Abstract (en)
The atomiser head (1) has several primary conduits (11) whose atomising orifices (12) are regularly located around a circular crown. The different primary conduits are supplied with liquid from a single supply channel (4). Each primary conduit is associated with two secondary conduits (13,14) connected to a pressurised auxiliary gas supply. The gas is supplied from a single annular channel (9) concentric with the liquid supply channel. The auxiliary gas is injected laterally into the primary conduits in two longitudinally separated places, upstream of the atomising orifice and perpendicular plane to the primary conduit axis. The axes of the two secondary conduits make angles between zero and 90 degrees with the primary conduit axis. The primary and secondary conduits have a transverse dimension equal to 1mm <IMAGE>
Abstract (fr)
L'invention concerne un dispositif de pulvérisation d'un liquide, notamment d'un liquide à haute viscosité, à l'aide d'au moins un gaz auxiliaire sous pression, ce dispositif comprenant une pluralité de premiers conduits (11), alimentés en liquide à pulvériser, ces premiers conduits comprenant chacun un orifice de pulvérisation (12). Selon l'invention, à chaque premier conduit (11) sont associés deux seconds conduits (13,14) connectés à une source de gaz auxiliaire sous pression, ces deux seconds conduits (13,14) débouchant latéralement dans le premier conduit (12) en deux emplacements distincts. <IMAGE>
