Abstract

PURPOSE:To prevent the chage of fuel pressure in a fuel chamber of a three-way valve type fuel injection solenoid valve by constructing another valve of a valve body to set on or off an injection port and a valve body guide part for obtaining the continuous flow of the fuel introduced into the fuel chamber. CONSTITUTION:A spring adjustment screw 28, a plunger 23, and a valve rod 25 on the center line of a center pole 21 in a fuel injection solenoid valve to set on or off an injection port 30 by the operation of a solenoid coil 22 are provided with vertical holes connected with each other for constructing a fuel return passage 35. A valve body 24 is shaped into a cap in one body with the valve rod 25, and in a lift set part 36 where the face of its large diameter end is brought in contact with a valve guide 26, the end of the above-said vertical hole 35 is radially shaped into an opening 38 for constructing another valve part 37 there. This valve part 37 is off by being closely stuck to the lift set part 36 of the valve guide 26 when the injection port 30 is on, and on by the projecting of the valve body 24 to open the radial opening 38 when the injection port 30 is off.
