摘要： A fuel inlet (36) opens at one end between the valve seat (14) and the inner surface of the valve housing (12) on which the globe valve (10) slides. The other end of the fuel inlet (36) opens to the external surface of the valve housing (12). The fuel inlet (36) runs almost in the direction of the central axis of the globe valve (10) so as to prevent the formation of vortex flow around the globe valve (10). Inside the valve housing (12) immedi. ately downstream of the valve seat (14) is fitted under pressure a spiral member (40) which is a rod with a spiral fuel groove (38) to swirl the fuel along the groove. Ano αtlet orifice (42) for fuel metering is formed immediately downstream of and as close as possible to the spiral member (40). In an other embodiment of the invention the valve housting (12) is surrounded by a housing (43) with fuel inlets (36'). This housing (43) is fightly connected to the downstream-end of the valve housing (12) having tangential bores (44) for assisting air-inlet joining with a conical space (45) and blowing the assisting air towards the axis of the outlet orifice (42).

摘要： An electromagnetic fuel injection valve in which an area of an annular gap formed by a ball valve (6) and a valve seat (9) when the ball valve (6) is lifted is made smaller than cross sectional area of grooves (50) provided on a fuel swirling element (37) which gives fuel supplied a swirling force and further is made larger than a cross sectional area of a fuel injection port (8), whereby the fuel is injected with an excellent atomizing characteristic.
