Patent ID: 8684285

Claim:
A fuel injection valve comprising: a housing that is configured into a tubular form; a nozzle that is located at one end portion of the housing and includes a fuel injection hole and a valve seat; a stationary core that is held in an inside of the housing and is configured into a tubular form; a needle that is received in the housing and is adapted to reciprocate in an axial direction, wherein the needle includes: a main body that is configured into an elongated rod form and has a sealing portion, which is formed at one end portion of the main body and is seatable against the valve seat; and a flange that radially outwardly extends from the other end portion of the main body, which is opposite from the one end portion of the main body, wherein the needle opens the fuel injection hole when the sealing portion is lifted away from the valve seat in an opening direction, and the needle closes the fuel injection hole when the sealing portion is seated against the valve seat in a closing direction, which is axially opposite from the opening direction; a movable core that is axially placed between the stationary core and the nozzle in the inside of the housing and is adapted to reciprocate in the axial direction, wherein the movable core includes: a through-hole that axially extends through the movable core and receives the main body of the needle therethrough; and a receiving recess that is axially recessed in a stationary core side end surface of the movable core located on an axial side where the stationary core is placed, wherein the receiving recess is configured into an annular form and radially outwardly extends from the through-hole to receive the flange of the needle; a movable plate that is placed on an axial side of the movable core, which is opposite from the nozzle, wherein an outer diameter of the movable plate is larger than an inner diameter of the receiving recess, and the movable plate is contactable with the movable core and the needle; a first urging member that urges the movable plate to urge the movable core in the closing direction; a second urging member that has an urging force, which is smaller than an urging force of the first urging member, wherein the second urging member urges the movable core to urge the movable plate in the opening direction; and a coil that generates a magnetic force upon receiving an electric power to magnetically attract the movable core toward the stationary core side, wherein: an axial length of the flange is smaller than an axial distance between a contact surface of the movable plate, which is contactable with the needle, and a bottom wall of the receiving recess in a contact state where the movable core and the movable plate contact with each other in the axial direction.
