Abstract
A cylinder injection type fuel injection valve has a metallic ring 15 of a substantially T-like shape which is disposed inside a solenoid 2 and which has inner and outer sides supported by O-rings 16, 17 in order to seal highly pressurized fuel, whereby a change in a flow rate of fuel, which may be resulted by attaching the fuel injection valve to an internal combustion engine, can be minimized without changing largely a sealing structure for fuel, and deformation of the metallic ring is minimized.
