Abstract
The first stage regulator of a two-stage underwater breathing apparatus utilizes an imperforate force transfer mechanism to automatically increase the rate at which breathing air is delivered from a high pressure supply to the second stage regulator as the diver descends in the water. The first stage regulator is sealed from the ambient by the imperforate force transfer mechanism which increases the resistance of the regulator to icing and corrosion and prevents particulates entrained in the ambient water from entering the regulator mechanism and interfering with its operation.
