Abstract

Abstract Apparatus for atomizing liquids which includes an ultrasonic excitation system, a bending resonator which oscillates at ultrasonic frequencies, and an amendment for the delivery of liquid into the velocity nodal region of the bending resonator. The bending resonator has at least one surface which is inclined with respect to the axis of the excitaton system. The bending resonator can be in the form of an elongated narrow strip having a plurality of parallel nodal lines. The length of the excitation system is approximately (2n+1) λ/4, wherein n is 0 or an integer.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 55 words
Apparatus for atomizing liquids comprising an ultrasonic excitation system, a bending resonator which oscillates at ultrasonic frequencies, and means for the delivery of liquid into the speed nodal regions of the bending resonator, characterized in that the bending resonator is in the form of an elongated narrow strip having a plurality of parallel nodal lines.
Claim 2
Dependent Claim 55 words
Apparatus for atomizing liquids comprising an ultrasonic excitation system, a bending resonator which oscillates at ultrasonic frequencies, and means for the delivery of liquid into the speed nodal regions of the bending resonator, characterized in that the bending resonator is in the form of an elongated narrow strip having a plurality of parallel nodal lines.
Claim 3
Dependent Claim 37 words
Apparatus as claimed in claim 1 wherein, any desired inclination of the normal to the surface of the bending resonator, and thus the atomization direction, can be set by varying the axial direction of the excitation system.
