Abstract

Un método para la interrupcion controlada de ahorros de líquido para la produccion de gotas substancialmente monodispersas, el método resalta por el hecho de que comprende los pasos de: - alimentar una pluralidad de primeros chorros de líquido (4) que tiene movimiento estacionario hacia una pluralidad de sectores mutuamente independientes y definidos en una superficie perforada (8); - formar una cabeza de líquido (10) en los sectores (7) cerca de la superficie perforada (8); - provocar que el líquido fluya a través de la superficie perforada (8) para formar una pluralidad de segundos chorros de líquido (6); - cambiar periodicamente y con una frecuencia predeterminada el momento o impulso del líquido alimentado hacia un sector predeterminado (7), de modo que al líquido presente en el sector se le imparta una perturbacion de magnitud predeterminada, que consiste de un cambio periodico en la presion cerca de la superficie perforada (8), que se trasmite a los segundos chorros de líquido (6) provocando su interrupcion controlada en una pluralidad de gotas substancialmente monodispersas.
