FUEL INJECTION VALVE AND FUEL INJECTION DEVICE WITH THE SAME

Japanese Patent JP2009138580

A

To provide a fuel injection valve of a simple configuration mainly injecting high-pressure gas fuel and capable of using as injection fuel high pressure liquid fuel introduced as hydraulic oil and to provide a fuel injection device with the fuel injection valve and selectively injecting the high pressure gas fuel and the high pressure liquid fuel according to an operation situation.

The fuel injection valve 10 includes a high-pressure gas fuel introduction path 362 for introduction of the high-pressure gas fuel GF, a high-pressure liquid fuel introduction path 250 for introduction of the high-pressure liquid fuel LF, a fuel chamber 408 provided in a nozzle part 11, a first flow path bringing the high-pressure gas fuel introduction path 362 and the fuel chamber 408 in communication with each other, a second flow path bringing the high-pressure liquid fuel introduction path 250 and the fuel chamber 408 in communication with each other and a flow path switching valve 400 switching the first flow path and the second flow path.
