摘要 |
A fuel injection valve includes a valve seat (11) that has a valve seat portion (11a) with a conical space defined therein and tapered toward an injection hole (11b), a needle (12) that has a valve portion (12b) formed with a curved surface for abutment with the valve seat portion (11a) and a column-shaped sliding portion (12a) located upstream of the valve seat portion (11a), and a swirler (10) that holds the sliding portion (12a) in a slidable manner, wherein fuel to be injected from the injection hole (11b) is adjusted by opening and closing a gap between the valve portion (12b) and said valve seat (11a), and assuming that a radius of curvature in an axial direction of the valve portion (12b) at a point at which the valve portion (12b) and the valve seat portion (11a) are in abutment with each other is R and an outer diameter of the sliding portion (12a) is D, R is greater than D/2. |
