Description

Rundlaufpumpe als Brennstoffeinspritzpumpe für mehrzylindrige Brennkraftmaschinen, insbesondere für Dieselmotoren Die Erfindung bezieht sich auf die Ausbildung einer Rundlaufpumpe als Brennstoffeinspritzpumpe für mehrzylindrige Brennkraftmaschinen, insbesondere für Dieselmotoren. Die Erfindung bezweckt, den Brennstoff für jeden Zylinder mit einfachen Mitteln so genau zu dosieren, daß gleiche Zylinderleistung erreicht wird.Rotary pump as a fuel injection pump for multi-cylinder internal combustion engines, especially for diesel engines The invention relates to the formation of a Rotary pump as a fuel injection pump for multi-cylinder internal combustion engines, especially for diesel engines. The invention aims to provide fuel for everyone Dose cylinders so precisely with simple means that the same cylinder output is achieved.

Entsprechend der Erfindung ist in der umlaufenden Kolbentrommel nur :ein hin und her beweglicher Förderkolben radial angeordnet. Dieser gleitet mit seinem freien Ende auf einem im Pumpengehäuse angeordneten Umfangsnockenring, der die der Zylinderzahl entsprechende Anzahl von Saug- und Druckästen für die Saug- und Druckhübe trägt, die in ihrer Größe für jeden beliebigen Einspritzwinkel genau ausgeführt werden können, so daß die beschleunigte und schlagartige Brennstoffeinspritzung in ein-,vandfreierWeise bei gleichzeitig feinster Brennstoffzerstäubung auch bei Mehrzylindermaschinen mittels nur eines Kolbens erzielt wird. Die als Verteiler dienende Scheibe hat die entsprechende Anzahl von Saug- und Druckkanälen. Die mehrfachen Saug- und Druckhübe vollziehen sich also bei einem Umlauf der Kolbentrommel.According to the invention is in the rotating piston drum only : a reciprocating delivery piston arranged radially. This slides with you its free end on a circumferential cam ring arranged in the pump housing, the the number of suction and pressure branches corresponding to the number of cylinders for the suction and pressure strokes that are accurate in size for any injection angle can be carried out so that the accelerated and sudden fuel injection in one, vand-free way with at the same time the finest fuel atomization also with Multi-cylinder machines is achieved by means of only one piston. As a distributor serving disc has the corresponding number of suction and pressure channels. The multiple So suction and pressure strokes take place during one revolution of the piston drum.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Dabei zeigen: Abb. i einen Längsschnitt durch die Brennstofeinspritzpumpe, Abb. z einen Querschnitt nach A--; der Abb. i, Abb. 3 einen Querschnitt nach B-B der Abb. i und Abb. ¢ eine Ansicht auf die Regeleinrichtung der Einspritzkanalbuchsen.An exemplary embodiment of the invention is shown in the drawing. They show: Fig. I a longitudinal section through the fuel injection pump, Fig. z a cross-section according to A--; Fig. i, Fig. 3 a cross section according to B-B of Fig. I and Fig. ¢ a view of the control device of the injection channel bushings.

In dem Pumpenkörper, der aus den beiden Lagerdeckeln b, bi und dem zwischen diesen angeordneten Umfangsnockenring a besteht, liegt die Kolbentrommel e mit der Antriebswelle c'. In der Kolbentrommel c ist eine Bohrung für den Förderkolben d in der Richtung des Durchmessers vorgesehen.In the pump body, which consists of the two bearing caps b, bi and the exists between these arranged circumferential cam ring a, the piston drum lies e with the drive shaft c '. In the piston drum c is a hole for the delivery piston d provided in the direction of the diameter.

Beim Umlauf der Kolbentrommel c gleitet der unter Federdruck stehende Förderkolben an dem Umfangsnockenring a und wird entsprechend den in diesem angeordneten Saug-und Druckästen g, lt hin und her bewegt. Um ein reibungsloses Gleiten beim Umlauf des Förderkolbens d an dem Umfangsnockenring a zu erreichen, ist er mit der Laufrolle e, die in dem gabelförmigen Teil d des Kolbens d angeordnet ist, versehen.When the piston drum c rotates, the one under spring pressure slides Delivery piston on the circumferential cam ring a and is arranged in this according to the Suction and pressure branches g, lt moved back and forth. To ensure a smooth glide when To achieve circulation of the delivery piston d on the circumferential cam ring a, it is with the Roller e, which is arranged in the fork-shaped part d of the piston d, is provided.

je nach der Ausführung der Äste lt und der Einspritzkanäle h erfolgt die Brennstoffeinspritzung in den Verbrennungsraum schlagartig unter größter Beschleunigung und feinster Zerstäubung. Die Brennstoffregelung erfolgt durch Drehung der Kanalbuchsen m um ihre Achse mittels des Zahnrades o und des Hebels p-(Abb. ¢). je nach Drehung wird die nutzbare Größe der Eintrittsöffnung der Druckkanäle k verringert odervergrößert, d. h. die Brennstoffmenge geregelt und der überschüssige Brennstoff durch den überlaufkanalh' zur Saugleitung! abgeleitet.takes place depending on the design of the branches lt and the injection channels h the fuel injection into the combustion chamber abruptly with the greatest acceleration and finest atomization. The fuel is regulated by turning the duct sockets m around its axis by means of the gear wheel o and the lever p- (Fig. ¢). depending on the rotation will the usable size of the inlet opening of the pressure channels k is reduced or enlarged, d. H. the amount of fuel regulated and the excess fuel through the overflow channel to the suction line! derived.

Die Anzahl der Druck- und Saugäste h, g und der Einspritzkanäle k richtet sich nach der Zylinderzahl des Motors.The number of pressure and suction branches h, g and the injection channels k depends on the number of cylinders in the engine.

Der beim Umlauf der Kolbentrommel c an dem Umfangsnockenringa. geführte, unter Federdruck stehende Kolben d saugt die erforderliche Brennstoffmenge durch den Kanal! des Verteilers r mittels des in der Trommel c vorgesehenen Kanals q an. Der Druckast lt drückt den Förderkolben d nach innen (Druckhub) und fördert den Brennstoff mittels der verschiedenen Einspritzkanäle k und n zu den Zerstäuberdüsen der einzelnen Zylinder. Der Brennstoff wird durch die Leitungl dem Saugkanali der Pumpe zugeführt. Es bleibt der weiteren Ausführung vorbehalten, in der Kolbentrommel mehrere Brennstoffkolben nebeneinander oder gegenüberliegend so anzuordnen, daß auch Motoren mit mehr als vier Zylindern nur eine Einheitspumpe benötigen.When the piston drum c rotates on the circumferential cam ring a. guided, Piston d, which is under spring pressure, sucks in the required amount of fuel the channel! of the distributor r by means of the channel q provided in the drum c. The pressure load lt pushes the delivery piston d inwards (pressure stroke) and promotes the Fuel by means of the various injection channels k and n to the atomizer nozzles of the individual cylinders. The fuel is the Saugkanali through the line Pump supplied. It is reserved for further execution, in the piston drum to arrange several fuel pistons side by side or opposite one another so that engines with more than four cylinders only need one unit pump.

Ferner kann durch eine besondere Einrichtung der Hub des Förderkolbens, -ohne daß davon das Wesen der Erfindung beeinflußt würde, verändert werden.Furthermore, the stroke of the delivery piston, -without that the essence of the invention would be affected.
