  • Fuel supply unit and assembling method thereof
    Patent number: 6874478
    Abstract: A fuel supply unit includes a fuel distribution pipe, a fuel injector and a locking clip. The fuel distribution pipe has a fuel outlet port, and the fuel injector has a fuel inlet port. The fuel inlet port is communicated with the fuel outlet port. The locking clip is for preventing the fuel injector from detaching from the fuel distribution pipe. The fuel injector has a projecting lockable injector portion in a circumference thereof. The locking clip has a locking portion extending along a circumference of the injector within a circumferential length thereof. When the fuel injector is moved in a direction of detaching the fuel inlet port from the fuel outlet port, the locking clip locks the fuel distribution port, and a middle portion of the locking portion locks the lockable injector portion. Therefore, the locking clip prevents fuel injector from detaching from the fuel distribution pipe.
