    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： A valve assembly including a mask end and a supply end is provided. The valve assembly includes a housing assembly, an inhale valve, and an exhale valve. The housing assembly defines a first air passageway configured for inhalation and a second air passageway configured for exhalation. At least a portion of the second air passageway is disposed peripherally around the first air passageway. The inhale valve is configured to be biased to an open position when subject to a reduction in pressure due to inhalation, and to be biased to a closed position when subject to an increase in pressure proximate due to exhalation. The exhale valve is configured to be biased to a closed position when subject to a reduction in pressure due to inhalation, and to be biased to an open position when subject to an increase in pressure due to exhalation.

    摘要： A mounting assembly for a self-contained breathing apparatus (SCBA) includes a back plate defining a plurality of apertures therethrough arranged in first and second columns. The apertures in the columns are sized and spaced to receive corresponding first and second mounting straps woven therethrough that are configured to extend around webbing straps of a carrying jacket to fasten the back plate to the carrying jacket. The back plate includes a first press stud associated with the first column and a second press stud associated with the second column, which are configured to engage ends of the respective first and second mounting straps to releasably secure the mounting straps to the back plate. A tank securing strap on the back plate releasably fastens a supply tank to the back plate. A valve retaining mount on the back plate releasably secures an air supply valve for engagement with the supply tank.

    摘要： A mounting assembly for a self-contained breathing apparatus (SCBA) includes a back plate defining a plurality of apertures therein that are arranged in two columns extending down opposing side edges of the back plate. The apertures are sized and spaced to receive mounting straps that are configured to interface with webbing straps of a carrying jacket to fasten the back plate to the jacket. The mounting assembly also includes a tank securing strap with a quick release mechanism that is fastened to the back plate. The tank securing strap is configured to engage a supply tank to releasably fasten the tank to the back plate. The mounting assembly further includes a valve retaining mount disposed on the plate. The valve retaining mount is configured to releasably secure an air supply valve to the back plate for engagement with the supply tank.

    摘要： A carrying system is provided for use with breathing apparatus. The carrying system includes a backplate and a plurality of straps adapted to hold the backplate on the back of a user when the carrying system is worn. The backplate includes at least one plate of a plastics material. The at least one plate having a predetermined shape and the at least one plate being adapted to provide impact protection to a user during use by at least partially absorbing and/or dispersing impact forces, and to deform resiliency in response to external forces imposed by bending and/or twisting of a user during use and return substantially to its predetermined shape when not subjected to an external force.
