, Fig. 3 im Querschnitt, Fig. 4 im Grundrifsschnitt. Fig. Ι the drawing illustrates the pump in front view, Fig. 2 in longitudinal section, Fig. 3 in cross section, Fig. 4 in plan section.

x Im Pumpengehäuse b dreht sich concentrisch der innen verzahnte Rotationscylinder /, mit welchem ein auf excentrisch zu diesem angeordneter Treibwelle m befestigter verzahnter Förderkolben / kämmt, wobei die Saugkammer des Rotationscylinders von der Druckkammer durch ein in dem Gehäusedeckel g verstellbar gelagertes Segmentstück η getrennt ist, so dafs bei Drehung des Kolbens / in der Pfeilrichtung (Fig. 3) die Zahnlücken sich auf der Saugseite mit der durch die Säugöffnung h eintretenden Flüssigkeit füllen, welch letztere beim Weitergang von Kolben / und Cylinder / durch das Segmentstück in den Zahnlücken eingeschlossen und somit nach der Druckseite befördert wird, um hier durch die gegenseitig wieder in die Zahnlücken eintretenden Zähne verdrängt und in das Druckrohr c geprefst zu werden. x The internally toothed rotary cylinder / rotates concentrically in the pump housing b , with which a toothed delivery piston / attached to the drive shaft m , which is arranged eccentrically to it, meshes, the suction chamber of the rotary cylinder being separated from the pressure chamber by a segment piece η adjustably mounted in the housing cover g , so that when the piston / in the direction of the arrow (Fig. 3) is rotated, the tooth gaps on the suction side are filled with the liquid entering through the suction opening h , the latter being enclosed in the tooth gaps and thus as the piston / and cylinder / continues through the segment piece is conveyed to the pressure side in order to be displaced here by the teeth that mutually re-enter the tooth gaps and to be pressed into the pressure tube c.

Hierbei kommt als hauptsächlichstes Dichtungsmittel nur das Segmentstück η in Frage, welches infolge seiner Kürze nur sehr geringe Reibung verursacht und durch einfaches Verstellen der Schraube s im Deckel g von aufsen her bei etwa eingetretenem Verschleifs, ohne eine wesentlich gröfsere Reibung zwischen Kolben / und Cylinder/ zu verursachen, nachgestellt werden kann. The only possible sealing means here is the segment piece η , which due to its shortness causes only very little friction and by simply adjusting the screw s in the cover g from the outside in the event of any wear and tear, without significantly greater friction between the piston / and cylinder / to cause, can be readjusted.

Claims (1)

Patent-Anspruch:Patent claim: Kapselwerk mit innen verzahntem Kolbenpaar, dadurch gekennzeichnet, dafs die Saugkammer h der Pumpe von der Druckkammer c durch das Segmentstück η abgedichtet wird und dieses bei eingetretener Abnutzung der dichtenden Flächen zur Wiederherstellung der Dichtung nachgestellt werden kann.Capsule mechanism with internally toothed pair of pistons, characterized in that the suction chamber h of the pump is sealed from the pressure chamber c by the segment piece η and this can be readjusted to restore the seal when the sealing surfaces are worn.
