| 摘要 |
An electro-magnetic fuel injection valve for low pressure fuel injection systems of internal combustion engines utilizing induction tube injection which includes a housing, a stationary iron core located within the housing, with the core supporting a magnetic winding, an armature-plunger concentric with respect to the iron core, a valve needle, a hollow stem connected to the housing into which the valve needle extends and a valve seat defining structure for the valve needle situated within the hollow stem. The valve seat defining structure having a plurality of bores formed therein the dimensions of which determine the apportionment of fuel by the fuel injection valve, and the disposition of which permits utilization of the kinetic energy, which results from the transformation of the pressure energy during the fuel apportionment, in the preparation of the fuel.
