射弁。 A nozzle hole is formed at one end of the fuel injection valve housing, a piezoelectric element is arranged at the other end of the housing, and the opening and closing of the nozzle hole is controlled by the outer end of a needle slidably inserted into the housing. In the fuel injection valve, a piston with a diameter larger than the needle is slidably inserted into the housing to form a pressurized chamber between the inner end of the needle and the piston, and a lightweight space is formed between the piston and the piezoelectric element. A fuel injection valve for an internal combustion engine that is mechanically connected by a rod made of material.
