Fuel injection valve and fuel supply system equipped therewith for internal combustion engines

摘要

A fuel injection valve for internal combustion engines is disclosed, in which transducer is vibrated by an electrostrictive device, and the fuel is atomized by a vibration surface at the part of the transducer where the amplitude thereof is maximum. The transducer has a path or transporting the fuel to the vibration surface. The fuel transport path may have midway thereof a valve member with a valve seat adapted to rise for opening the transport path when a predetermined vibration is exerted on the transducer.
