Abstract

REGULADOR DE FLUXO DE FLUIDO. Trata-se de um regulador de fluxo de fluido (20) que compreende: uma porta de entrada de fluido (34) e uma porta de saida de fluido (54); pelo menos um canal de controle de fluxo de face aberta (60) definido por um fundo planar (62) e por duas paredes laterais (64) que se comunicam com a porta de saída (54) em uma junção (66) e tem uma seção transversal que diminui com a distância a partir da junção; um diafragma elástico (40); uma prateleira de suporte (58) na qual é assentado o diafragma (40) e que suporta o diafragma (40) ao longo de um contorno planar paralelo ao fundo de cada um de pelo menos um canal (60); em que, para regular o fluxo de fluido, com uma pressão de fluido de entrada crescente o diafragma (40) cobre as partes da face aberta que são mais distantes da junção (66) em uma região onde a seção transversal diminui com a distância a partir da junção (66).
