Abstract
A positive pressure demand regulator having a housing with a connection for delivering breathing gas with an outlet connected to the housing for attachment to a mask. A diaphragm is mounted in the housing and a passage connects the outlet and the diaphragm so that the diaphragm can be in fluidically connected relationship to the outlet. A main valve interconnects the breathing gas connection to the outlet for valving breathing gas to the outlet. A cam is attached to the diaphragm for lifting the diaphragm into an inoperative mode with a detent connected to the cam operated by a cam rod engaging a cam surface to lift the detent into a position for placing the detent in displaced relationship from where the diaphragm is in an operative mode, mounted in the housing on the side of the diaphragm opposite from the outlet.
