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 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.
摘要翻译：一种用于防毒面具的过滤罐组件，其包括具有适于从空气中去除气溶胶，颗粒材料和液滴的第一过滤介质的初级罐，以及包括适于除去有毒气体并且与第一罐中的第一过滤介质。补充过滤罐具有适于拦截有毒工业材料的第三过滤介质，并且可移除地安装到第一壳体的第一端，以补充初级过滤器罐过滤有毒工业气体的能力。

摘要： A respirator speech transmitter and exhalation valve module comprising a resilient exhalation valve having a low airflow resistance for exhalation but providing a secure seal against inadvertent inhalation through the exhalation valve module. An exhalation airflow channel is formed between a module body on the outside of the channel and a conical airflow guide and the exhalation valve on the inside of the channel. The exhalation airflow channel is in the form of an amplification horn. The airflow channel produces a smooth airflow for unrestricted exhalation and high intelligibility of a user's speech. The module includes a drinking conduit for selectively fluidly connecting a mouthpiece in the respirator to a beverage container and further includes an electrical communication block with internal and external fittings for connecting a microphone in the mask to a radio or amplifier carried by the mask user.
摘要翻译：一种呼吸器语音发射器和呼气阀模块，包括具有低呼气阻力的弹性呼气阀，用于呼气，但提供了安全的密封，以防止通过呼气阀模块的无意吸入。在通道外侧的模块主体与通道内侧的锥形气流引导件和呼气阀之间形成呼气气流通道。呼气气流通道为放大喇叭的形式。气流通道产生平稳的气流，用于不受限制的呼气和用户演讲的高清晰度。模块包括用于选择性地将呼吸器中的接口流体连接到饮料容器的饮用管道，并且还包括具有用于将掩模中的麦克风连接到由掩模使用者携带的无线电或放大器的内部和外部配件的电气通信块。
