Claims

[Scope of utility model registration request]

(1) In an electromagnetic fuel injection valve in which the pole valve is repeatedly opened and closed by the interaction between electromagnetic attraction force and a spring force acting in the valve closing direction, there is a valve located downstream of the valve seat and concentric with the valve seat. A swivel plate having a swiveling introduction groove consisting of a plurality of through holes arranged on the same circumference and a notch press-formed so as to diagonally expand in the circumferential direction toward the upstream side from the through hole; ,
a pressure plate having a circular hole in the center serving as a pressure chamber sized to encompass each rotation introduction groove of the rotation plate, and each rotation of the rotation plate for metering the fuel flow rate and atomizing the fuel for atomization; Orifice plates each having an orifice with a cross-sectional area smaller than the sum of the cross-sectional areas of the introduction grooves are arranged one on top of the other in order, and the circulation plate, pressure plate, and orifice plate described in 5 above are each configured as thin plates. An electromagnetic fuel injection valve characterized by:

(2) Swivel plate, pressure plate and orifice plate are each 0°47
71,771 or less, the electromagnetic fuel injection valve according to claim 1 of the utility model registration.

(3) Utility model registration claim 1 or 2, characterized in that the through hole of the rotation introduction groove of the rotation plate is press-molded integrally with the notch at the same time as the press-molding of the notch. The electromagnetic fuel injection valve described.
