    摘要： An exhale valve assembly includes a housing, a valve carrier body, a primary valve assembly, a plunger, a lock assembly, and an air pressure activated actuator assembly. The valve carrier body is disposed the housing and has a passageway. The primary valve assembly is mounted to the valve carrier body. A first air flow path passes through the passageway and a second air flow path passes through the primary valve assembly. The plunger is configured to permit a flow through the first air flow path when the plunger is in a first position and to direct a flow through the second air flow path when the plunger is in a second position. The lock assembly is configured to secure the plunger in the first position. The air pressure activated actuator assembly is configured to release the lock responsive to a pressure change within the cavity of the housing.

    摘要： The present invention provides an improved filter connection system for a gas mask, comprising: a filter, a mounting means that attaches the filter to the gas mask, and a retainer means to hold the filter within the mounting means. The mounting means includes a protruding means; a valving assembly in communication with the protruding means, wherein the valving assembly enables air to flow from the fitter to the mask when the retainer means retains the protruding means, and disables air flow from the filter to the mask when the protruding means disengages from the retainer means; and a sealing means located within or adjacent to the valving assembly to prevent air from outside of the filter from entering the mounting means.

    摘要： A directional valve (10) includes a valve housing (12), a plurality of valve flaps (16-18), which can be moved by a gas stream or by a flowing medium and are arranged at the edge, and a number of support surfaces (20-22) as a valve seat. A number of support surfaces (20-22) corresponds to a number of valve flaps (16-18). Each valve flap (16-18) is adapted to a surface of a respective support surface (20-22). The support surfaces (20-22) are sloped in relation to a cross-sectional surface through the valve housing (12). The support surfaces (20-22) together form a tip pointing in the flow direction of the directional valve (10). A method for manufacturing such a directional valve (10) is provided including method features relating to the use of such a directional valve (10).

    摘要： An earless filter mask includes an inner fabric layer, a filter layer, an outer fabric layer, a plurality of buttons, an exhalation valve, and a conforming band. The conforming band is sewn into an upper and a lower edge of the mask through in-seam sleeves with a first exposed portion extending beyond a first tapered end of the mask and a second exposed portion extending beyond a second tapered end of the mask. The conforming band conforms the mask to a shape of a wearer's face and a first tapered end of the mask is removably connected to a second tapered end of the mask at a nape of the wearer's neck.

    摘要： A self-contained breathing device for use in fighting fires comprising a hood for covering a wearer's head, a membrane for sealing the hood to create a breathing chamber inside the hood, and a source of oxygen disposed inside the hood. The source of oxygen is connected to the user by a conduit inside of the hood, and another conduit directs user-exhaled carbon dioxide to the source of oxygen. The breathing device includes a visual indicator inside of the hood that reacts to the presence of a gas within the hood and provides visual feedback to the user based on a quantity of the gas present in the hood.
