摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve for controlling nozzle back pressure with a hydraulic control valve, capable of improving injection stability by restraining hydraulic pulsation accompanied with discharge of compressed fuel and stably operating a hydraulic control valve, and facilitating addition of hydraulic oil to a displacement increasing chamber from a check valve.
SOLUTION: During injection, a piezo actuator 2 is stretched to drive a small-diameter piston 32, push down a valve body 4 and drop pressure in a control hydraulic chamber 6 through a large-diameter piston 31 and the displacement increasing chamber 3. At this time, compressed fuel in the control hydraulic chamber 6 flows out to a spill chamber 44 through a valve chest 42, but immediately flows out to a drain passage 131 through a spring chamber 34 from the spill chamber 44 using a plurality of communication passages 74 formed by a flat cut 73 on the outer-periphery wall of a cylinder body 7, thus stabilizing injection and facilitating addition of leak fuel.

摘要： PROBLEM TO BE SOLVED: To satisfy both of the slow opening and quick closing of a fuel injection valve by way of a nozzle needle by slowing down a decrease and speeding up an increase in the oil pressure of a control room for operating the nozzle needle of the valve.
SOLUTION: The fuel injection valve comprises a three-way valve 4 for selectively providing fluid communication between a control chamber 3, which applies a valve closing force to a nozzle needle 2 for opening/closing an injection hole 13, and a drain channel 17 or a high-pressure channel 15 for providing fluid communication between the valve chamber 42 of the three-way valve 4 and the control chamber 3 through a main orifice 61. The fuel injection valve also comprises an auxiliary orifice 62 for providing full-time fluid communication bypassing the three-way valve 4 between the high-pressure channel 15 and the control chamber 3. Driving a valve body 41 by a piezoactuator 5 allows a high-pressure fuel flowing through the auxiliary orifice 62 to slowly reduce the oil pressure of the control chamber 3 when the valve is open, and quickly increases the oil pressure when the valve is closed, so that the nozzle needle 2 is improved in lifting characteristic.

摘要： PROBLEM TO BE SOLVED: To provide a road-vehicle communication system with high reliability.
SOLUTION: In a camera system 10, a communication apparatus 22 for transmitting the vehicle registration number of a vehicle 20 to the outside is incorporated into a number plate 21 on the back of the vehicle 20 so that the apparatus does not easily break down. The vehicle registration number transmitted from the communication apparatus 22 in a communication area T is received with the antenna 30 of the travel road side of the vehicle 20. A first vehicle detection sensor 40 detects that the trailing end part 20b of the vehicle 20 has passed the termination position of the communication area T. Thus, the communication apparatus 22 is considered to have passed through the termination position of the communication area T. When the vehicle registration number from the communication apparatus 22 is not received even if the passage of the trailing end part 20b of the vehicle 20 through the termination position of the communication area T is detected, the vehicle 20 is photographed. Then the vehicle registration number displayed on a number plate 23 is extracted from picture data and the vehicle 20 is specified.
