Title: Fuel injection valve of engine
Inventor: KATSU MASAHIKO
IPC: F02M47/00
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent temporary fuel injection at the time of breaking of wire by contracting an actuator by interrupting voltage impression on the actuator, reducing volume of a pressure chamber in company with energizing force, causing rapid pressure increase into pressure chamber and rapid pressure increase in a differential pressure chamber via a communicating path, resulting in closing of a valve against the fuel pressure. SOLUTION: When opening a valve, a piezoactuator 10 is driven to elongate against a return spring 22 according to voltage impressed by synchronizing with an engine revolution. When closing the valve, the piezoactuator is contracted by interrupting voltage impression on the piezoactuator 10. According to this contraction, volume of a pressure chamber 7 is reduced by energizing force of the return spring 22 and the pressure in the pressure chamber 7 rapidly increases. The pressure in a differential pressure chamber 8 which is communicated with the pressure chamber 7 via a communicating path 17 rapidly increased, energizing force of the return spring 4 is added and a needle valve 2 is closed against fuel pressure of a fuel pressure chamber 3. Thus, fuel injection can be prevented because valve closing operation is performed when voltage impression is interrupted due to breaking of wire.
