Abstract

Die stetig höher werdenden Kraftstoffförderdrücke bei Einzeleinspritzpumpen erfordern Maßnahmen zur fortdauernden Gewährleistung der Betriebssicherheit. So ist es erforderlich, die Kraftstoffzuführung in dem Pumpenzylinder von genau gegenüberliegenden Seiten quer zur Bewegungsrichtung des Pumpenplungers in den Pumpenhochdruckraum (15) einmünden zu lassen. Dadurch wird eine gleichmäßige Belastung insbesondere des Pumpenplungers, beispielsweise bei dem Absteuervorgang, erreicht.The steadily increasing fuel delivery pressures in single injection pumps require ongoing warranty measures operational safety. So it is necessary to add fuel in the pump cylinder from exactly opposite Sides transverse to the direction of movement of the pump plunger to open into the high pressure pump chamber (15). Thereby there is an even load, especially on the pump plunger, for example in the control process.

Erfindungsgemäß ist der zweite Kraftstoffleitungsanschluss (7b) über eine weitere Leitungsverbindung (16c,16d) mit einem dritten Kraftstoffleitungsanschluss (7c) verbunden. Durch diese Ausbildung ist mit geringem Aufwand eine wesentlich verbesserte Möglichkeit des Anschlusses und der Verlegung der Kraftstoffleitungen (11a,11b) möglich. Hierbei ist alternativ vorgesehen, den ersten und den dritten Kraftstoffleitungsanschluss (7a,7c) nebeneinanderliegend an der Einzeleinspritzpumpe (2) oder aber koaxial zueinander am ersten Kraftstoffleitungsanschluss (7a) anzuordnen.

Figure 00000001
According to the invention, the second fuel line connection (7b) is connected to a third fuel line connection (7c) via a further line connection (16c, 16d). This design enables a significantly improved possibility of connecting and laying the fuel lines (11a, 11b) with little effort. As an alternative, the first and third fuel line connections (7a, 7c) are arranged side by side on the single injection pump (2) or coaxially with one another on the first fuel line connection (7a).
