Summary:PROBLEM TO BE SOLVED: To realize a fuel injection valve capable of reducing the bouncing of a valve element without affected by reduction of viscosity of the fuel without strictly controlling the accuracy in dimensions of the valve element, the housing, a guide clearance and the like. SOLUTION: This fuel injection valve comprises a fuel injection hole 2, a valve seat 3 mounted near the fuel injection hole, the valve element 4 for opening and closing a fuel passage to the valve seat, a spring 12 generating the force pressing the valve element to the valve seat, and a driving means for driving the valve element. A spring part 17 is mounted on an upper part of the valve element 4, besides a cooperative member 13 is mounted between the valve element 4 and the spring 12 independently from the valve element. Whereby the impact energy between the valve element 4 and the valve seat 3 is absorbed, and the bouncing of the valve element 4 can be reduced. COPYRIGHT: (C)2005,JPO&NCIPI
