Abstract

Kraftstoffeinspritzventil für eine Hochdruckeinspritzung von Kraftstoff aus einer zentralen Hochdruckleitung in Brennräume einer Verbrennungskraftmaschine, das ein Schaltventil mit einem Ventilsitz (51) und einer Ventilkugel (50) umfasst, wobei die Ventilkugel (50) in geöffnetem Zustand mittels eines Hochdruckstrahls, der von einem mit einer zentralen Hochdruckleitung in Wirkverbindung stehenden Druckraum (20) aus einer Drosselbohrung (15) gespeist ist, vom Ventilsitz (51) abgehoben ist. Der Übergang von der Drosselbohrung (15) zum Ventilsitz (51) ist als Diffusor ausgebildet.
