摘要： A valve body surrounds a first passage connecting with a cylinder of an engine. A valve member is adapted to be seated on and lifted from the valve seat. An injector body connects with the valve body. The injector body has a pressure control chamber for controlling hydraulic pressure applied to the valve member thereby controlling a lift of the valve member. The injector body has a second passage through which fuel in the pressure control chamber is exhausted. An actuator is adapted to communicating the pressure control chamber with the first passage through the second passage and blocking the pressure control chamber from the first passage. The first passage introduces fuel from the pressure control chamber into the cylinder through the second passage.

摘要： A fuel injection valve includes a valve body having a valve seat, a valve element adapted to sit on and leave a valve seat, a nozzle hole for the injection of fuel, and an electromagnetic drive section. A holding member surrounds and holds, on one end side thereof, at least a partial area of an opposite-to-nozzle-hole-side end face portion of the valve element. The holding member surrounds and holds, on an opposite end side thereof, a predetermined surface area of a constant position holding portion without being influenced by the pressure of fuel flowing through a fuel passage of the valve body and irrespective of movement of the valve element. An internal area of the holding member is shut off so as not to be influenced by the pressure of fuel present around the internal area.

摘要： A fuel injection valve includes a needle valve having an engagement part, and a movable core having an engagement part to be engaged with the engagement part of the needle valve. One of the engagement part of the needle valve and the engagement part of the movable core is defined by two inner faces of a recess opposing to each other in an axis direction, and the other engagement part is defined by two outer faces of a projection opposing to the inner faces, respectively. The projection is movable between the inner faces in the axis direction in a state that the projection is located in the recess.
