ULTRASONIC ATOMIZING APPARATUS

摘要

The apparatus e.g. for atomizing fuel in an internal combustion engine includes an ultrasonic vibration generating means and an ultrasonic vibrator horn (10) connected at one end to said ultrasonic vibration generating means. The horn has, at its other end, an end portion (1a) flared and enlarged in diameter towards the tip end of the horn. The apparatus is adapted to atomize liquid fuel on the outer surface (2) of said flared portion as the fuel is supplied from supply means (21,22) onto said surface. A hollow recess (3) is provided in the flared portion and opens towards the tip end of the horn. The geometry of the hollow recess (3) is such that the hollow recessed section of the horn has an approximately constant area of transverse cross-section taken in any plane perpendicular to the longitudinal axis of the horn.
