Abstract (en)

[origin: WO2004094811A1] Disclosed is a fuel injection valve (1), especially for fuel injection systems of internal combustion engines, comprising a piezoelectric or magnetorestrictive actuator (4) which can be excited via an electric wire (6) and actuates a valve-sealing body (15) that is disposed inside a housing (2) and cooperates with a valve seat area (16) so as to form a sealing seat. The inventive fuel injection valve (1) further comprises a hydraulic coupling member (10) that is provided with a recess (13) at the discharge end, into which one end (12) of a valve needle (11) engages in a pivotable manner.
