Abstract
A breathing air tank and valve assembly is provided for use in a self-contained breathing apparatus. The breathing air tank and valve assembly includes a pressure vessel and a cylinder valve for connection to the pressure vessel. The cylinder valve includes a valve body having an interior, and a first fitting adapted to connect the valve body directly to the pressure vessel, thereby creating a fluid connection to the interior of the valve body. The cylinder valve includes a second fitting that is an outlet adapted to connect the valve body to a pressure reducer assembly, and a third fitting that is an inlet having a check valve. The third fitting is adapted to connect the valve body to an external source of pressurized air and thereby provide a direct air path from the external source of pressurized air through the interior of the valve body to the pressure vessel.
