Quick connect pressure reducer/cylinder valve for self-contained breathing apparatus
First Claim
1. A breathing air tank and valve assembly for use in a self-contained breathing apparatus, comprising:
- a pressure vessel; and
a cylinder valve for connection to the pressure vessel, the cylinder valve including;
a valve body having an interior;
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;
a second fitting, the second fitting being an outlet adapted to connect the valve body to a pressure reducer assembly; and
a third fitting, the third fitting being an inlet having a check valve, wherein 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.

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.

11. A cylinder valve for connection to a pressure vessel, comprising:
-
a valve body having an interior; 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; a second fitting, the second fitting being an outlet adapted to connect the valve body to a first pressure reducer assembly; and a third fitting, the third fitting being an outlet and having a check valve, wherein the third fitting is adapted to connect the valve body to a second pressure reducer assembly to thereby provide an air path from the pressure vessel through the interior of the valve body to the second pressure reducer assembly. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
