Abstract

RESPIRADORES. A presente invenção refere-se a um conjunto de válvula de exalação para um respirador, o dito conjunto compreendendo uma válvula de chapeleta unidirecional a montante (1) e uma válvula de chapeleta unidirecional a jusante (2), ambas montadas no interior de um alojamento (3,4,5). As válvulas (1,2) são mutuamente espaçadas para definirem entre si um volume (25) que atua como volume (35) que atua como um "espaço morto" no qual uma parte do ar recém exalado repousará para que, caso a válvula a montante vaze por qualquer razão, qualquer ar de escape de volta para o interior do respirador será tomado deste ar recém exalado, e não será assim contaminado pelo ar ambiente.
