Abstract

Bei der Produktion von Kraftstoffeinspritzpumpen (10) führen ferti­ gungsbedingte Teiletoleranzen von Elementen des Drehzahlreglers in der Leerlaufposition zu unterschiedlichen Kraftstoffzumessungen in diesem Betriebszustand.
Durch eine von außerhalb des Gehäuses (11) der Kraftstoffeinspritz­ pumpe (10) vornehmbaren Einstellung ist es möglich, diese Teiletole­ ranzen durch Verstellungen am Drehzahlregler zu eliminieren, ohne dessen Innenverhältnisse zu verfälschen.
