Fuel injector valve

The injection valve (1) has a control chamber (27) connected with a valve chamber (31) of a control valve (30) by a discharge borehole (34), where the control valve has a spring element (45) arranged in the valve chamber. The control valve has a valve bolt (38) comprising a valve body (39) cooperating with a valve seat surface (40) at a seal seat (41). The seal seat controls flow of fuel from the valve chamber, and the valve bolt is guided into a guide borehole (51) of an intermediate plate (8), where a side (12) of the intermediate plate limits the valve chamber.
