摘要：
An electromagnetic fuel injection valve in which an area of an annular gap formed by a ball valve and a valve seat when the ball valve is lifted is made smaller than cross sectional area of grooves provided on a fuel swirling element which gives fuel supplied a swirling force and further is made larger than a cross sectional area of a fuel injection port, whereby the fuel is injected with an excellent atomizing characteristic.
