摘要： A fuel injector for an internal combustion engine is provided which has a fuel supply path and a nozzle chamber. The fuel supply path extends a spray hole. The nozzle chamber is defined in the fuel supply path. A nozzle is disposed within the nozzle chamber to establish or block a fluid communication between the fuel supply path and the spray hole. A fuel pressure sensor is installed in the fuel injector so as to be exposed to the fuel in the nozzle chamber. Specifically, the fuel pressure sensor is located closer to the spray hole than a prior art structure in which the fuel pressure sensor is installed in a fuel supply pipe, thus resulting in increased accuracy in measuring a change in pressure of the fuel arising from the spraying of the fuel from the spray hole.

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.
