Abstract (en)
[origin: DE19918976A1] The invention relates to a fuel injection valve (1), especially an injection valve for fuel injection systems of internal combustion engines. The inventive fuel injection valve has a first piezoelectric or magnetorestrictive actuator (14), a valve closing body (8), which can be activated by said first actuator by means of a valve needle (7) and which interacts with a valve seat surface (8) to form a tight seat, and a second piezoelectric or magnetorestrictive actuator (15), which acts on the valve needle in the opposite way to the first actuator (14). The actuators (14, 15) are interconnected by a bearing element (11) that is mounted in a fixed position in the fuel injection valve (1).
