Civilian and military respirators must, for the most part, be functionally similar. However, the environments in which military respirators must operate, impose additional and more severe requirements on their mechanical design. The functional design requirements for military-type respirators are discussed in this report. Two fluid amplifier circuits, one for a pressure-cycled and the second for a volume cycled respirator, are described and discussed. The results of the initial in vitro tests on the first prototypes suggest that they can satisfy the predicated design requirements.
