Fuel injector valve

The fuel injection valve (1) comprises a control valve (25) and a control chamber (17). The control chamber is connected with a valve chamber (24) of the control valve by a discharge channel (22). The control valve comprises a valve pin (26) with a valve body (27) arranged in the valve chamber. The valve body interacts on one side with a valve seat surface to a sealing seat, by which a connection of the valve chamber with a pressure-release chamber (41) is controlled.
