Abstract

Es wird ein Einspritzventil für Kraftstoffeinspritzanlagen für Brennkraftmaschinen vorgeschlagen, das zur Einsprit­ zung von Kraftstoff in das Saugrohr dient. Das Einspritzventil umfaßt ein Ventilgehäuse (1) aus ferromagnetischem Mate­ rial, in dem ein als Kern dienender Anschlußstutzen (7) gehalten ist, mit dem ein Anker (14) zusammenwirkt. Mit dem Ventilgehäuse (1) ist ein Düsenkorper (9) mit einem Ventilsitz (24) verbunden, mit dem ein Dichtabschnitt (25) einer Düsennadel (17) zusammenarbeitet. Die Düsennadel (17) wird durch Führungsabschnitte (33, 34) in einer Führungsbohrung (21) des Düsenkorpers (9) geführt, wobei dur sich an den Dichtabschnitt (25) anschließende Führung­ sabschnitt (34) mit Zumeßbohrungen (43) versehen ist. Durch die Kraftstoffzumessung stromaufwärts des Ventil­ sitzes (24) wird eine Beeinträchtigung der Kraftstoffzumes­ sung durch Ablagerungen vermieden. It becomes an injection valve for fuel injection systems proposed for internal combustion engines that for injection serving of fuel in the intake manifold. The injector comprises a valve housing (1) made of ferromagnetic mate rial, in which a connecting piece serving as a core (7) is held with which an anchor (14) cooperates. With the valve housing (1) is a nozzle body (9) with a Valve seat (24) connected to which a sealing section (25) a nozzle needle (17) works together. The nozzle needle (17) by guide sections (33, 34) in one Guide bore (21) of the nozzle body (9), wherein dur leading to the sealing section (25) s section (34) is provided with metering holes (43). Fuel metering upstream of the valve seat (24) becomes an impairment of fuel solution avoided by deposits.
