Patent number: 8640729Abstract: An automatic shut-off valve shuts off fluid flow in the event of abnormal amounts of fluid flow. A rotor inside the valve turns when fluid flows through the valve. The rotor causes a pneumatic pump to operate and cause increased air pressure. The increased air pressure causes a shut-off piston to move to a closed position when a predetermined air pressure is achieved. The shut-off valve also includes an adjustable bleeder needle to slowly bleed off air pressure when the fluid flow stops and thereby resets the valve. A detent is provided for holding the shut-off piston in the open position. A detent spring and compression bolt are provided for adjusting force on the detent. The shut-off valve is manually closed using a trip arm connected to the detent. The shut-off piston is reset by actuating a reset plunger that moves the piston back to the open position.Type: GrantFiled: December 15, 2011Date of Patent: February 4, 2014Inventor: Brian Dana
