ABSTRACT:
An underwater air valve assembly which is to be connected to an air inflatable vest worn by a diver. The air valve assembly is located within a housing, which in turn, has a depth gauge and a pressure gauge mounted thereon. The housing is connected through a flexible hose to the air inflatable vest. A separate conduit extending from the pressurized air tank worn by the diver is located within the hose. The conduit is connected through a connecting conduit to a manually operated first valve, which when operated, will cause conducting of pressurized air from the conduit into the hose and hence into the inflatable vest. A second manually operated valve is mounted within the housing and when moved to the open position causes conducting of air from the hose to the ambient. A second valve assembly can also be utilized in conjunction with an oral inflation passage for the conducting of pressurized air orally into the hose and hence into the inflatable vest.
