Title
(DE) BRENNSTOFFEINSPRITZVORRICHTUNG
(EN) FUEL INJECTION DEVICE
(FR) DISPOSITIF D'INJECTION DE CARBURANT
Abstract
(DE)
Eine Brennstoffeinspritzvorrichtung für eine Brennkraftmaschine weist einen Brennstoffverteiler (10), der eine Mehrzahl von Anschlussstutzen (11) zur flüssigkeitsdichten Aufnahme von Brennstoffeinspritzventilen (12) trägt, auf. An jedem Anschlussstutzen (11) sind erste Verbindungsmittel (22) und an jedem Brennstoffeinspritzventil (12) sind zweite Verbindungsmittel (23) zur Erzielung einer sicheren Verbindung vorgesehen. Die ersten Verbindungsmittel (22) am Anschlussstutzen (11) ragen radial nach innen. Das zweite Verbindungsmittel (23) am Brennstoffeinspritzventil (12) ist als nutförmige Vertiefung ausgebildet. Der Anschlussstutzen (11) besitzt in seinem die ersten Verbindungsmittel (22) aufweisenden Endabschnitt (25) wenigstens eine schlitzartige Unterbrechung (26).
(EN)
The invention relates to a fuel injection device for an internal combustion engine. Said device is provided with a fuel dispenser (10) which supports a plurality of connecting parts (11) that accommodate liquid-tight fuel injection valves (12). First connecting means (22) are arranged on each connecting part (11) and second connecting means (23) are arranged on each fuel injection valve (12) in order to guarantee a secure connection. The first connecting means (22) at the connecting part (11) extend radially inwards. The second connecting means (23) on the fuel injection valve (12) is embodied as groove-shaped cavity. The connecting part (11) is provided with a slit-like gap (26) in the end section (25) thereof that is provided with the first connecting means (22).
(FR)
Un dispositif d'injection de carburant pour moteur à combustion interne présente un distributeur de carburant (10) portant une pluralité de tubulures de raccordement (11) pour le logement de soupapes d'injection de carburant (12) étanches au liquide. Il est prévu, sur chaque tubulure (11), des premiers moyens de connexion (22), et sur chaque soupape d'injection (12), des seconds moyens de connexion (23) en vue d'obtenir une connexion fiable. Les premiers moyens de connexion (22) sur les tubulures (11) s'étendent radialement vers l'intérieur. Les seconds moyens de connexion (23) sur les soupapes d'injection (12) sont constitués par des évidements en forme de rainures. La tubulure (11) comporte, dans sa section d'extrémité (25) présentant les premiers moyens de connexion (22), une discontinuité en forme de fente (26).
