Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer unrtinden Sieueröffnung im Zylinder einer Einspritzpumpe für Brennkraftmaschinen.The invention relates to a method of making a There is an opening in the cylinder of an injection pump for internal combustion engines.

Die Aufgabe der Erfindung besteht darin, ein Verfahren zu entwickeln, mit dessen Hilfe die= Steueröffnung in den Pumpenzylindern in einfacher Weise mit ausreichender Genauigkeit eingearbeitetwerden kann. Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß die Steueröffnung von außen mittels eines Scheibenfräsers eingearbeitet wird. Gegenüber der sonst üblichen Ausarbeitung der Schlitze mittels Fingerfräser, bei der es meist sehr schwierig und zeitraubend ist, ein Verlaufen des F räsers zu verhindern und vorschriftsmäßig und glatt verlaufende Steuerkanten zu erzielen, hat das erfindungsgemäße Verfahren den Vorzug, bei Gewährleistung größtmöglicher Genauigkeit wesentlich einfacher zu sein. In der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargestellt.The object of the invention is to develop a method with the help of which the = control opening in the pump cylinders in a simple manner sufficient accuracy can be incorporated. This object is achieved according to the invention in that the control opening is incorporated from the outside by means of a side milling cutter will. Compared to the usual preparation of the slots using an end mill, in which it is usually very difficult and time-consuming, the milling cutter getting lost to prevent and to achieve smoothly running control edges in accordance with regulations, the method according to the invention has the advantage of being as great as possible with guarantee Accuracy to be much easier. In the drawing is an embodiment of the invention shown for example.

Abb. 2 stellt einen Scliuitt l1-11 durch den Pumpenzylinder nach Abb. 1 (lau.: 1b1). t shows the pump cylinder of an injection pump in longitudinal section: . ' Fig. 2 shows a section 11-11 through the pump cylinder according to Fig. 1 (lukewarm.

Der in Abb. t gezeigte Pumpenzylinder einer Ein-; spritzpumpe weist eine geneigt zur Zylinderlängsachse verlaufende Steueröffnung 2 auf, die, wie in Abb. 2 angedeutet, mittels eines Scheibenfräsers mit dem Radius r hergestellt wurde.The pump cylinder shown in Fig. T of a single; syringe pump points an inclined to the cylinder longitudinal axis control opening 2, which, as in Fig. 2 indicated, was produced by means of a side milling cutter with the radius r.
