Title (EN) FUEL INJECTOR
(FR) INJECTEUR DE CARBURANT
(DE) KRAFTSTOFFINJEKTOR
Abstract:
(EN) The invention relates to a fuel injector (10) for assembling into a receiving opening (106) of a cylinder head (100), comprising a valve housing (11), in which an interior (6) is formed that can be filled with liquid fuel. Additionally, the exterior of the valve housing (11) is equipped with a double groove (16), in which at least one sealing ring (15) is arranged in order to seal the receiving opening (106) of the cylinder head (100). The double groove (16) comprises a first groove (29) and a second groove (30), wherein an elevation (28) is arranged between the first groove (29) and the second groove (30). Furthermore, the first groove (29) has a first groove base (35), and the second groove (30) has a second groove base (36), said first groove base (35) and second groove base (36) having a conical shape.
(FR) L'invention concerne un injecteur de carburant (10) destiné à être monté dans une ouverture de logement (106) d'une culasse (100), ledit injecteur comprenant un corps d'injecteur (11) dans lequel est réalisé un espace intérieur (6) pouvant être rempli de carburant liquide. En outre, une double gorge (16), dans laquelle est disposé au moins un joint torique (15) destiné à assurer l’étanchéité de l'ouverture de logement (106) de la culasse (100), est réalisée sur une face extérieure du corps d'injecteur (11). La double gorge (16) comprend une première gorge (29) et une seconde gorge (30), une partie en saillie (28) étant formée entre la première gorge (29) et la seconde gorge (30). Par ailleurs, la première gorge (29) comporte un premier fond de gorge (35) et la seconde gorge (30) comporte un second fond de gorge (36), le premier fond de gorge (35) et le second fond de gorge (36) étant de forme conique.
(DE) Kraftstoffinjektor (10) zum Einbau in eine Aufnahmeöffnung (106) eines Zylinderkopfs (100), mit einem Ventilgehäuse (11), in dem ein Innenraum (6) ausgebildet ist, welcher mit flüssigem Kraftstoff befüllbar ist. Weiterhin ist an einer Außenseite des Ventilgehäuses (11) eine Doppelnut (16) ausgebildet, in der mindestens ein Dichtring (15) zur Abdichtung der Aufnahmeöffnung (106) des Zylinderkopfs (100) angeordnet ist. Die Doppelnut (16) umfasst eine erste Nut (29) und eine zweite Nut (30), wobei zwischen der ersten Nut (29) und der zweiten Nut (30) eine Erhebung (28) angeordnet ist. Außerdem weisen die erste Nut (29) einen ersten Nutgrund (35) und die zweite Nut (30) einen zweiten Nutgrund (36) auf, welcher erster Nutgrund (35) und welcher zweiter Nutgrund (36) konisch ausgebildet sind.
