Abstract

UNIDADE DE TROCA DE CALOR E UMIDADE COM VÁLVULA DE RETENÇÃO. Uma unidade HME (50) incluindo um alojamento (52), um meio HME (54) e uma montagem de válvula de retenção (56). O alojamento (52) forma uma primeira porta (58), uma segunda porta (60) e uma seção intermediária (62) definindo primeiro e segundo caminhos de fluxo conectando de forma fluídica as primeira (58) e segunda portas. O meio HM (54) é mantido dentro da seção intermediária (62) ao longo do segundo caminho de fluxo. A montagem de válvula de retenção (56) inclui um elemento de obstrução (80) posicionado de forma móvel dentro da seção intermediária (62) para fornecer seletivamente posições aberta e fechada. Na posição aberta o primeiro caminho de fluxo está aberto em relação ao elemento de obstrução (80). Na posição fechada o elemento de obstrução (80) fecha o primeiro caminho de fluxo. Em um modo o elemento de obstrução (80) faz transição para a posição aberta em resposta a fluxo de gás em uma direção de fluxo da segunda porta (60) para a primeira porta (58), e faz transição para a posição fechada em resposta a fluxo de gás em uma direção de fluxo oposta.
