摘要： Multiple injection holes are formed in an injection hole plate. Each injection hole penetrates the injection hole plate. The injection hole is formed with an inlet side opening and an outlet side opening. The outlet side opening is formed in the shape of a flattened rectangle having a major axis and a minor axis. Therefore, the fuel flowing into the injection hole through the inlet side opening is injected in the shape of a film from the outlet side opening. Thus, liquid film splitting is promoted, so atomization of the fuel is promoted. Since the multiple injection holes are formed in the injection hole plate, the shape of a great fuel spray, which is formed by combining fuel sprays injected from the respective injection holes, can be adjusted easily.

摘要： In an injection hole plate of a fuel injection apparatus, a second-side hole section of each injection hole extends from a downstream end of a base wall of the injection hole plate and is communicated with first-side hole sections, which extends from an upstream end of the wall of the injection hole plate to an axially intermediate point of the wall. The first-side hole sections may discharge fuel into the second-side hole section in a manner that forms a swirl fuel flow in the second-side hole section. The injection hole plate may includes a collision portion, in which fuel flows supplied from the first-side hole sections collide with one another.

摘要： An injector has a lift limiting member provided by a single plate member. The plate member has a stopper face, multiple hole sections, a flow passage hole, and a spring seat face. An axial end face of a needle head section of a needle contacts the stopper face when the needle lifts by a predetermined amount. Transmitting sections of a pressurizing piston are loosely inserted in the hole sections. High pressure fuel can pass through the flow passage hole. The spring seat face receives an end portion of a spring that biases the needle in a valve closing direction. The lift limiting member limits a valve opening lift position of the needle, so a stable injection quantity is obtained. Thus, a surface area of the single plate member can be used in multiple functions.

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 needle is received in a nozzle body and is adapted to reciprocate relative to an injection hole to open and close the injection hole. A pressure chamber receives the fuel and exerts a pressure against the needle in an opening direction away from the injection hole upon increasing of the pressure of the fuel in the pressure chamber. A damper arrangement is actuated upon increasing of the pressure in the pressure chamber to alleviate a change in the pressure in the pressure chamber. A pressurizing piston reciprocates to increase and decrease the pressure of the fuel in the pressure chamber.

摘要： A piston can reciprocate in a piston guide cylinder in an axial direction and has a cavity on a piezo driver side thereof. If the piezo driver is energized, a tip of a projecting section of a pushing member pushes a bottom wall of the piston defining the cavity. If fuel pressure of a pressure control chamber increases via a pressurization chamber and a communication passage due to pressurization by the piston, a needle moves in a valve-opening direction against a first compression coil spring. Since the piston has the cavity, a movable mass of the piston is reduced while securing axial length of a sliding section. Thus, fuel leak from the sliding section between the piston and the piston guide cylinder can be suppressed, and an inertial resistance caused in the piston can be reduced.
