Abstract

The invention relates to a fuel-injection valve (1), in particular a fuel-injection valve for the fuel-injection systems of internal combustion engines, comprising a valve housing (2) that contains a piezoelectric actuator (6). The actuator (6) is at least indirectly supported on the valve housing (2). The valve also comprises a valve closing body (17), which can be actuated by the actuator (6) by means of a valve needle (13) and co-operates with a valve seat surface (16) to form a seal seat. In addition, a decoupling element (8) is provided, said element being used to support the actuator (6) on the valve housing (2) or to help the actuator (6) to actuate the valve closing body (17) in conjunction with the valve needle (13). The decoupling element (8) absorbs part of the mechanical energy that is converted by the actuator (6) when the latter (6) is activated to actuate the valve closing body (17), in order to cushion the actuation of the valve closing body (17).
