Description

Mit einem Lufteinlaßventil vereinigte Kraftstoffeinspritzpumpe Es ist bekannt, ein Lufteinlaßventil für Brennkraftmaschinen mit :einer Kraftstoffeinspritzpump;e zu vereinigen.Fuel injection pump Es associated with an air intake valve it is known an air intake valve for internal combustion engines comprising: a fuel injection pump; e to unite.

Gemäß der Erfindung wird das mit der Kraftstoffeinspritzpumpe vereinigte Lufteinlaßventil in der Weise .ausgeführt, daß der Kolbejn. der Kraftstoffpumpe einen Fortsatz des Ventiltellers bildet und mit dem Ventilteller aus ,einem Stück besteht und der Zylinder der Kraftstoffpumpe mit dem Verschlußflansch des Einlaßventilgehäuses vereinigt ist.According to the invention, this is combined with the fuel injection pump Air inlet valve. Executed in such a way that the piston. the fuel pump forms an extension of the valve disk and forms one piece with the valve disk consists and the cylinder of the fuel pump with the sealing flange of the inlet valve housing is united.

Der Hub des Luftventils und damit auch der Hub des mit dem Ventil verbundenen Kraftstoffpumpenkolbens wird durch Verschiebung eines Schwinghebels geregelt, der in an sich bekannter Weise den Hub des Antriebnockens auf den Ventilstößel überträgt-Bei bekannten Brennstoffpumpen dieser Art arbeitet der hohle Luftventilschaft, der als Brennstoffpumpenzylinder ausgebildet ist, auf den feststehenden. Kolben. Das fördernde Brennstoffauslaßventil ist dabei im Luftventilteller angeordnet. . Durch die hohe Erwärmung des: Luftventilbellers am Brennraum der Brennkraftmaschine wird das sichere Arbeiten des Brennstoffauslaßventils unsicher. -. Der Luftventilsteuerungsmechanismus ist bei der bekannten Ausführung im Luftzuführungsrohr und in der Ventilkammer .angeordnet. Durch Undichtigkeiten der Brennstoffpumpe kann bewirkt werden, daß der Mechanismus entölt wird- und fressen kann. Ferner erfolgt bei der bekannten Ausführung der Druckhub, der Brennstoffpumpe beim Schließen des Luftventils durch die Luftventilfeder. Dadurch: ist das genaue Arbeiten der Brennstoffpumpe nicht gewährleistet. Bei ungenauem Arbeiten derselben kann aber die Gasmischbildung im Verbrennungsraum der Kraftmaschine ungleichmäßig werden.The stroke of the air valve and thus also the stroke of the valve connected fuel pump piston is moved by moving a rocker arm regulated, the stroke of the drive cam on the valve stem in a known manner transmits - In known fuel pumps of this type, the hollow air valve stem works, which is designed as a fuel pump cylinder, on the stationary. Pistons. The conveying fuel outlet valve is arranged in the air valve plate. . Due to the high heating of the: air valve bell in the combustion chamber of the internal combustion engine the safe operation of the fuel outlet valve becomes unsafe. -. The air valve control mechanism is in the known design in the air supply pipe and in the valve chamber. Leakage in the fuel pump can cause the mechanism is de-oiled and can eat. Furthermore, in the known design, the pressure stroke takes place, the fuel pump when the air valve is closed by the air valve spring. Through this: the exact operation of the fuel pump is not guaranteed. In the case of imprecise work but the same can cause the gas mixture to form unevenly in the combustion chamber of the engine will.

Diese Mängel der bekannten Bauart werden durch die vorliegende neue Konstruktion beseitigt. In der Zeichnung ist nur eine praktische Verkörperung der Erfindung gezeigt, die zur Erläuterung dient, die Erfindung wird aber nicht .auf diese Ausführungsform beschränkt. In der Zeichnung ist ,eine Seitenansicht mit einem teilweisen Schnitt durch die Luftventilkammer, Einspritzpumpenzylnder mit Ventilen und Verschlußfjansch dargestellt.These shortcomings of the known design are addressed by the present new one Construction eliminated. In the drawing there is only a practical embodiment of the Invention shown, which serves to explain, but the invention is not .auf this embodiment is limited. In the drawing is a side view with a partial cut through the air valve chamber, injection pump cylinder shown with valves and locking flange.

In einem Kurbelgehäuse oder Zylinder ist das Luffieinlaßventil 18 in an sich bekannter Weise .angeordnet. -Ein Fortsatz i 8a des Ventiltellers 18 bildet den Kolben für die Kraftstoffeinspritzpumpe 31 und besteht mit dem Ventilteller 18 aus einem Stück. Der Zylinder der Kraftstoffpumpe 31 mit dem Verschlußfiansch 31a ist mit dem Einlaßventilgehäuse 16 vereinigt. Das Öffnen des Lufteinla.ßven.-tils 18 und der Druckhub in der Kraftstoffpumpe 31 und gleichzeitigen öffnen des Kraftstoffauslaßventils 32 erfolgt durch eine auf der Welle 2 angeordnete Noekenscheibe 26, dagegen wird das Schließen des Lufteinlaßventils 18 und damit die Saugbewegung des mit dem Ventil aus einem Stück bestehenden Kolbens 18" durch eine Feder betätigt.Luffie inlet valve 18 is located in a crankcase or cylinder arranged in a manner known per se. -An extension i 8a of the valve disk 18 forms the piston for the fuel injection pump 31 and exists with the valve disk 18 from one piece. The cylinder of the fuel pump 31 with the closure flange 31a is united with the intake valve housing 16. Opening the air inlet valve 18 and the pressure stroke in the fuel pump 31 and at the same time opening the fuel outlet valve 32 is carried out by a Noek disc 26 arranged on the shaft 2, on the other hand the closing of the air inlet valve 18 and thus the suction movement of the valve one-piece piston 18 "actuated by a spring.

Bei Undichtigkeiten der Pumpe tropft der Kraftstoff auf den Ventilteller 18. Der Leckkraftstoff wird durch den durch das geöffnete Luftventil eintretenden Luftstrahl vergast und der Bxennkraftmaschine zugeführt. Der Hub des Lufteinlaßventils 18 und damit auch der Hub des mit dem Ventil verbundenen Brennstoffpumpenkolbens 18" wird durch Verschiebung eines Schwinghebels 35 geregelt, welcher den Hub des Antriebnockens 26 auf den Ventilstößel überträgt. Zur Verschiebung ,des Schwinghebels 3 5 ist dieser an einer drehbaren Scheibe 28 angelenkt, die mittels Ces Stellhebels 28" gedreht werden kann.If the pump leaks, the fuel drips onto the valve disk 18. The leak fuel is gasified by the air jet entering through the open air valve and fed to the engine. The stroke of the air inlet valve 18 and thus also the stroke of the fuel pump piston 18 ″ connected to the valve is regulated by moving a rocker arm 35 which transfers the lift of the drive cam 26 to the valve tappet. To move the rocker arm 35, it is on a rotatable disk 28 hinged, which can be rotated by means of Ces adjusting lever 28 ".
