Abstract
A fuel injecting apparatus includes a housing, a bobbin around which a coil is wound, a first core member disposed at one side of the bobbin, a second core member disposed in the bobbin so as to define a clearance with the first core member, and a nozzle disposed at one end of the housing which has an injecting opening. A first movable member is disposed in the bobbin and includes a first projection portion which forms a first gap with the second core member, and a second movable member is disposed in the bobbin and includes a second projection portion which forms a second gap with the first core member. The second movable member includes a fuel measuring device therein. A third movable member is slidably fit in the nozzle so as to define a third gap at one end thereof with the second movable member, and a valve member is disposed between the first movable member and the second movable member. A first spring member is disposed between the first core member and the second projection portion of the second movable member, while a second spring member is disposed between the first core member and the first projection portion of the first movable member. The second spring member includes a spring force which is larger than that of the first spring member. A third spring member is also provided which forces the third movable member so as to close the injecting opening.
