Title (DE) BRENNSTOFFEINSPRITZVENTIL FÜR VERBRENNUNGSKRAFTMASCHINEN
(EN) FUEL INJECTION VALVE FOR INTERNAL COMBUSTION ENGINES
(FR) Soupape d'injection de carburant pour moteurs A combustion interne
Abstract:
(DE) Die Steuervorrichtung (52) des Brennstoff einspritzventils Weist ein pilzförmiges Zwischenventilglied (56) auf, welches mit einer Gleitpassung (58') in einer ersten Zwischenplatte (12) geführt ist. Das einen Steuerkolben (28') aufweisende Einspritzventilglied (28) zum Öffnen und Schliessen von Einspritzöffnungen zur Realisation von intermittierenden Einspritzvorgängen definiert zusammen mit einer Führungshülse (36) und der unteren Fläche (12a) der ersten Zwischenplatte (12) einen Steuerraum (54). Eine zweite Zwischenplatte (14) befindet sich zwischen der ersten Zwischenplatte (12) und dem Gehäusekörper (10) und weist einen Ventilraum (70) auf, der mit der Stirnseite des Schaftes (58) des pilzförmigen Zwischenventilgliedes (56) hydraulisch verbunden ist.
(EN) A control device (52) of a fuel injection valve has a mushroom-shaped intermediate valve member (56) which is guided with a sliding fit (58') in a first intermediate plate (12). An injection valve member (28), which has a control piston (28'), for opening and closing injection openings in order to realize intermittent injection processes defines a control space (54) together with a guide sleeve (36) and the lower face (12a) of the first intermediate plate (12). A second intermediate plate (14) is situated between the first intermediate plate (12) and a housing body (10), and has a valve space (70) which is hydraulically connected to the end side of a shank (58) of the mushroom-shaped intermediate valve member (56).
(FR) Le dispositif de commande (52) de la soupape d'injection de carburant de l'invention présente un organe intermédiaire de soupape (56) en forme de champignon guidé avec un ajustement coulissant (58') dans une première plaque intermédiaire (12). L'organe de soupape d'injection (28) qui présente un piston pilote (28') et qui sert à ouvrir et fermer des ouvertures d'injection en vue de réaliser des opérations intermittentes d'injection définit une première chambre pilote (54) avec une douille de guidage (36) et la surface inférieure (12a) de la plaque intermédiaire (12). Une deuxième plaque intermédiaire (14) est située entre la première plaque intermédiaire (12) et le corps (10) du boîtier et présente un espace de soupape (70) qui est relié à écoulement au côté frontal de la tige (58) de l'organe intermédiaire de soupape (56) en forme de champignon.
