Abstract (en)
[origin: DE19626428A1] In a pump chamber (1) connected to a liquid supply, an overhanging piezoelectric flexural transducer (4) is disposed so that when voltage pulses are applied to produce an excursion, a number of droplets can be expelled from a nozzle array (3) in the housing wall (2c) of the pump chamber (1) using a plurality of nozzles (32). Gaps (5b) are formed between the edges lateral to the direction of overhang and the free end (4d) of the piezoelectric flexural transducer (4) and adjacent sections of the housing wall. The nozzle array (3) can be disposed in the projection of the plate surface of the piezoelectric flexural transducer (4) in its direction of motion or in the extension of the piezoelectric flexural element (4) or in another suitable position. As part of a combustion device the droplet mist generator is excellent for producing a combustible fuel-oxidant mixture.
