Abstract

Die vorliegende Erfindung betrifft einen Kraftstoffspeicher zur Speicherung von Kraftstoff für eine Einspritzvorrichtung, wobei der Kraftstoffspeicher (1) mehrere Bohrungen (2) aufweist, an denen jeweils eine erste Dichtfläche (3) zur Abdichtung des Kraftstoffspeichers nach außen ausgebildet ist. Weiterhin ist an wenigstens einer Bohrung (2) eine zweite Dichtfläche (4) ausgebildet, welche zur Abdichtung des Kraftstoffspeichers bei einer Dichtheitsprüfung verwendet wird. Weiterhin betrifft die vorliegende Erfindung ein Verfahren zur Dichtheitsprüfung eines Kraftstoffspeichers.

The invention relates to a fuel accumulator for storing fuel for an injection device, the fuel accumulator (1) having a plurality of bores (2), on each of which a first sealing surface (3) for sealing the fuel accumulator to the outside is formed. Furthermore, a second sealing surface (4) is formed on at least one bore (2), which is used to seal the fuel accumulator during a leak test. Furthermore, the present invention relates to a method for leak testing a fuel accumulator.
