Title:
燃料噴射弁
Document Type and Number:
Japanese Patent JP5610079
Kind Code:
B2
Abstract:
A fuel injection valve that can favorably reduce the film thickness of fuel ejected from an outlet of an injection hole without relying on increase of the fuel pressure, whereby atomization of fuel spray can be favorably promoted, is provided. A fuel passage (16) through which the fuel flows is formed in the interior of the fuel injection valve (10). An injection-hole plate (18) as a member that separates an injection space (20) into which the fuel is injected, from the fuel passage (16), is provided in which a plurality of injection holes (22) for ejecting the fuel from the fuel passage (16) toward the injection space (20) are formed. The injection-hole plate (18), as viewed from the outlet side of the injection hole (22), is formed with an injection-hole outlet-side groove (24) connected to the injection hole (22) in a region (inner wall surface 22b) opposed to a main flow direction of the fuel directed toward the injection hole (22) along an inner wall surface (18a) of the injection-hole plate (18). The injection-hole outlet-side groove (24) is formed so as to extend in a direction away from the injection hole (22).
