摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of reducing a generation amount of particulate matter generated in burning of fuel.SOLUTION: A recession 33 is provided on an outer wall 303 of an injection nozzle 30 having a plurality of injection holes 31. An outside opening 313 of the injection hole 31 is formed on a bottom surface 331 of the recession 33. A side surface 332 of the recession 33 is formed to rise from the bottom surface 331. When fuel is injected by the fuel injection valve, a part of the injected fuel adheres to the vicinity of the outside opening 313 of the bottom surface 331. The adhering fuel moves along the bottom surface 331 and stays in an outer peripheral end 333 of the bottom surface 331. When the fuel injection valve performs next fuel injection, the fuel staying in the outer peripheral end 333 is blown off by the jet of the injected fuel, and is separated from the recession 33. Thus, an amount of the fuel adhering to the inside of the recession 33 is reduced. Accordingly, it is possible to reduce a generation amount of particle matter generated by burning of the adhering fuel.
摘要翻译：要解决的问题：提供一种能够减少燃料燃烧产生的颗粒物质的产生量的燃料喷射阀。解决方案：在具有多个喷射孔31的喷射喷嘴30的外壁303上设置有凹部33 喷射孔31的外侧开口313形成在凹部33的底面331上。凹部33的侧面332形成为从底面331上升。当燃料被燃料喷射阀喷射时，喷射的燃料的一部分附着在底面331的外侧开口313附近。附着的燃料沿底面331移动并停留在底面331的外周端333内。当燃料喷射阀执行接下来的燃料喷射，停留在外周端333中的燃料被喷射的燃料的喷射物吹出，并且与凹陷33分离。因此，附着在凹部内侧的燃料量在33减少。因此，可以减少由附着的燃料燃烧产生的颗粒物的产生量。

摘要： PROBLEM TO BE SOLVED: To provide a high pressure fuel pump not causing the enlargement of an electromagnetic drive part by reducing a force required by an elastic member for keeping a valve member separate from a valve seat. SOLUTION: When the valve member 41 is separated from a valve seat 32, the movement of the valve member 41 is restricted by abutting on the stopper 42. A cylindrical part 45 of the valve member 41 is closed by the stopper on an end at the opposite side of a bottom 44. Consequently, fuel of which the pressure rises in a pressurizing chamber 113 does not flow in the cylindrical part 45 when fuel is returned to a fuel chamber 16 from the pressurized chamber 113. A collision of fuel with the bottom 44 of the valve member 41 is thereby mitigated and the valve member 41 is not pushed in to a valve seat 32 side by the flow of fuel. As a result, a pressing force of a spring 56 pressing the valve member 41 to keep the valve member 41 separate form the valve seat 32 is reduced, and the enlargement of the spring 50 and the electromagnetic drive part 50 can be inhibited.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection nozzle capable of inhibiting the generation of cavitation, preventing the lowering of injection amount, and securing fuel spray travel.
SOLUTION: A nozzle body 2 has a group of injection holes having a first micro injection hole 6a and a second micro injection hole 6b on an inner peripheral face of a suction chamber 8, the micro injection holes 6a, 6b are arranged in parallel in the central axis direction of the suction chamber 8, and have the taper-shape of which a diameter is gradually reduced from an inlet toward an outlet of the injection hole 6. A tip part of a needle 3 is provided with a first conic face 11 and a second conic face 12 respectively on upstream and downstream sides of a sheet part 10, and angular differences α1, α2 between each of the conic faces 11, 12 and a sheet face 7 is determined to be larger than that of a conventional nozzle. According to this constitution, as a flow speed of the fuel flowing on the sheet face 7 can be reduced, the generation of cavitation can be reduced. As a result, the fuel in a gas state flowing inside of the injection holes can be reduced, which prevents the lowering of the injection amount.

摘要： PROBLEM TO BE SOLVED: To provide a fluid control valve capable of opening and closing by small driving force with a simple construction.SOLUTION: A balance rod 11 provided slidably with a needle 30 forms a low-pressure chamber 27 in communication with a core chamber 34 formed inside a housing 20. A needle chamber 32 capable of communicating with a nozzle 242 is formed between a nozzle part 24 and a valve part 303. The needle chamber 32 communicates with the core chamber 34 via a throttle flow passage 28. When opening of the valve, if balance between acting force acting on the needle 30 in a valve closing direction and acting force acting on the needle 30 in a valve opening direction, which are caused by pressure of fuel, changes as compared with when closing of the valve, the needle chamber 32 and the core chamber 34 exchange fuel via the throttle flow passage 28. With this, the acting force acting on the needle 30 in the valve opening direction and the acting force acting on the needle 30 in the valve closing direction, which are caused by pressure of fuel, can be balanced in the same relationship either when closing of the valve or when opening of the valve.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve allowing a fuel injection rate to be changed with simple structure.SOLUTION: A needle 40 formed of a magnetic material includes a body 41, a seal part 42, and a needle large-diameter part 44. When the seal part 42 abuts on a valve seat 312, a distance d1 is formed between an end face 61 of a fixed core 60 and a second stepped face 49 of the needle large-diameter part 44, and a distance d2 smaller than the distance d1 is formed between the end face 61 and an end face 57 of an annular projected part 56 of a movable core 50. When power supply is started on a coil 70, the movable core 50 and the needle 40 are attracted to the fixed core 60, the end face 57 abuts on the end face 61 first, and the needle 40 is lifted by the distance d2. When more current flows in the coil 70, the second stepped face 49 abuts on the end face 61, and the needle 40 is lifted by the distance d1. An fuel injection rate is controlled thereby in a fuel injection valve 1.

摘要： PROBLEM TO BE SOLVED: To reduce manufacturing man-hours by reducing the finishing accuracy of a needle 2 and a member supporting the needle 2 in an injector 1 having a piston 6 moving forward and backward according to the expansion and contraction of an actuator 4 and a first shaft part 13 receiving fuel pressure increased and decreased by the movement of the piston 6 in a valve open direction arranged in series in an axial direction.
SOLUTION: In this injector 1, a first shaft part 13 is slidably supported by a first sleeve 7 loosely inserted in a first inner chamber 17, and a second shaft part 14 is freely slidably supported by a body 10. Consequently, the first and the second shaft parts 13, 14 are supported by mutually different members and relatively large clearance is formed at an outer circumference side of the first sleeve 7. Consequently, it is not necessary to accurately work the needle 2, the first sleeve 7 supporting the needle 2 and a vicinity of a second inner chamber 18 in the body 10.
