Abstract
A fuel injection port formed in a seat is opened and closed by a movable valve supported by a flat spring . The movable valve is biased by an elastic force of a coil spring in a direction that closes the fuel injection port . When electric power is supplied to a solenoid coil , the movable valve is moved to a direction that opens the fuel injection port as a result of an electromagnetic attraction force between a magnetic circuit M for generating an electromagnetic attraction force and the movable valve . Air gaps G , G and G are formed within the fuel injection port and permeance ratios between the air gaps may be set to optimal valves.
