Abstract (en)
[origin: WO2005052354A1] The invention relates to a fuel injection device (10) comprising at least two coaxial valve elements (20, 22) arranged in a housing (12). At least one fuel outlet (24, 26) is respectively associated with said valve elements. The outer valve element (20) is provided with a first sealing edge (64) oriented radially outwards in relation to the at least one fuel outlet (24) associated with the outer valve element. Said sealing edge co-operates with a valve seat (66) on the housing side and can separate the at least one fuel outlet (24) from a high pressure connection. According to the invention, the outer valve element (20) is provided with an additional sealing edge (72) between the at least one fuel outlet (24) associated with the outer valve element and the inner valve element (22).
