Title
(DE) KRAFTSTOFFHOCHDRUCKSPEICHER
(EN) HIGH PRESSURE RESERVOIR FOR FUEL
(FR) ACCUMULATEUR DE CARBURANT HAUTE PRESSION
Abstract
(DE) Die Erfindung betrifft einen Kraftstoffhochdruckspeicher für ein Common-Rail-Kraftstoffeinspritzsystem einer Brennkraftmaschine, mit einem rohrförmigen Grundkörper (1), der mit mehreren Anschlüssen (5 bis 8) ausgestattet ist. Um einen Kraftstoffhochdruckspeicher zu schaffen, der für eine grosse Anzahl ähnlicher Motoren verwendet werden kann, sind an dem rohrförmigen Grundkörper (1) eine durchgehende Anschlussleiste oder mehrere Anschlussstutzen (5 bis 8) ausgebildet, deren Abmessungen (b) in Längsrichtung des rohrförmigen Grundkörpers (1) grösser sind als der für die Anschlüsse (9) erforderliche Platz.
(EN) The invention relates to a high pressure reservoir for fuel for a common-rail fuel injection system of an internal combustion engine. Said reservoir comprises a tube-shaped base body (1) that is provided with several connections (5 to 8). The aim of the invention is to provide a high pressure reservoir for fuel, whereby said reservoir can be used for a high number of similar engines. To this end, a continuous connecting block or several connecting branches (5 to 8) are embodied at the tube-shaped base body (1). The dimensions (b) of said block or branches are greater than the space required for the connections (9) when seen in the longitudinal direction of the tube-shaped base body (1).
(FR) L'invention concerne un accumulateur de carburant haute pression pour un système d'injection de carburant à rampe commune d'un moteur à combustion interne, qui comprend un corps de base (1) tubulaire pourvu de plusieurs raccords (5 à 8). Pour que l'on obtienne un accumulateur de carburant haute pression pouvant être utilisé pour un grand nombre de moteurs semblables, sur le corps de base (1) tubulaire sont formés une barrette de raccordement ou plusieurs manchons de raccordement (5 à 8) dont les dimensions (B), dans le sens longitudinal du corps de base (1) tubulaire, sont plus grandes que celles de la place nécessaire pour les raccords (9).
