Fuel injection valve for a combustion engine
DRIVE
January 21, 2004
Fuel injection valve comprises a valve body (1) containing a bore (3) having a longitudinal axis (4) and defined at its combustion chamber end by a valve seat (5) having the inlet opening (107) of at least one injection channel (7) which opens into the combustion chamber of the engine, and a valve needle (10) movably arranged in the bore. The valve needle interacts with the valve seat via its valve-sealing surface (12) so that when the valve needle is lifted from the valve seat an annular gap is produced through which the fuel flows to the injection channel. In the case of at least one injection channel the distance between the inlet opening and the valve-sealing surface at at least two different points of the inlet opening is different.
