Abstract:

The equipment evaluated consists of U. S. Divers Cos new two stage regulator, the Aqua-Master, and a pair of revised type 3000 psi aluminum cylinders, as specified by BUSHIPS, with straight thread O-ring sealing arrangement. The overall apparatus did not meet acceptance criteria having an unacceptably high exhalation resistance as a consequence of a new design exhaust flapper valve. Substitution of the old style upper cover-exhaust valve assembly brought the resistance characteristics within specifications. The O-ring cylinder seal is basically satisfactory but not in accordance with military standards. Numerous minor mechanical deficiencies are noted for change. Modified author abstract
