Abstract (en)
[origin: DE19912665A1] The invention relates to a fuel injection valve (1), more particularly, an injection valve in fuel injection systems of internal combustion engines, having a fuel inlet (4) for supplying fuel, a piezoelectric or magnetorestrictive actuator (13) which is sealed against the fuel by a sealing (18, 19) and a valve closing body (6) which can be actuated by the actuator (13) by means of a valve needle (5). The valve closing body (6) engages with a valve seat surface (8) to form a sealed seat. The sealing (18, 19) comprises a sealing plate (18) that is arranged between the fuel inlet (4) and the actuator (13) and that is provided with a fuel channel (21') in order to supply the fuel from the fuel inlet (4) in the direction towards the sealed seat.
