Abstract
Provided is a fuel injection valve which achieves both atomization of a fluid spray and improvement of the degree of freedom in design of a spray shape, a spray direction, etc. According to a fuel injection valve () of the present invention, at least one of injection holes is a switching-spray injection hole (B), which corresponds to an injected spray, directions of a long axis and a short axis of a switching spray (A) changing due to an axis-switching phenomenon to deform the switching spray (A) at downstream. The plurality of injection holes other than the switching-spray injection hole (B) are coalescent-spray injection holes (A) for forming a coalescent spray () formed by coalescence under Coanda effect exerted between single sprays (A,A). The coalescent spray () and the switching spray (A) coalesce under the Coanda effect to form an integrated spray ().
