Fuel injecting device for internal combustion engine i.e. diesel engine, has control piston for closing control chamber supplied with high pressure fuel by inlet nozzle, where inlet nozzle presents variable fuel passage section
The device has a control piston for controlling a closing needle of an injection tip. The control piston closes a control chamber (32) supplied with high pressure fuel by an inlet nozzle (32A), where the inlet nozzle presents a variable fuel passage section. The piston is projected into an outlet nozzle. A closing element closes a part of the fuel passage section. The inlet nozzle has a cylindrical pipe (33) made of radially deformable piezoelectric material.
