ABSTRACT:
A hose coupling for use with a faucet, including an upright rod which is adapted for vertical motion in response to the water pressure in the hose. When the water pressure in the hose is normal, the upright rod moves to the upper limit of its range of travel, and slightly projects upward beyond a valve seat, pushing up a steel ball valve, and allowing the water to be discharged from the hose tip. If the water pressure in the hose increases abnormally, the upright rod retracts downward and allows the ball valve to fit on the valve seat.
