Air tank filling system |
摘要 |
A self contained braathing apparatus (SCBA) has a fill valve for filling the air tank while a user is wearing the SCBA. An SCBA conventionally has a pressure gauge or other apparatus on a hose that extends around generally to the front of the user, and this apparatus is provided with a quick disconnect valve as a tank fill valve. Such appratus must include a flow limiting orifice, and the present invention includes a check valve in parallel with the orifice so a substantial air flow can be obtained in one direction while the flow in the opposite direction is limited to the safety-mandated small flow.
