摘要： A gas mask having a filter canister mount including an inhalation valve and a self-sealing mechanism that prevents air inflow when a filter canister is removed from the canister mount. In one embodiment, the self-sealing valve includes an elastomeric diaphragm mounted in the inlet port and includes a hinge and a skirt, the skirt having a sealing surface that is biased into contact with a valve seat. The filter canister includes a projection adapted to act on the hinge to pivot the skirt away from the sealing surface as the canister is fitted to the canister mount. In one embodiment, the canister comprises a stacked-radial-flow arrangement of particulate and carbon filtration media. In one embodiment, the gas mask includes a visor having a pair of spaced optical panels with a hinge mounted therebetween for relative rotational movement.

摘要： A filter for a gas mask has a concave outlet wall and a convex inlet wall with a particulate filter bed that has a uniform depth and conforms substantially to the shape of the inlet and outlet wall. The side wall can have an elliptical, circular or convex shape to conform to the curvature of the wearer's face, or a planar shape. The filter an be a double particulate filter element and a double adsorption filter element configured for axial airflow therethrough with a bifurcated flow pattern. The adsorption filter element comprises a granulated charcoal, a composite material having carbon particles combined with binder particles, or an immobilized bed of charcoal granules and EVA-coated fibers.

摘要： A filter canister assembly utilizes a sealant deflector to seal a particulate filter to the canister wall, even after the canister is sealed. The canister housing has a wall and an aperture with a particulate filter disposed therein. The particulate filter has an edge adjacent the wall, and is designed for removing particles of contaminants from a fluid, such as air, passed through the canister. A sealant deflector includes a plurality of vanes standing proud of a support substrate, and is situated between the aperture and the particulate filter and forms a permanent part of the canister assembly. The sealant deflector deflects a sealant in liquid state toward the wall to form a seal between the edge and the wall when the sealant is deposited on the sealant deflector while spinning. This deposits a sealant ring sealing the wall to the edge. The sealant deflector is self-centered under the aperture, by a bow-tie shaped structure of four arms extending outward radially from the sealant deflector connected in pairs by curved braces.
摘要翻译：过滤罐组件利用密封剂偏转器将微粒过滤器密封到罐壁上，甚至在罐被密封之后。罐壳体具有壁和孔，其中布置有微粒过滤器。颗粒过滤器具有邻近壁的边缘，并且被设计用于从通过罐的流体（例如空气）中去除污染物颗粒。密封剂偏转器包括多个叶片，其支撑着支撑基板，并且位于孔和微粒过滤器之间并形成罐组件的永久部分。当密封剂在旋转时将密封剂沉积在密封剂偏转器上时，密封剂偏转器将液体状态的密封剂朝向壁偏转以在边缘和壁之间形成密封。这将一个密封环沉积在边缘上。密封剂偏转器通过由弯曲的支架成对连接的密封剂偏转器的径向向外延伸的四个臂的弓形结构而在孔下方自对中。

摘要： A filter canister assembly for a gas mask comprising a primary canister with a first filter medium adapted to remove aerosols, particulate materials and droplets from air and a second filter medium comprising an adsorbent filter medium adapted to remove toxic gases and arranged in serial communication with the first filter medium in the first canister. A supplementary filter canister has a third filter media adapted to intercept toxic industrial materials and is removably mounted to a first end of the first housing to supplement the ability of the primary filter canister to filter toxic industrial gases.
