FUEL INJECTION VALVE

FUEL INJECTION VALVE

Provided is a fuel injection valve capable of correcting an eccentricity of a valve body. For this reason, a fuel injection valve 100 includes a valve body 101; a mover 201 that drives the valve body 101; a fixed core 107 (magnetic core) that attracts the mover 201; and a flow path 107D-133F (magnet...

Zusammenfassung:Provided is a fuel injection valve capable of correcting an eccentricity of a valve body. For this reason, a fuel injection valve 100 includes a valve body 101; a mover 201 that drives the valve body 101; a fixed core 107 (magnetic core) that attracts the mover 201; and a flow path 107D-133F (magnetic core downstream flow path) representing a flow path that is formed on a downstream side of the fixed core 107. The mover 201 includes an upstream flow path 201C (mover upstream flow path) representing a flow path that is connected to the flow path 107D-133F to allow fuel to flow downstream. The radial lengths (L21 and L22) of an overlap between a downstream opening surface of the flow path 107D-133F and an upstream opening surface of the upstream flow path 201C are smaller than the radial lengths (L11 and L12) of the flow path 107D-133F.
