SAFETY AIR VALVE SWITCH FOR A PRESSURIZED AIR LINE
A safety air valve switch for a pressurized air line is provided. The valve may be in the form of an exterior sliding sleeve. The safety air valve switch for a pressurized air line moves between an open and a closed position. In the open position the safety air valve allows pressurized air to flow through an air line of, for example, a tire inflation hose. In the closed position the safety air valve switch prohibits the flow of air through the air line. The safety valve allows for safe venting of pressurized air when switching between the open and closed position.
1 ) A safety valve for a pressurized air line comprising:
a first unit of the pressurized air line wherein the first unit has an exterior surface and a hollow interior;
a second unit of the pressurized air line wherein the second unit has an exterior surface and a hollow interior;
a barrier located between the first unit and the second unit;
a slidable sleeve having an interior surface and an exterior surface wherein the interior surface of the slidable sleeve covers a portion of the exterior surface of the first unit and a portion of the exterior surface of the second unit;
wherein the air line contains pressurized air;
wherein the slidable sleeve moves from an open position wherein the air may flow from the first unit to the second unit to a closed position and wherein air may not flow from the first unit to the second unit; and
wherein in the open position the pressurized air exits the first unit through an opening on the first unit and enters a first hollow channel of the interior surface of the slidable sleeve and returns to the air line through an opening of the second unit while bypassing the barrier.
2 ) The safety valve for a pressurized air line of claim 1 further comprising:
a second opening channel on the interior surface of the slidable sleeve wherein the second opening channel on the interior surface of the slidable sleeve has an open first end and a closed second end and wherein air is vented out of the open first end of the second opening channel of the interior surface of the slidable sleeve when the slidable sleeve is in the closed position.
3 ) The safety valve for a pressurized air line of claim 2 further comprising:
a first o-ring located within an indented groove located between the first opening channel of the interior surface of the slidable sleeve and the second open channel of the interior surface of the slidable sleeve.
4 ) The safety valve for a pressurized air line of claim 1 wherein the safety valve is made of a non-corrosive metal.
5 ) The safety valve for a pressurized air line of claim 3 wherein the first opening channel of the interior surface of the slidable sleeve is located between the first o-ring and a second o-ring.
