Patent ID: 8402949

Claim:
A fuel injector for an internal combustion engine comprising: a metallic body in which a fuel flow path is formed which extends from a fuel inlet to a spray hole; an actuator disposed within said metallic body, said actuator working to open the spray hole to spray fuel, as supplied to the fuel flow path through the fuel inlet, to an internal combustion engine; a fuel pressure sensor installed in said metallic body, said fuel pressure sensor working to measure a pressure of the fuel in the fuel flow path and produce an electric signal indicative thereof; a circuit component serving as an amplifier to amplify the electric signal, as produced by said fuel pressure sensor to output the electric signal; and a thermal insulating member disposed between the said metallic body and the circuit component to shield said circuit component thermally, wherein said thermal insulating member has the circuit component mounted thereon and also has retained therein connector terminals leading electrically to the circuit component, and wherein said thermal insulating member, the connector terminals, and the circuit component are united as an assembly.
