Abstract

992,031. Liquid-fuel burners. ESSO RESEARCH & ENGINEERING CO. Feb. 22, 1962, No. 6938/62. Heading F4T. [Also in Divisions B2, H3 and H5] A mechanical vibrator for atomizing liquids, e.g. a fuel oil, comprises a piezo-electric plate 10 clamped between conducting mechanical resonators 12, 14, a channel being provided through one resonator 12 whereby liquid may be fed to an orifice situated at a displacement antinode of the resonator. In the arrangement shown the two resonators are both made of aluminium and have the same shape though resonators of different shapes and metals may be used provided they are both resonant at the same frequency, corresponding to the resonant frequency of the crystal. The resonators shown are of stepped cylindrical form, the steps being situated at a displacement node so that they may be clamped at that position. Clamping is effected through a narrow raised rim 36, 38 on endplates 24, 26 held together by bolts 28. Insulating layers, e.g. of polyethylene terephthalate, are placed between the raised rims and the respective resonators. The piezo-electric plate, which may be composed of a ceramic such as barium titanate, lead zirconium titanate or lead zirconate, may be silvered to improve the electrical contact between the plate and the resonators 12, 14 to which leads for applying an energizing voltage are connected. To improve the acoustic coupling between the plate 10 and the resonators 12, 14 a layer of polydimethyl siloxane in the form of silicone bouncing putty may be applied to each surface of the plate 10 (Fig. 4, not shown). The silicone putty may include finely divided silver to improve its electrical conductivity. The Specification also describes prior-art atomizing arrangements in which a ceramic piezo-electric plate is bonded by an epoxy-resin cement to the larger diametral surface of a truncated conical resonator, the concentration of energy at the tip of the resonator being sufficient to cause atomization of a liquid applied thereto.
