ABSTRACT:
A faucet valve comprised of a valve body having a valve seat onto which is adapted to movably and freely rest a disc-shaped valve plug. An operant shaft having a central cam surface is journalled within the valve body, being arranged with the cam surface lying adjacent to the valve plug so that rotating or sliding the shaft causes the plug to tip off the valve seat. The plug is held in closed position solely by upstream pressure. A novel check valve is also disclosed for replacement of the standard washer in a faucet and for use with a "speedway" connection according to another embodiment. The faucet valve is adapted to be fixed to the spout of a tap assembly having hot and cold water, in combination with the check valve, the latter preventing backflow between the two faucet conduits in the event of a pressure differential. The faucet valve may be used independently as may the check valves. In combination, the faucet valve and check valves eliminate the need to adjust the faucets for a desired water temperature for each use. The faucet valve, when mounted on the common spout of the two faucets and being easily accessible and actuated, serves to eliminate water waste. In another embodiment, the faucet valve is a flow directional valve used, for instance, to feed water to a water treatment apparatus when shutting off the spout.
