Abstract

Kraftstoffhochdrucksystem für die Versorgung einer Brennkraftmaschine mit einem Gehäuse (1), das wenigstens zwei Hochdruckkörper (3; 5; 6) umfasst, welche mit je einer Anlagefläche (103; 105; 106; 206) aneinander anliegen. In den Hochdruckkörpern (3; 5; 6) ist ein Hochdruckkanal (8) ausgebildet, in dem zumindest zeitweise Kraftstoff unter hohem Druck vorhanden ist und der durch die Anlageflächen (103; 105; 106; 206) der wenigstens zwei Hochdruckkörper (3; 5; 6) hindurchtritt. Im Gehäuse (1) ist ein Leckölraum (21) vorhanden, in dem stets ein niedriger Kraftstoffdruck herrscht. Auf wenigstens einer Anlagefläche (103; 105; 106; 206) ist ein Leckagekanal (35) ausgebildet, der den Durchtritt des Hochdruckkanals (8) durch diese Anlagefläche (103; 105; 106; 206) umgibt und der mit dem Leckölraum (21) verbunden ist (Figur 1).
