Abstract
The invention has an object for improving response of a fuel injection device. A flow-in recessed portion and a flow-out recessed portion are formed at a press-contacting surface of a floating plate, which is movably accommodated in a pressure control chamber. A flow-in port and a flow-out port are formed at a pressure control surface of a valve body. The flow-in port is opened to the flow-in recessed portion, while the flow-out port is opened to the flow-out recessed portion. When the floating plate is moved upwardly and the press-contacting surface is brought into contact with the pressure control surface, the flow-in port is surely closed.
