Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung'betrifft einen Antrieb für kleinere Förderpumpen, wie sie für Schmiereinrichtungen oder zur Brennstoffzuführung u. dgl. benutzt werden, bei welchen sowohl die KoI-benbewegung als auch die Steuerbewegung zwangläufig ist und eine Hubregelung von Null bis zum Maximum ausgeführt werden kann.The invention relates to a drive for smaller ones Feed pumps such as those used for lubrication systems or for fuel supply and the like. be used in which both the piston movement and the control movement is inevitable and a stroke control from zero to the maximum can be carried out.

Gemäß der Erfindung wird sowohl der Antrieb des Kolbens als auch der des Steuerschiebers mit einem einzigen Exzenter bewirkt, an dem unter 90° zueinander versetzt zwei Hebel angeordnet sind, von denen der eine in einen bezüglich seiner Größe verstellbaren Schlitz im Kolbenkörper eingreift, während der zum Antrieb des Schiebers dienende Hebel hinter einer drehbar gelagerten Gleitführung ebenfalls durch ein Auge an der Schieberstange geführt ist.According to the invention, both the drive of the piston and that of the control slide caused with a single eccentric, offset at 90 ° to each other two levers are arranged, one of which is adjustable in size Slot in the piston body engages, while the one used to drive the slide Lever behind a rotatably mounted sliding guide also through an eye on the Slide rod is guided.

Die beiliegende Zeichnung veranschaulicht ein Ausführungsbeispiel, und zwar zeigt:The accompanying drawing illustrates an embodiment, namely shows:

Fig. ι die Pumpe von der Seite teilweise im Schnitt,Fig. Ι the pump from the side partially in section,

Fig. 2 von der Seite gesehen mit geschnittenem Zylinder.Fig. 2 seen from the side with a cut cylinder.

Fig. 3 bis 6 zeigen verschiedene Stellungen der Pumpe.3 to 6 show different positions of the pump.

λ ist der Zylinderkörper, der sowohl dieλ is the cylinder body that contains both the

Kolbenbohrung als auch senkrecht dazu verlaufend den Schieberkanal d besitzt. c ist der Kolbenkörper und b der Steuerschieber.Piston bore as well as running perpendicular to it has the slide channel d . c is the piston body and b is the control slide.

e ist das gemeinsame Exzenter mit den um 90° versetzten Antriebshebeln f und g. Der Hebel g greift in den Schlitz h ein, der durch die Schraube i in seiner Länge verstellbar ist. k ist eine drehbare Gleitführung für den Hebel f, der in das Auge I an dem Schieber c eingreift. Bei Drehung des Exzenters e schwingen die Hebel f, g um die Gleitführung k. Dabei beschreiben die Enden der Hebel Kurven. Der Schieberweg entspricht nun der Projektion dieser Kurve, während der Kolben seinen Weg in der Zeit zurücklegt, in der der Hebel b die andere Kurve beschreibt. e is the common eccentric with the drive levers f and g offset by 90 °. The lever g engages in the slot h , which can be adjusted in length by the screw i. k is a rotatable sliding guide for the lever f, which engages in the eye I on the slide c. When the eccentric e rotates, the levers f, g swing around the sliding guide k. The ends of the levers describe curves. The slide travel now corresponds to the projection of this curve, while the piston covers its path in the time in which the lever b describes the other curve.

Die ganze Anordnung läßt sich naturgemäß noch in der verschiedensten Art und Weise ausbilden.The whole arrangement can of course still be in the most varied of ways Train wise.
