摘要： PROBLEM TO BE SOLVED: To obtain a desired fuel flow even when an included angle of a nozzle hole is not formed corresponding to a prescribed included angle caused by the machining allowance or the like, by connecting a main well in the downstream from a sheet part of a valve element, to the nozzle hole through a fuel metering passage comprising an uniform passage section. SOLUTION: A nozzle hole 74 is extended in a state that it is inclined to a central axis of a fuel injection valve body 71 at a prescribed angel θ1, a height(H) of the nozzle hole 74 is almost uniform at every position, a width of the nozzle hole 74 is gradually narrowed toward the inside with a prescribed included angle, and a width(W) of an external opening of the nozzle hole 74 is larger than the height(H). A side face 74a in the height direction of the main well 72c side of the nozzle hole 74 and the fuel tank 72c are connected by a fuel metering passage 75 having an uniform passage section, whereby the desired fuel flow can be obtained even when the included angle of the nozzle hole 74 is not formed corresponding to a prescribed included angle caused by the machining allowance or the like.

摘要： PURPOSE:To raise durability of a piezoelectric element, reduce cost by means of a small sized field control means for controlling field application to piezoelectric element, and, when there occurs an abnormality to a piezoelectric element, etc., so that a valve element does not move up to a maximum lift position, positively confirm this fact. CONSTITUTION:A piezoelectric type impact sensor 9 in a fuel injection valve V for detecting contact of a needle valve to a stopper 10. When the needle valve 5 reaches to a maximum lift position so that the sensor 9 detects mutual contact of both two 5, 10, the voltage applied to the piezoelectric element 12 is reduced by a specific value a and so the needle valve 5 is slightly separated from the needle stopper 10. Then, when both two 5, 10 do not come in contact, the voltage applied to the piezoelectric element 12 is raised by a specific valve alphaand so the needle valve 5 is brought in contact with the needle stopper.

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic fuel injection valve through which desired amount of fuel can be accurately injected. SOLUTION: A needle valve 2 for closing a fuel injection hole 3 is opened and closed by electromagnetic force. A pressure receiving surface 11 for receiving fuel pressure is formed on the needle valve 2 so that the needle valve 2 makes the fuel injection hole 3 open. Fuel supply passages 8a, 8b are formed so that fuel can simultaneously be supplied to the pressure receiving surface 11 and the fuel injection hole 3. Sectional area of the fuel supply passages 8a, 8b can be adjusted. When the needle valve 2 must open the fuel injection hole 3, the sectional area of the fuel supply passages 8a, 8b is increase. When the needle valve 2 must close the fuel injection hole 3, the sectional area of the fuel supply passages 8a, 8b is reduced.

摘要： PROBLEM TO BE SOLVED: To obtain an optimum spraying angle according to a pressure inside a cylinder by varying swirl flow strength. SOLUTION: A valve seat 5, which is opened or closed by a needle valve element 3, is disposed upstream of an injection hole 4 on a fuel passage 11. A swirl generating chamber 13 is formed on the outer periphery of the valve element 3 upstream of the valve seat 5. In a fuel introducing-in hole 14 for forming a swirl flow for supplying the fuel to the swirl generating chamber 13 from a fuel supply path 12, a fuel inlet hole 15 is formed on a stationary cylinder 2 provided on the outer periphery of the swirl generating chamber 13. A fuel outlet hole 16 of the fuel introducing-in hole 14 is formed on a movable cylinder 9 disposed on the outer periphery of the swirl generating chamber 13. When a pressure sensor (an interlocking sensor 18 or the like) senses a pressure inside the cylinder so that the movable cylinder 9 is turned, a cross-sectional area of a communication opening S defined between the fuel inlet hole 15 and the fuel outlet hole 16 is changed, so that a pressure loss of the fuel introducing-in hole 14 is varied according to a difference in cross-sectional area of the communication opening S, thus varying swirl flow strength.

摘要： PURPOSE:To reduce the volume of the pressure control chamber of a fuel injection valve and enlarge a stopper area by extending the extending part of a needle up to a position opposing to the throttle part of the pressure control chamber. CONSTITUTION:An extending part 27 which extends toward the throttle part 16 of a pressure control chamber 15 while inserting the inner diameter side of a push spring 17 in a needle 13, and a needle stopper 18 is formed on the wall surface around the throttle part 16 of the pressure control chamber l5. Since the push spring 17 is provided outside the pressure control chamber 15 and an extending part 27 is projected in the pressure control chamber 15, the volume of the pressure control chamber 15 is reduced. The inner diameter of the throttle part 16 is reduced, so that a stopper area can be increased regardless of the push spring 17.
