Abstract

Die Erfindung bezieht sich auf einen Kraftstoffhochdruckspeicher eines eine Brennkraftmaschine mit Kraftstoff versorgenden Common Rail-Kraftstoffeinspritzsystems. Der Kraftstoffhochdruckspeicher umfasst einen rohrförmigen Grundkörper (1), dessen Begrenzungswand (19) einen in Längsrichtung verlaufenden Hohlraum (2) umschließt. Am rohrförmigen Grundkörper (1) sind mehrere Anschlüsse (8, 9, 10) zum Anschluss von Kraftstoffhochdruckleitungen vorgesehen. Die Anschlüsse (8, 9, 10) für Kraftstoffhochdruckleitungen sind vom rohrförmigen Grundkörper (1) entkoppelt angeordnet.

The invention relates to a high-pressure fuel accumulator of a common rail fuel injection system that supplies an internal combustion engine with fuel. The high-pressure fuel accumulator comprises a tubular base body (1), the boundary wall (19) of which surrounds a cavity (2) extending in the longitudinal direction. A plurality of connections (8, 9, 10) are provided on the tubular base body (1) for connecting high-pressure fuel lines. The connections (8, 9, 10) for high-pressure fuel lines are decoupled from the tubular base body (1).
