Abstract

Un respirador antipolvo, que esencialmente está constituido por un dispositivo de careta de goma moldeada, propio para aplicarse por la parte baja de la nariz y la boca del usuario, prolongándose dicha careta hacia adelante para terminar en un receptáculo que lleva alojada una esponja entre el fondo de este receptáculo y un borde interno de goma; llevando dispuesta la propia careta una válvula para espiración del aire respirado, compuesta de una cápsula con su fondo perforado y una serie de orificios en la pared lateral practicados cerca de dicho fondo, teniendo esta cápsula alojado un obturador de laminilla entre el propio fondo y un borde de goma que impide el paso del aire aspirado y permite con facilidad la salida del espirado.
