Abstract
A valve back pressure chamber is provided to exert a back pressure of a first valve needle. Furthermore, a hydraulic pressure passage is provided to extend through the valve back pressure chamber. A valve body is provided to a second valve needle and is driven to connect and disconnect between the hydraulic pressure passage and a fuel tank and thereby to drive the first valve needle. The second valve needle is driven by hydraulic pressure induced by an actuator.
