Abstract
A movable plate is movably accommodated in a pressure control chamber. A fixed plate is arranged above the movable plate, so that the movable plate is brought into contact with the fixed plate. The fixed plate has a high pressure passage for supplying fuel into the pressure control chamber and a low pressure passage for discharging the fuel from the pressure control chamber. A high pressure port and a low pressure port are formed at a lower end surface of the fixed plate. A first contacting surface is formed at the lower end surface and a first groove is formed in the first contacting surface for holding a part of fuel in a plate-contacted condition.
