The fuel injector comprises a magnetic valve member with three dimensions of the same magnitude, a valve member seat on which the valve member is seatable, a magnetic core disposed opposite to the valve member seat and excitable by a solenoid to attract the valve member and generate a clearance between the seat and the valve member which allows the flow of fuel, and an injection section through which the fuel which has passed the clearance is injected out of the injector. The valve seat is shaped as a duct and the clearance between the valve member and the seat has a first portion of decreasing section and a second portion of increasing section.
