Title (EN) DUAL-FUEL INJECTOR
(FR) DOUBLE INJECTEUR DE CARBURANT
(DE) DUAL-FUEL-KRAFTSTOFFINJEKTOR
Abstract:
(EN) The invention relates to a dual fuel injector (1) comprising a gas injector assembly and a liquid fuel injector assembly, comprising: an injector housing (55), a clamping nut (77) which is arranged in a tensioned manner on the injector housing (55) and said housing is surrounded by a section. The invention is characterized in that a gas storage chamber (85) is arranged between the injector housing (55) and the clamping nut (77).
(FR) Double injecteur de carburant (1) pourvu d'un bloc structural d'injection de gaz et d'un bloc structural d'injection de carburant liquide, qui comporte un boîtier d'injecteur (55), et un écrou de serrage (77) disposé sur le boîtier d'injecteur (55) de manière à serrer ce dernier et à l'entourer sur un certain segment. Ledit double injecteur de carburant est caractérisé en ce qu'une cavité d'accumulation de gaz (85) est formée entre le boîtier d'injecteur (55) et l'écrou de serrage (77).
(DE) Dual-Fuel-Kraftstoffinjektor (1) mit einer Gas-Injektorbaugruppe sowie einer Flüssigkraftstoff- Injektorbaugruppe, aufweisend: - ein Injektorgehäuse (55), - eine Spannmutter (77), welche an dem Injektorgehäuse (55) verspannend und dieses über einen Abschnitt umgebend angeordnet ist; dadurch gekennzeichnet, dass zwischen dem Injektorgehäuse (55) und der Spannmutter (77) ein Gasspeicherraum (85) gebildet ist.
