ELECTROMAGNETIC FUEL INJECTION VALVE

An electromagnetic fuel injection valve () is provided which suppresses overshoot and overshoot return, and reduces fluid pressure acting on a valve body () as much as possible. In the electromagnetic fuel injection valve (), lift of the valve body () to valve opening position performed against urging force of a return spring () in accordance with excitation of a coil is achieved by settling overshoot and overshoot return caused at that time. A small pitch part () of the return spring () exhibits a totally compressed state when lift amount of the valve body () is equal to or greater than a first lift amount smaller than valve opening lift amount corresponding to the valve opening position. A large pitch part (18) acts when the lift amount is equal to or greater than a second lift amount which is ½ or less of the valve opening lift amount.
