Description

Pumpe. Das Patent betrifft eine Ergänzung zum Patent 419o35. Das Neue besteht darin, daß der eine Aren des den, Kolben, antreibenden Doppelhebels zwischen zwei am freien Ende des Kolbens angeordnete Rollen greift und der andere. Arm unter Wirkur; einer Feder steht. Dies eingibt einen wesentlichen Fortschritt, da dadurch der Kolben genau, geradlinig, ahne jedes Spiel, hin und her bewegt wird.Pump. The patent relates to a supplement to the 419o35 patent. The new consists in the fact that one type of the double lever driving the piston is between two rollers arranged at the free end of the piston engages and the other. Arm under Effect; a spring stands. This enters a significant advance as it does the piston is moved back and forth precisely, in a straight line, suspecting any play.

Auf der Zeichiiang ,ist eine Ausführungsform des Erfindutresgegenstandes dargestellt. Abb. i zeigt die Pumpe von oben gesehen. Abb. z zeigt den Längssclimitt C-D nach Abb. i.On the drawing is an embodiment of the subject matter of the invention shown. Fig. I shows the pump seen from above. Fig. Z shows the longitudinal climate C-D according to Fig. I.

Abb. 3 der Zeichnung stellt den Schnitt A-B der Draufsicht (Abb. a) dar.Fig. 3 of the drawing represents section A-B of the top view (Fig. A) represent.

Der Dappelheb-el i ist schwenkbar im Drehpunkt il des Gehäuses a gelagert. Der einte Arm dieses Doppelhebelsi greift zwischen zwei am freien Ende des Kolbens b angeordnete Rollen h, die im Kolbenschlitz drehbar @gelagert sind. Das andere Armende steht unter Wirkung der Feder k o. dgl. Die Anordnung des Doppelhebels i bewirkt beim Auf- und, Niedergehen desselben ein fast reibungsloses und( vollkommen gerades Anheben des Kolbens b, was zur Folge hat, daß dieser der geringsten, Abnutzung unterworfen ist und lange druckdicht hält.The pivot lever i is pivotably mounted in the pivot point il of the housing a. The one arm of this double lever engages between two at the free end of the piston b arranged rollers h, which are rotatably mounted in the piston slot. The other The end of the arm is under the action of the spring k or the like. The arrangement of the double lever i causes an almost frictionless and (perfect straight lifting of the piston b, with the result that this one of the least, wear is subject to and holds pressure-tight for a long time.

Die Anordnung der Feder kann auch so vorgesehen sein, da.ß diese auf Druck beansprucht wird, wodurch ein etwaiges Zerreißen der Feder im Betriebe vermieden wird. Ferner laufen alle diese beweglichen gehärteten Teile in einem abgeschlossenen Ölbade im Pumpengehäuse, wodurch eine Abnutzung derselben fast ausgeschlossen ist.The arrangement of the spring can also be provided so that it opens Pressure is stressed, which avoids possible tearing of the spring in operation will. Furthermore, all of these movable hardened parts run in a locked one Oil bath in the pump housing, which means that wear and tear of the same is almost impossible.
