Automatic, In-line, Air Supply Cutoff Valve

A valve is described which eliminates hazards of a "whipping" air line, encountered when an air line breaks, or a nozzle snaps off.

This valve is shown spliced in at point of connection of the solid, rigid air supply line, and the flexible air hose being used. Its construction is such that a rapid release of air pressure through it (such as happens if an air hose ruptures) causes the ball spring inside the unit to slide forward, which shuts off the main air supply to the hose. This action reverses when the air supply balances on both sides of the valve, after the hose is repaired or replaced. A built-in delay action insures that no hazard remains after fix. Pressure is allowed to build back up to operational limits. This unit can be used on any air supply up to 500 PSI and is adjustable to shut-off at any range. Once it is adjusted, a locking device will not allow the adjustment to slip. The unit can be fabricated from standard hardware components. Disclosesd anonymously.
