Abstract

Patente de Invenção: <B>"OSCILADOR FLUìDICO LIVRE DE REALIMENTAçãO E MéTODO"<D>. A presente invenção trata de um oscilador fluídico que inclui um membro dotado de uma câmara de indução de oscilação (IC), pelo menos uma fonte de fluido (SF) sob pressão, pelo menos um par de bocais de força (FH1, FH2) conectado a pelo menos uma fonte de fluido sob pressão para projetar pelo menos um par de jatos de fluido dentro da câmara de oscilação, e pelo menos uma saída a partir da câmara de oscilação para emitir um jato pulsante de fluido para o ponto de utilização ou ambiente. Uma tubulação de fluído comum conectada ao referido pelo menos um par de bocais de força. O formato da tubulação de bocal de força forma uma das paredes de interação ou câmara de oscilação. Em alguns dos circuitos fluídicos, o comprimento pode ser correspondido ao encaixe dos alojamentos existentes. O bocal de força pode ter deslocamentos que produzem ângulos de dispersão em um ângulo de ventilação de pulverização líquida para a esquerda ou para a direita dependendo da direção desejada. Em algumas modalidades, a garganta de saída é deslocada em relação ao eixo geométrico (deslocada em relação ao eixo geométrico central de simetria) em uma pequena fração à esquerda ou à direita para mover para a esquerda ou para a direita o ângulo de dispersão na pulverização. A garganta de saída (BX) pode ser deslocada ao longo do eixo geométrico longitudinal por uma pequena quantidade para produzir um ângulo de dispersão de determinado grau para a esquerda ou para a direita dependendo do que é desejado. Assim, pode-se construir circuitos para dispersão ao se usar a combinação de técnicas descritas acima que se adequa a maior parte das aplicações.
