摘要： PROBLEM TO BE SOLVED: To increase a flow coefficient in a low lift region in a fuel injection valve where the entrance side opening of a nozzle hole is opened on the sack peripheral wall surface.SOLUTION: A body groove section 23 that is extended to the inlet side opening of the nozzle hole 22 from the downstream side more downstream than a body sheet section and is connected to the nozzle hole 22 is formed on a body sheet surface 20 and the sack peripheral wall surface 210. In the low lift area, the fuel passing through a needle sheet section 13 flows into a sack section 21 is temporarily separated from the bottom of the body groove section 23 in an upstream area b in the body groove section 23 by being pulled to the wall surface of a needle second taper surface 12. However, the fuel flowing inside the body groove section 23 is spread on the bottom side of the body groove section 23 as the flow velocity of the fuel decreases, the fuel is adhered to the bottom of the body groove section 23 in the downstream area c in the body groove section 23 (i. e., the separation disappears), and thereby the fuel smoothly flows from the body groove section 23 to the nozzle hole 22.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection device whose injection performance less deteriorates with the elapse of time by suppressing the wear of members.
SOLUTION: A pressure control chamber 81 urges a needle 3 to be unseated when the pressure of inside fuel rises. A pressure chamber 82 is communicated with the pressure control chamber 81 for applying pressure to inside fuel with a piston 5. A piezoelectric driver 6 is elongated with voltage applied thereto to thrust the piston 5 so that pressure in the pressure chamber 82 rises. An ECU 8 changes voltage to be applied to the piezoelectric driver 6 to change pressure in the pressure chamber 82 and the pressure control chamber 81. The ECU 8 has a speed reducing means for reducing the moving speed of the needle 3 to be seated while changing a degree of reducing voltage applied to the piezoelectric driver 6 to change the contraction per unit time of the piezoelectric driver 6 on the way of moving the needle 3 from an unseating position to a seating position.
