ABSTRACT:
A method of producing and radiating ultrasonic energy in fluids, in particular for irradiating cleaning baths, having an ultrasonic generator and a converter or transducer associated therewith, is improved with respect of its mode to operation and efficiency by a resonator being immersed in the fluid and the fluid being irradiated by radial components which are produced in the expansion nodes of longitudinal waves of the resonator. A corresponding apparatus with an ultrasonic generator, in accordance with the invention, has a resonator (1) which is connected to a sound transducer (9) towards the fluid or the bath (7) and which is tuned in its longitudinal axis (M) to an integral multiple of the acoustic operating half-wave length.lambda./2, to produce transverse compressions at the expansion nodes thereof. The resonator (1) is preferably in the form of a hollow profile of round cross-section and may possibly also contain further resonators.
