摘要： A flat-folding mask includes a filter layer forming a rim. The filter layer has first and second side panels extending from the rim. A substantially centrally located front panel bridges the first and second side panels, the front panel being substantially flat. The filter layer further includes a fused portion that is seamless and spaced from the rim. Triangular pleats may add support to the side walls and increase the effective filtration area of the mask.

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： This Personal Respirator is a respiratory protection air-purifying device. It minimizes the area required in front of the face, especially around the mouth area, by locating the heavier filter cartridge behind the head, resting on the lower neck and shoulders, connected by two filtered air tubes around the head and neck partially counterbalancing the valve chamber directly in front of the mouthpiece, forming a ring around the head with the mouthpiece in the mouth and the exhaust port in the bottom of the valve chamber. The valve chamber has the filtered air intake check type valves opposite each other horizontally, an exhaust check type valve down with short exhaust tube and an oval mouthpiece tube passing through the mouthpiece, into the mouth. The valve chamber is of minimal size with the three check valves and mouthpiece close together thus minimizing the internal dead air space and making the outside dimensions small enough to fit under safety equipment. The respirator has no straps other than a small tethered nose clip and is worn around the head and neck with the filter resting on the lower neck and shoulders, the mouthpiece inserted in the mouth and the nose clip secured on the nose.
摘要翻译：该个人呼吸器是一种呼吸防护空气净化装置。通过将较重的过滤器滤芯放置在头部后方，放置在下颈部和肩部上，通过两个过滤的气管连接在头部和颈部周围部分平衡阀门，从而最小化面部前方，特别是口部周围所需的面积直接在接口管前面形成一个环绕头部的环，口腔中的接口和阀室底部的排气口。阀室具有水平相对的过滤进气检查型阀，具有短排气管的排气检查型阀和穿过接口的椭圆形口管进入口中。阀室的尺寸最小，三个止回阀和接口紧密靠在一起，从而最小化内部空气空间，并使外部尺寸足够小以适合安全设备。呼吸器除了一个小的系带鼻夹以外没有带子，并且戴在头颈部上，过滤器位于下颈部和肩部上，插嘴插入嘴中，鼻夹固定在鼻子上。

摘要： The breathing system includes an elastic, non-porous body housed within an outer protective shell. The body terminates at its forward end in a protective cap and an air inlet passage and at its inner face in oral and nasal cavities. An air filter is disposed in the body and a mouthpiece, including a bite block, is provided for communicating filtered air into the individual's mouth. The bite block has converging surfaces for biasing the mask toward the individual's face when the individual bites down on the block. A hood attached to the mask surrounds the individual's head and receives exhaled air through exhalation ducts communicating between the mouthpiece and the hood.

摘要： An on-off valve mounted in a high pressurized gas container, which has a holding portion for holding a flow amount controlling member in a path formed in an upper stream side of the body of the valve, and in which a flow amount controlling member is movably held. In the flow amount controlling member, an orifice is formed. When the valve moves into an opening position, a high pressurized oxygen gas is flowed into a valve chamber by gas pressure, the flow amount controlling member moves and closes the path. At this time, the gas flow amount is restricted by the orifice, so that the pressurizing speed of the gas pressure at the down stream side of the orifice becomes slow and then heat generation due to the adiabatic compression is reduced.
摘要翻译：一种安装在高压气体容器中的开关阀，其具有用于将流量控制构件保持在形成在阀体的上游侧的路径中的保持部，并且流量控制构件可移动地举行。在流量控制部件中，形成有孔。当阀移动到打开位置时，高压氧气通过气体压力流入阀室，流量控制构件移动和关闭路径。此时，气体流量受到孔口的限制，使得孔口下游侧的气体压力的加压速度变慢，于是绝热压缩引起的发热减少。

摘要： A unidirectional valve, wherein the valve comprises a valve body including a frame, a valve opening through the frame, and a valve seat extending from the frame and at least partially surrounding the valve opening. The valve further includes a valve flap having a first portion attached to the frame and an adjacent second portion free to move from a first position where the second portion is in contact with at least a part of the valve seat to a second position where at least part of the second portion is spaced from the valve seat, wherein the valve flap has a contour profile. The contoured profile may be along the length of the valve flap, between the point of attachment of the flap to the frame and the flap end, or from one flap side edge to a second side edge.

摘要： A filtering face mask that comprises a mask body adapted to fit over the nose and mouth of a person; and an exhalation valve that is attached to the mask body. The exhalation valve comprises a valve seat and a flexible flap. The valve seat has an orifice through which fluid can pass and is surrounded by the seal surface. The flexible flap is operatively supported relative to the valve seat and pressed against the seal surface of the valve seat in a closed state of the exhalation valve. The flexible flap assumes in its closed state, a curved profile in a cross-sectional view thereof The curved profile comprises a curve that extends from a first point where a first portion of the flexible flap contacts the seal surface to a second point where a second portion of the flexible flap contacts the seal surface. The flexible flap is held in its closed state, at least in part, by virtue of the curved profile thereof The second portion of the flexible flap represents the only free portion of the flap and can flex so as to permit exhaled air to pass through the orifice and to provide an open state of the fluid flow valve such that the second portion of the flexible flap is out of contact with the seal surface at the second point while the first portion of the flexible flap is maintained in contact with the seal surface at the first point.
摘要翻译：一种过滤面罩，其包括适于装配在人的鼻子和嘴部上的面罩主体; 以及附接到面罩主体的呼气阀。呼气阀包括阀座和柔性挡板。阀座具有孔口，流体可以通过该孔口并被密封表面包围。柔性翼片相对于阀座可操作地支撑并且在呼气阀的关闭状态下被压靠在阀座的密封表面上。挠性翼片处于其闭合状态，呈截面视图的弯曲轮廓。弯曲轮廓包括从柔性翼片的第一部分接触密封表面的第一点延伸到第二点的第二点，其中第二点柔性翼片的一部分接触密封表面。柔性翼片至少部分地由于其弯曲轮廓而保持在其关闭状态。柔性翼片的第二部分代表翼片的唯一自由部分并且可以弯曲，以便呼出的空气通过并且提供流体流动阀的打开状态，使得柔性折片的第二部分在第二点处与密封表面脱离接触，同时柔性折片的第一部分保持与密封表面接触第一点。
