Description
Gegenstand der Erfindung ist eine Vorpumpeinrichtung für eine Kraftstoffeinspritzpumpe, insbesondere eine Pumpe mit in V-Form zueinander angeordneten Zylindern, bei der der Vorpurnphebel bei Bedarf einsteckbar ist und am Stößel des Pumpenkolbens angreift.The invention relates to a pre-pump device for a fuel injection pump, in particular a pump with cylinders arranged in a V-shape, in which the pre-pump lever can be inserted if necessary and engages the plunger of the pump piston.
Die Erfindung besteht darin, daß die Einführungs-@ öffnung für den Vorpumphebel dem Stößel als Führung gegen Verdrehung dient. Bei der erfindungsgemäßen Einspritzpumpe wird also eine besondere Stößelführung eingespart und somit ihr Aufbau vereinfacht.The invention consists in that the introduction @ opening for the Pre-pump lever serves as a guide to prevent rotation of the plunger. In the inventive Injection pump therefore saves a special tappet guide and thus its structure simplified.
In Durchbildung der Erfindung setzt sich die Einführungsöffnung für den Vorpumphebel vom Pumpenzylinder aus in eine den Hebel seitlich führende und an ihrem Grund abstützende Kulisse fort. Bei einer Einspritzpumpe mit in V-Form zueinander angeordneten Zylindern ist zwei gegenüberliegenden Pumpenzylindern -eine einzige Kulisse zugeordnet. Tim eine Be-, schädigung der Stößelführungsbahn zu verhindern, empfiehlt es sich, den Vorpumphebel im Bereich dieser Bahn schmaler als diese zu bemessen.In an implementation of the invention, the insertion opening is used the pre-pump lever from the pump cylinder into a lever laterally leading and continue to support the backdrop. In the case of an injection pump with a V-shape mutually arranged cylinders is two opposing pump cylinders - one assigned only backdrop. Tim prevent damage to the slide guideway, it is advisable to make the priming lever narrower than this in the area of this path measured.
In der Zeichnung ist eine Ausführungsform der Erfindung in Anwendung auf eine Kraftstoffeinspritipumpe mit in V-Fonn zueinander angeordneten Pumpenzylindern beispielsweise dargestellt.In the drawing, an embodiment of the invention is in use to a fuel injection pump with pump cylinders arranged in a V-shape to one another for example shown.
Abb. i zeigt die Pumpe im Querschnitt; Abb. 2 stellt eine Draufsicht auf einen Abschnitt der Pumpe dar.Fig. I shows the pump in cross section; Fig. 2 is a top view on a section of the pump.
In Abb. i ist eine Kraftstoffeinspritzpumpe im Querschnitt gezeigt, deren Pumpenkolben von einer Nockenwelle i aus über Stößel angetrieben werden. Die Stößel sind, wie durch Stößel 2 veranschaulicht, zylindrisch ausgeführt und mittels einer Schraube 3 in einer Öffnung 4 des Pumpengehäuses verdrehungssicher geführt. Durch diese Öffnung 4 und eine dieser gegenüber im Stößel vorgesehenen Ausnehmung wird der Vorpumphebel 6 eingeführt. Dieser Vorpumphebe16 ist in einer bis zu dem in der Schnittebene gegenüberliegenden Pumpenzylinder geführten Kulisse seitlich geführt und stützt sich an deren Grund auf einem Rundstab 8 ab. Die Nase y des Hebels 6 ist schmaler als die Führungsbahn für die Schraube 3 ausgeführt, so daß eine Beschädigung dieser Bahn beim Vorpumpen vermieden wird.In Fig. I a fuel injection pump is shown in cross section, the pump pistons of which are driven by a camshaft i via tappets. the The plungers are, as illustrated by the plunger 2, designed to be cylindrical and by means of a screw 3 guided in an opening 4 of the pump housing against rotation. Through this opening 4 and a recess provided opposite this in the plunger the priming lever 6 is inserted. This Vorpumphebe16 is in one to the in the cutting plane opposite pump cylinder guided coulisse laterally guided and is supported at the bottom on a round bar 8. The nose y of the lever 6 is made narrower than the guide track for the screw 3, so that damage this path is avoided when priming.
