Description

  

      Treibstoffeinspritzpumpenanlage    mit mehreren, gleichachsig im Kreise angeordneten  Einzelpumpen und mit Treibstoffreiniger.    Die vorliegende Erfindung bezieht sich  auf     Treibstoffeinspritzpumpenanlagen    mit meh  reren, gleichachsig im greise angeordneten  Einzelpumpen und betrifft die Anordnung  eines Treibstoffreinigers, der die Aufgabe hat,  aus dem Treibstoff gasförmige oder feste  Fremdstoffe vor dem Eintritt in die Saug  räume der Pumpen abzuscheiden. Bei der  artigen Pumpen wurde der Reiniger bisher  von der Pumpe getrennt angeordnet, oder am  Pumpengehäuse aussen angesetzt, was einer  seits leicht zu Beschädigungen des Reinigers  führen kann und anderseits eine einfache und  geschlossene Formgebung der Pumpenanlage  unmöglich macht.

   Gemäss der Erfindung wer  den diese Nachteile dadurch vermieden, dass  der     Treibstoffreiniger    in einem von den Einzel  pumpen umschlossenen Raum des Pumpen  gehäuses angeordnet ist.  



  In der Zeichnung ist in einem Aufriss ein  Ausführungsbeispiel der Treibstoffeinspritz-         pumpenanlage    gemäss der Erfindung darge  stellt, in der als     Treibstoffreiniger    ein Ent  lüfter eingebaut ist.  



  In dem Pumpengehäuse 1 sind z. B. sieben  Einzelpumpen gleichachsig im     greise    ange  ordnet. Im Zylinder 2 einer solchen Pumpe  ist ein     Kolben    3 geführt, der über eine in  der Zeichnung nicht sichtbare Antriebsein  richtung durch eine Welle 4 betätigt wird.  Bei jeder Pumpe ist ausserdem ein Druck  ventil 5 vorgesehen, sowie ein     Anschluss-          nippel    6 für die Druckleitung 7.  



  Im Innern des Pumpengehäuses 1, la ist  in dem von den Einzelpumpen umschlossenen  Hohlraum 12 ein Entlüfter<B>13</B> angeordnet.  Ein Deckel 14 schliesst den Raum 12 ab und  dient gleichzeitig zur Befestigung des Ent  lüfters. Der Treibstoff wird durch die Lei  tung 15 in einen Vorraum 16 und von hier  aus durch die ringförmige Öffnung 17 in den  Entlüfter 13 geleitet, wo die im Treibstoff      enthaltene Luft und andere gasförmige Stoffe  ausgeschieden werden. Der gereinigte Treib  stoff verlässt den Entlüfter durch die Öffnung  18 und tritt in den Hohlraum 12, aus dem  er durch Bohrungen 19 den Saugräumen 20  der Einzelpumpen zufliesst. Die aus dem Treib  stoff ausgeschiedene Luft oder dergleichen  wird durch die Leitung 21, 22 abgeführt.



      Fuel injection pump system with several single pumps arranged on the same axis in a circle and with a fuel cleaner. The present invention relates to fuel injection pump systems with several coaxially arranged single pumps and relates to the arrangement of a fuel cleaner, which has the task of separating gaseous or solid foreign substances from the fuel before entering the suction chambers of the pumps. In the case of such pumps, the cleaner was previously arranged separately from the pump, or attached to the outside of the pump housing, which on the one hand can easily damage the cleaner and on the other hand makes a simple and closed design of the pump system impossible.

   According to the invention, these disadvantages are avoided in that the fuel cleaner is arranged in a space in the pump housing that is enclosed by the individual pumps.



  In the drawing, an embodiment of the fuel injection pump system according to the invention is shown in an elevation, in which a vent is installed as a fuel cleaner.



  In the pump housing 1, for. B. seven single pumps coaxially arranged in old age. In the cylinder 2 of such a pump, a piston 3 is guided, which is actuated by a shaft 4 via a drive device not visible in the drawing. Each pump also has a pressure valve 5 and a connection nipple 6 for the pressure line 7.



  In the interior of the pump housing 1, la, in the cavity 12 enclosed by the individual pumps, a vent <B> 13 </B> is arranged. A lid 14 closes the space 12 and is used at the same time to attach the Ent fan. The fuel is passed through the Lei device 15 into an antechamber 16 and from here through the annular opening 17 into the ventilator 13, where the air and other gaseous substances contained in the fuel are excreted. The cleaned propellant leaves the ventilator through the opening 18 and enters the cavity 12, from which it flows through holes 19 to the suction chambers 20 of the individual pumps. The excreted from the propellant air or the like is discharged through line 21, 22.
