Abstract:
A fuel injection valve has a valve body, a valve seat member having a valve seat and an opening portion formed at a downstream side of the valve seat member, a swirl chamber providing swirl to fuel, an orifice nozzle formed at a bottom of the swirl chamber and jetting the fuel, a communication conduit connecting the swirl chamber and the opening portion of the valve seat member, and a fuel inflow prevention wall provided at a connecting area between the communication conduit and the swirl chamber. The fuel inflow prevention wall is formed so as to prevent an incoming fuel from the communication conduit from directly flowing into the orifice nozzle and to suppresse a collision between a flow of the fuel that swirls and comes to the connecting area and a fuel flow coming from the communication conduit.
