    摘要： A relief valve having a crenelated exhaust ring surrounding the poppet. The crenelated exhaust ring comprises a series of alternating crenels and merlons which together define an increasing cross-sectional exhaust area circumferentially about the poppet during cracking (i.e., once the pressure in the inflatable device exceeds the cracking pressure) as the poppet rises in the relief valve in response to increased pressures and, conversely, a decreasing cross-sectional exhaust area about the poppet during closing as the poppet lowers to its re-seated, sealed position. The design of the crenels in the form of a larger upper cross-sectional area to a smaller lower cross-sectional opening, advantageously achieves a reseating pressure that is substantially equal to or slightly less than the cracking pressure while minimizing possible oscillations during re-seating of the poppet. The crenelated exhaust ring surrounding the poppet advantageously results in a relief valve having a higher flow rate at a given back pressure than would be achieved without the crenelated exhaust ring surrounding the poppet.

    摘要： A valve (10), which includes a stem (32) having a slit (52) at an end thereof. The valve stem (32) is located in a valve body (12) and is deformable. When a tip (56) of an instrument (22) is engaged with a slit (52) in the stem (32), the stem (32) shifts in the body (12), top portion folds inward, the slit (52) seals against the instrument (22) and allows liquid to flow through the stem (32), to or from the instrument (22). All components have circular cross sectional geometry.

    摘要： A free floating check valve (10) includes a seal disc (12) having an integral truncated torroidal shaped portion (16). The torroidal shaped portion (16) provides structural rigidity to the seal disc (12) to minimize deflection of the disc under higher differential pressures. The torroidal shaped portion (16) of the disc (12) cooperates with finger-shaped projections (24) inside the valve body (22) to limit lateral displacement of the disc (12) relative to the axial flow of the fluid. The torroidal shaped portion (16) and the flat portion (14) of the disc (12) form a cup shape that creates a hydrodynamic force that assists in moving the disc (12) to an opened or closed position. The seal disc (12) is made of an elastomeric material that is coated with Parylene.

    摘要： A manual inflator having a status indicator that indicates whether a fully-charged, unspent gas cylinder has been installed on the inflator. The status indicator comprises a single point indicator having an indicator window that displays the color green when the automatic inflator is fully operational or the color red when the inflator is at least partially inoperable automatically due to the removal of the gas cylinder or due to the firing of the inflator resulting in a spent gas cylinder.
