摘要： An injector having an injector body, in which a housing opening and a communication hale are provided, includes a supporting member fixed to an actuator, which includes a lead-wire supporting portion that supports ends of lead wires and a plate portion formed integrally with the lead-wire supporting portion. A thickness of the plate portion is smaller than that of the lead-wire supporting portion, and multiple trench portions are provided on a surface of the plate portion so that the plate portion can be easily bent. While the supporting member passes through the housing opening, the lead wires straight move. After an end portion of the supporting member contacts the communication hole, external force is applied to the end portion to bend the plate portion, and thereby the lead wires are bent while moving in the communication hole.

摘要： An injector has a body that defines a high-pressure passage for passing high-pressure fuel to an injection hole inside, a needle that is accommodated in the body and that opens and closes the injection hole, an electric actuator that causes the needle to perform the opening and closing action, a lead wire that is arranged in a lead wire insertion hole formed in the body and that supplies an electric power to the electric actuator, and a fuel pressure sensor that is fixed to the body and that senses pressure of the high-pressure fuel. An outlet hole, via which the lead wire extends from the lead wire insertion hole to an outside of the body, is located at a position closer to the injection hole than the fuel pressure sensor is.

摘要： An injector includes a nozzle body, a main body including a supply port on the outer peripheral surface of the main body and a high pressure passage, and a fuel pressure sensor on an outer peripheral surface of the main body to detect fuel pressure. The high pressure passage has a first passage extending from the supply port in a radial direction of the main body, and a second passage extending from a fuel downstream end portion of the first passage toward an injection hole in an insertion direction of the nozzle body. The supply port and the sensor are diametrically opposed to each other. The main body includes a sensor passage, which branches from the high pressure passage to extend from the fuel downstream end portion of the first passage in an imaginary extension of the first passage so that fuel flows into the sensor through the sensor passage.

摘要： A fuel injection valve includes a body, a fuel pressure sensor, and a weld. The body has a passage to introduce high pressure fuel toward an injection hole. The fuel pressure sensor has a strain element and a sensor element so as to detect a pressure of the fuel. The strain element has an elastic deformation by receiving a pressure of the fuel. The sensor element converts an amount of the elastic deformation into a signal. The weld is defined by welding the body and the strain element. The fuel pressure sensor is mounted to the body through the weld.
