Patent ID: 7216632

Claim:
A fuel injection valve that injects fuel into a cylinder of an internal combustion engine, the fuel injection valve comprising: a valve body that faces an interior of the cylinder, the valve body surrounding a first passage connecting with the cylinder, the valve body having a valve seat; a valve member that is adapted to be seated on the valve seat, the valve member being adapted to be lifted from the valve seat; an injector body that connects with the valve body, the injector body having a pressure control chamber for controlling hydraulic pressure applied to the valve member from an opposite side of the valve seat thereby controlling a lift of the valve member, the injector body having a second passage through which fuel in the pressure control chamber is exhausted; and an actuator that is adapted to communicate the pressure control chamber with the first passage through the second passage, the actuator being adapted to block the pressure control chamber from the first passage, wherein the first passage introduces fuel from the pressure control chamber into the cylinder through the second passage.
