Title
(DE) KRAFTSTOFFVERTEILER FÜR KRAFTSTOFFEINSPRITZANLAGEN VON BRENNKRAFTMASCHINEN
(EN) FUEL DISTRIBUTOR FOR FUEL INJECTION INSTALLATIONS IN INTERNAL COMBUSTION ENGINES
(FR) DISTRIBUTEUR DE CARBURANT POUR LES SYSTEMES D'INJECTION DES MOTEURS A COMBUSTION INTERNE
Abstract
(DE)
Ein Kraftstoffverteiler für Kraftstoffeinspritzanlagen von Brennkraftmaschinen weist ein Verteilergehäuse (10) mit einer Mehrzahl von durch eine Kraftstoffversorgungsleitung miteinander verbundenen Aufnahmebohrungen (11) zur Aufnahme von elektromagnetisch betätigten Kraftstoffeinspritzventilen (17), einen auf dem Verteilergehäuse (10) festgespannten Niederhalter (22) zum Arretieren der Kraftstoffeinspritzventile (17) in den Aufnahmebohrungen (11) und Befestigungsmittel zur Befestigung am Saugrohr (13) der Brennkraftmaschine auf. Zur Geräuschabkopplung des Kraftstoffverteilers von den benachbarten Anbauteilen ist einerseits zwischen dem Verteilergehäuse (10) und dem Niederhalter (22) eine geräuschabkoppelnde Flachdichtung (25) eingelegt und andererseits sind die Befestigungsmittel von Schwingmetallelementen (32) gebildet. Bei Kunststoffausführung des Kraftstoffverteilers sind die Schwingmetallelemente (32) bevorzugt aus einer Spannschraube (43), einer metallischen Distanzhülse (45) und einer elastischen Hülse (36), die in der genannten Reihenfolge koaxial angeordnet sind und Durchgangsbohrungen (38, 39) im Verteilergehäuse (10) und Niederhalter (22) durchdringen, ausgeführt.
(EN)
A fuel distributor for fuel injection installations in internal combustion engines has a distributor casing (10) with a plurality of drillings (11) interconnected by a fuel supply pipe to take electromagnetically actuated fuel injection valves (17), a clamp (22) stretched on the distributor casing (10) to hold the fuel injection valves (17) in the drillings (11) and means of securing on the inlet pipe (13) of the engine. To prevent the transmission of noise between the fuel distributor and the neighbouring components, a flat sound-insulating seal (25) is inserted between the distributor casing (10) and the clamp (22) and the securing means are made of oscillating metal components (32). Where the fuel distributor is made of plastic, the oscillating metal components (32) preferably consist of a turnbuckle (43), a metal spacer (45) and an elastic sleeve (36) which are arranged coaxially in the above order and pass through drillings (38, 39) in the distributor casing (10) and the clamp (22).
(FR)
Distributeur de carburant pour les systèmes d'injection des moteurs à combustion interne comprenant un carter de distributeur (10) comportant plusieurs orifices (11) reliés entre eux par une conduite d'alimentation en carburant et destinés à recevoir des soupapes d'injection de carburant (17), à commande électromagnétique, un serre-tôle (22) fixé sur le carter (10) du distributeur et servant à bloquer les soupapes d'injection de carburant (17) dans les orifices (11) et des dispositifs de fixation sur la conduite d'aspiration (13) du moteur. Pour assurer l'isolation acoustique du distributeur de carburant par rapport aux pièces voisines, d'unepar on insère un joint plat (25) insonorisant entre le carter (10) du distributeur et le serre-tôle (22) et, d'autre part, on emploie des dispositifs de fixation formés d'éléments caoutchouc-métal (32). Lorsque le distributeur est réalisé en matière plastique, les éléments caoutchouc-métal (32) sont constitués, de préférence, d'une vis de serrage (43), d'une douille métallique d'écartement (45) et d'une douille élastique (36), ces pièces étant disposées dans le même axe et dans cet ordre et traversant des orifices de passage (38, 39) pratiqués dans le carter (10) du distributeur et le serre-tôle (22).
