ABSTRACT:
A regulator first stage for underwater diving which provides an added low pressure port for connection to an automatic vest inflator. The added port permits a shorter and more direct connection between the regulator and inflator. It also provides restricted flow to the vest to prevent too rapid inflation and/or over-inflation and provide better control of the vest inflation by the diver.
