ABSTRACT:
An air supply system which communicates between the compressed air supply and the mouth of a scuba diver utilizes a sealing cup which surrounds the mouth to define a breathing/microphone chamber into which the diver can speak. In addition to this chamber into which the diver can breath, a mouthpiece on an airpipe which passes through the sealing cup can be quickly forced into the mouth for direct breathing through the mouth into the air tube, bypassing the breathing chamber defined by the sealing cup in the event this chamber becomes flooded.
