Abstract
An electromagnetic fuel injector for internal combustion engines comprises a yoke containing a coil and cores; a cylinder secured to the yoke and therein forming a nozzle, a valve seat, a valve guide bore, and a plurality of fine fuel passages formed between the valve seat and the termination of the valve guide bore; a ball valve connected to a plunger with flange and inserted slidably in said valve guide bore; a holder of a dense material mounted at one end on the cylinder with a little gap therebetween and with a O-ring being pressed in the radial direction, and secured fluid-tightly at the other end to the yoke thereby to define an annular fuel reservoir around the cylinder. A pair of fuel pipes are connected to the holder. Further, a cap is mounted in the front of the holder to jet fuel from the nozzle whereby fuel is atomized.
