Document Type and Number:
WIPO Patent Application WO/2019/087326
Kind Code:
A1
Abstract:
Provided is a fuel injection valve for internal combustion engine with which atomization characteristics are maintained in a suitable state, even if impurities are deposited thereupon. The fuel injection valve has a valve 10 for opening and closing a valve seat 12, and by operating the valve 10, fuel is injected from a plurality of injection holes 14 provided to an injection hole plate 13 fitted to the downstream side opening of the valve seat 12. The injection hole plate 13 is equipped with a rotating chamber 18 which imparts a rotating force to the fuel and injects the fuel from the injection holes 14 to the exterior, and a fuel passage 17 which introduces fuel into the rotating chamber 18. The rotating chamber 18 has, at a position where the sidewall portion and the bottom portion thereof intersect, a recess 19 which is recessed into the sidewall portion of the rotating chamber 18 in the direction of expansion of the rotating chamber.
