FUEL INJECTION VALVE AND FUEL INJECTION DEVICE |
摘要 |
<p>It is equipped with an injector body 4z which has formed therein high-pressure paths 6az, 6bz, and 6cz through which high-pressure fuel flows to a spray hole and stores therein a piezo-actuator 2z (i.e., an opening/closing mechanism) and a back-pressure control mechanism 3z (i.e., an opening/closing mechanism) which open or close the spray hole, and a fuel pressure sensor 50z installed in the body 4z to measure the pressure of the high-pressure fuel. The body 4z has formed therein a branch path 6ez diverging from the high-pressure paths 6bz and 6cz to deliver the high-pressure fuel to the fuel pressure sensor 50z.</p> |
