Abstract
An electromagnetic fuel injection valve for use in an internal combustion engine includes a valve body provided with a valve seat and a valve member having an abutting part moved within the valve body by an electromagnetic actuator between a closed position where the abutting part abuts against the valve seat to interrupt supply of fuel to the engine and an open position where the abutting portion is spaced from the valve seat to permit supply of the fuel to the engine. The valve member has a metering portion which cooperates with the valve seat to define therebetween a fuel metering gap when the valve member is in the open position. The abutting part of the valve member is located downstream of the metering portion with reference to a flow direction of the fuel so that the metering portion is always immersed in the fuel when the valve member is in the closed position.
