Abstract

Es objeto de la presente invención un dispositivo para la generación de burbujas destinadas a incorporarse principalmente a la capa límite turbulenta de la superficie mojada del casco de una embarcación en movimiento integrado por un sistema multi-celda adherido a las paredes del casco de dicha embarcación; dicho sistema dispone al menos de un eje de circulación principal recorridos por dos conductos de distribución, un conducto (1) de agua a presión (preferentemente procedente del medio acuático de navegación) y otro conducto (2) de un gas a presión (preferentemente aire), que alimentan, en forma secuencial, paralela o en combinación, a múltiples celdas eyectoras de burbujas.
