Abstract
A fuel passage is formed through a movable core and a fixed core of a fuel injection valve. Communication passage(s) are formed in the movable core or the fixed core around the fuel passage. The communication passage(s) connect a facing space provided between the movable core and the fixed core with a space remote from the facing space. Fuel flows out of the facing space through the communication passage(s) when the fuel injection valve is opened and fuel flows into the facing space through the communication passage(s) when the fuel injection valve is closed.
