Claims

[Scope of utility model registration request]

An ultrasonic vibration generating element, a vibrator having the ultrasonic vibration generating element attached to one end and an atomizing part at the other end, and a fuel conduction path that is concentric with the vibrator and opens near the atomizing part. a plug that cooperates with a cylindrical valve seat to displace a minute predetermined section; a spring means that presses the plug against the valve seat; and abutting the other end of the spring means;
An ultrasonic fuel having a housing that liquid-tightly accommodates an adjusting means for adjusting the pressing force of the spring means and an electromagnetic means for attracting the plug against the spring force of the spring means, and is provided with a fuel supply port. In the injection nozzle, the adjusting means includes a cylindrical body having a worm wheel threaded on the outer periphery on the side that contacts the spring means and coaxial on the other side, and a worm that meshes with the worm foil, and the housing. An ultrasonic fuel injection nozzle, characterized in that the worm is rotated through an adjustment port opened on the worm shaft to move the cylindrical body up and down, and the adjustment port is sealed after the rotation adjustment.
