ABSTRACT:
The present invention relates to a breath controlled air inlet valve for controlling a flow of air supplied to a wearer of a facemask, the valve permitting the flow of air when a wearer breathes in and restricting the flow of air when the wearer breathes out. The valve includes an inlet, an outlet, one or more pivotable shutters, and a shutter articulating mechanism for articulating the one or more shutters between an open state and a closed state. The shutter articulation mechanism actuates in response to the respiration of the wearer. The valve also enables a positive pressure to be maintained within the facemask by permitting an amount of air to flow around the one or more shutters when the one or more shutters are in the closed state.
