Description
Brennstofeinspritzpumpe für Brennkraftmaschinen . Zusatz zum Patent 66o ggo Die vorliegende Erfindung betrifft eine besonders vorteilhafte und zweckmäßige Aus-. bildung des Einsatzkörpers für die Ventile bei der im Hauptpatent 66o 99o beschriebenen Brennstoffeinspritzpumpe; diese Ausbildung ermöglicht im Zusammenhang mit der im Hauptpatent enthaltenen Anordnung des Saugventils eine fast vollständige Herstellung des Einsatzkörpers auf selbsttätig arbeitenden Werkzeugmaschinen, wodurch die Herstellungskosten wesentlich vermindert werden. Diese Vorteile werden erfindungsgemäß dadurch erreicht, daß der das Druck- und das Saugventil enthaltende Einsatzkörper in einer zwischen diesen beiden Ventilen liegenden, zur Achse des Körpers senkrechten Ebene in zwei mit ebenen Stirnflächen aneinanderstoßende Teile geteilt ist.Fuel injection pump for internal combustion engines. Addition to the patent 66o ggo The present invention relates to a particularly advantageous and expedient one The end-. Formation of the insert for the valves in the main patent 66o 99o fuel injection pump described; this training enables related with the arrangement of the suction valve contained in the main patent an almost complete Production of the insert body on automatically working machine tools, whereby the manufacturing costs are significantly reduced. These advantages are according to the invention achieved in that the insert body containing the pressure and suction valve in one lying between these two valves and perpendicular to the axis of the body Level is divided into two parts abutting with flat end faces.
Der weiteren Erfindung gemäß ist es .dabei zweckmäßig, wenn die Führungsbohrung des Saugventilschaftes ohne Unterbrechung in die. Führungsbohrung des Druckventilschaftes übergeht und der Saugventilschaft in seiner ganzen Länge durchbohrt ist, so daß der Pumpenarbeitsraum durch den .durchbohrten Saugventilschaft mit dem- Vorraum des Druckventils in Verbindung steht. Diese Ausbildung bringt eine wesentliche Vereinfachung der Kanalführung im Einsatzkörper mit sich. In der Zeichnung sind -zwei -Ausführungsbeispiele des Erfindungsgegenstandes, in Verbindung mit der im Hauptpatent dargestellten Brennstoffeinspritzpumpe in schematischer. Weise dargestellt, und zwar zeigen: Abb. i eine Anordnung mit seitlicher Druckleitung und Abb.2 eine solche mit zentraler Druckleitung.According to the further invention, it is expedient if the guide bore of the suction valve stem without interruption in the. Guide bore of the pressure valve stem passes and the suction valve stem is pierced in its entire length, so that the pump working space through the .perforated suction valve stem with the antechamber of the pressure valve is in communication. This training brings a significant simplification the channel guide in the insert body with it. In the drawing there are two exemplary embodiments of the subject matter of the invention, in connection with the fuel injection pump shown in the main patent in schematic. Represented way, namely show: Fig. I an arrangement with lateral pressure line and Fig. 2 one with a central pressure line.
Der. im Ausführungsbeispiel des `Hauptpatentes gezeigte Einsatzkörper 15 ist erfindungsgemäß durch eine zur Achse des Körpers senkrechte Ebene in zwei mit ebenen Stirnflächen aneinanderstoßende Teile i 5a und i 5L geteilt. Der Teil i 5a .:enthält das Saugventil i7; zwischen dem Zylinder und dem Saugventilgehäuse ist die durchbrochene Platte 22 als Widerlager für die Ventilschließ= feder 18 und als Anschlag zur Hubbegrenzung ' des Ventils angeordnet. Der Raum 3 i oberhalb des Ventilsitzes ist durch mehrere Bohrungen i9. mit dem Saugraum 2o verbunden. Neben dem Saugventil führen eine odermehrere Leitungen 32 von dem Pumpenarbeitsraum zu der oberen Stirnfläche des Saug-, ventilgehäuses. Das Druckventilgehäuse i 5b ist mit einer Bohrung 3q. versehen, welche die Leitung 32 mit dem Vorraum 35 des Druckventils fq: verbindet. Die übereinstimmung der beiden Leitungen wird zweckmäßig durch einen Päßstift 36 gesichert, wodurch - gegenüber der üblichen . Bauart mit Ringnut der. schädliche Raum der Pumpe wesentlich mindert wird. Oberhalb des Druckventi,Igie- E häuses befindet sich die überwurfmutter,, welche in den Pumpenkörper 9 mittels eines Gewindes eingesetzt ist; durch Anziehen dieser Mutter worden der Pumpenzylinder und die beiden Ventilgehäuse aüfeinandergepreßt und durch eine Dichtung 37 nach außen abgedichtet. An der überwurfmutter 16 wird eine nicht näher gezeigte Druckleitung in bekannter Weise "angeschlossen.Of the. Insert body shown in the embodiment of the `main patent 15 is according to the invention in two by a plane perpendicular to the axis of the body with flat end faces abutting parts i 5a and i 5L divided. The part i 5a .: contains the suction valve i7; between the cylinder and the suction valve housing is the perforated plate 22 as an abutment for the valve closing = spring 18 and arranged as a stop to limit the stroke 'of the valve. The room 3 i above the The valve seat is through several holes i9. connected to the suction chamber 2o. Next to one or more lines 32 lead from the pump working space to the suction valve the upper face of the suction, valve housing. The pressure valve housing i is 5b with a hole 3q. provided, which the line 32 with the antechamber 35 of the pressure valve fq: connects. Agreement of the two lines is appropriate secured by a pin 36, whereby - compared to the usual. Type with Ring groove of the. harmful space of the pump is significantly reduced. Above the pressure valve, Igie E housing is the union nut ,, which in the pump body 9 by means a thread is inserted; by tightening this nut became the pump cylinder and the two valve housings are pressed together and through a seal 37 sealed on the outside. A pressure line, not shown in detail, is attached to the union nut 16 in a known way "connected.
Die in Abb.2 dargestellte Bauart ermöglicht eine weitere Vereinfachung .der Kanalführung in den beiden Ventilgehäusen und unterscheidet sich von der beschriebenen Ausführungsform dadurch, daß der Schaftdes Saugventils eine durchgehende Längsbohrung 38 aufweist und zur Weiterleitung des geförderten Brennstoffes benutzt wird; in diesem Fall ist auch das Druckventilgehäuse in seiner ganzen Länge durchbohrt, wodurch eine unmittelbare Verbindung zwischen Saug-und Druckventil geschaffen ist. Neben der. einfachen Bearbeitungsmöglichkeit der Ventilehäuse kann bei dieser Ausführung auch der Ü hädliche Raum der Pumpe auf ein Minstmaß verkleinert werden.The design shown in Fig.2 enables a further simplification of the duct routing in the two valve housings and differs from the embodiment described in that the shaft of the suction valve has a continuous longitudinal bore 38 and is used to pass on the fuel being pumped; in this case the pressure valve housing is also drilled through over its entire length, creating a direct connection between the suction and pressure valves. In addition to the. simple editing possibility of Ventilehäuse can also Ü hädliche space be reduced pump to a Minstmaß in this embodiment.
