Title (DE) KRAFTSTOFFINJEKTORANORDNUNG
(EN) FUEL INJECTOR ARRANGEMENT
(FR) SYSTÈME D'INJECTION DE CARBURANT
Abstract:
(DE) Kraftstoffinjektoranordnung (1) aufweisend: - ein hydraulisches Injektor-Steuersystem (17), - eine Brenngas-Dosierventil-Baugruppe (37) mit einem Düsenventilglied (35); - ein hydraulisches Dichtungssystem (49), welches an das hydraulische Injektor- Steuersystem (17) kommunizierend angebunden ist und mittels welchem an dem Düsenventilglied (35) eine Sperrfluiddichtung (51 ) gebildet wird; und - ein Sicherheitsventil (65) in einem Brenngas- Versorgungsweg (43) für die Brenngas- Dosierventil-Baugruppe (37), welches mittels eines Hydraulikdruckes im hydraulischen Dichtungssystem (49) gesteuert wird.
(EN) Fuel injector arrangement (1) having: - a hydraulic injector control system (17), - a combustion gas metering valve assembly (37) with a nozzle valve member (35); - a hydraulic seal system (49) which is attached in a communicating manner to the hydraulic injector control system (17) and by means of which a barrier fluid seal (51) is formed at the nozzle valve member (35); and - a safety valve (65) in a combustion gas supply path (43) for the combustion gas metering valve assembly (37) which is controlled by means of a hydraulic pressure in the hydraulic seal system (49).
(FR) L'invention concerne un système d'injection de carburant (1) présentant : un système hydraulique de commande d'injecteur (17); un module soupape de dosage (37) du gaz de combustion muni d'un élément soupape d'injecteur (35); un système d'étanchéité hydraulique (49) qui est en communication avec le système hydraulique de commande d'injecteur (17) et par lequel une étanchéité à fluide tampon (51) est formée sur l'élément soupape d'injecteur (35); et une soupape de sûreté (65) sur un trajet d'alimentation (43) en gaz de combustion pour le module soupape de dosage (37) du gaz de combustion, laquelle est commandée au moyen d'une pression hydraulique présente dans le système d'étanchéité hydraulique (49).
