摘要： A valve assembly (100) including a mask (106) end (104) and a supply end (102) is provided. The valve assembly (100) includes a housing assembly (120), an inhale valve (160), and an exhale valve (180). The housing assembly (120) defines a first air passageway (112) configured for inhalation (108) and a second air passageway (114) configured for exhalation (110). At least a portion of the second air passageway (114) is disposed peripherally around the first air passageway (112). The inhale valve (160) 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 (180) 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 mask 10 for breathing apparatus incorporates an oronasal mask 40, that is at least partially translucent and is preferably transparent, and a light source to illuminate it. The light source may be one or more LEDs which may be carried on a plug that is removably connectable to a port formed in the mask. Also disclosed is a mask in which the exhalation valve (23, figure 2; 22, figure 3a) operates at a higher pressure when a pressurised air supply is attached to the mask. A spring 27 is normally prevented from opposing operation of the exhalation valve by the tip 31 of lever arm 30. However, connecting a pressurised air supply brings an adaptor to bear on a cam surface 30a of the lever arm and releases the biasing spring to bear on the exhalation valve.

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.
