Abstract

"CIRCUITO DE PROTEçãO RESPIRATóRIA, E, MéTODO PARA REGULAR FLUXO DE AR ATRAVéS DE UM DISPOSITIVO DE REGULAGEM DE AR". Um circuito de proteção respiratória do tipo tendo um regulador de fluxo de ar disposto em um trajeto de fluxo de ar entre um suprimento de ar e um respirador é aperfeiçoado por meio da inclusão de um divisor de fluxo de ar e uma válvula bidirecional. O divisor de fluxo de ar é disposto no trajeto de fluxo de ar a montante do regulador de fluxo de ar, o divisor dividindo o trajeto de fluxo de ar em primeiro e segundo trajetos de fluxo a jusante, com o primeiro trajeto de fluxo a jusante conduzindo para o respirador. A válvula bidirecional é disposta no segundo trajeto de fluxo a jusante, sendo que a válvula bidirecional previne excessivo fluxo de ar a jusante através dela e previne fluxo de ar a montante através dela.
