A respiratory mask and service module combination for pressure breathing. The respiratory mask has a hardshell member that extends along the contour of the face toward the peripheral edge of the mask and has a central portion forming a canopy. An inhalation/exhalation valve assembly having two breathing conduits and integrally formed so as to provide communication between the conduits. The assembly mounts externally to the mask such that the valves are capable of being sealed along the outer surface of the respiratory mask. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to limit the scope or meaning of the claims. 37 C.F.R. 1.72(b).
