摘要： A fuel injector comprises, a fuel flow adjustment throttle for determining a flow rate of a fuel passing through the fuel injector, a first member having a cylindrical surface for defining partially the fuel flow adjustment throttle, and a second member including a first surface and a second surface both of which extend toward the first member and join each other at a pointed edge defining the fuel flow adjustment throttle together with the cylindrical surface of the first member, and at least one of which forms a space expanding gradually in a fuel flow direction.
