摘要：燃料噴射弁(1)の弁装置において、シート面(13)を下流側へ延長した仮想円錐(13b)の頂点と弁座(11)の中心軸Zとの交点(13c)が、開口部(15)内に位置するようにした。これにより、シート部(13a)を通過した燃料の多くが開口部(15)で合流した後、噴孔プレート(22)上面に到達しスムーズに外周側に向かう流れに転じることから、この間の燃料の圧力損失が小さく抑えられる。このため、前記燃料噴射弁(1)の弁装置において、噴孔直上部(22b)における燃料速度の低下が抑制され、燃料噴霧の微粒化が促進される。

摘要： PROBLEM TO BE SOLVED: To improve fuel consumption by promoting spray atomization by forming a liquid film within an injection hole of a fuel injection valve. SOLUTION: A fuel injection valve includes: a valve seat including a conical valve seating surface; a valve element which opens/closes a fuel passage by separating/contacting a spherical surface from/to the valve seating surface and control the supply of a fuel to an engine suction pipe; and an injection hole plate which includes a plurality of injection holes each for injecting the fuel to the engine suction pipe and is disposed while being confronted with a downstream surface of the valve element. The injection holes are disposed in such a manner that the fuel flowing down along with the valve seating surface from between a point (seat part D) on the valve seating surface which is abutted with the spherical surface while the valve is closed, and the spherical surface does not directly flow into an injection inlet S3 farthest from the seat part D while directly flowing into an injection hole inlet S2 closest to the seat part D. Therefore, a liquid film of the fuel is formed within the injection hole while providing a flowing velocity difference to the fuels entering the injection holes. COPYRIGHT: (C)2013,JPO&INPIT

摘要： A method of generating a spray by a fluid injection valve is provided. The fluid injection valve includes a valve seat (10), a valve body (8), and an orifice plate (11) having a plurality of orifices (12). The flows in the orifices and the flows directly below the orifices are configured to be substantially liquid film flows. The directions of jet flows (30), (31) from the respective orifices (12) are not necessarily matched to the central axis directions of the orifices and are not necessarily intersected with each other at a downstream position thereof. The sprays are caused to converge by the Coanda effect acting on a plurality of sprays after jet flows from the orifices (12) become sprays at a downstream position farther than a break-up length (a). The convergence of the sprays is continued until the Coanda effect is substantially lost.
