Claim 12:
13. A dual rotating handle water conservation faucet, the faucet comprising:
a first rotating handle and a second rotating handle;
a faucet body;
a spigot in communication with the faucet body;
a first and a second flow valve assembly at least in part within the faucet body for controlling the flow of water for first and second water supply lines, each of the first and second flow valve assembly comprising:
a valve body having a water input and a water output, the water output being in fluid communication with the faucet spigot, and
a flow valve disposed in the valve body, the flow valve controlling the flow of both cold water and hot water from the spigot with a single lever by rotational movement of the lever about its longitudinal axis;
first and second ball plunger assemblies each including a ball plunger body having an opening at one end, a ball within said plunger body biased by a spring mechanism such that a portion of the ball protrudes from the opening and extends from the plunger body of the ball plunger assembly, the spring mechanism biasing the ball in a position proximate the open end of the plunger body while also permitting the ball to rotate relative to the plunger body of the ball plunger body;
first and second bonnets each having a plunger bore configured to receive the ball plunger body therein;
first and second stems housed within the first and second bonnet, respectively, each stem having an exterior surface with detent grooves formed therein, the groove at least in part encircling a portion of the stem, the grooves being sized and configured to receive a portion of the ball when positioned therein, when the ball plunger is positioned within the plunger bore, the ball is oriented to face and is maintained in position to contact the surface of the stem;
wherein when at least one of the first handle and the second handle is rotated from the off position towards the maximum on position, the ball travels along the surface of the stem surface into a first of the detent grooves and is in the first fixed position, the at least one of the first handle and the second handle remains in the first position;
wherein during rotation of the at least one of the first handle and the second handle the user feels a tactile sensation through at least one of the first hand and the second handle from the ball being seated within the first groove which provides a tactile feedback mechanism indicating to the user that that the at least one of the first handle and the second handle in the first position;
wherein when the at least one of the first handle and the second handle is further rotated toward the maximum on position, the ball exits the first detent groove and travels along the surface of the stem surface and into at least a second detent groove and is in the second fixed position;
wherein when the at least one of the first handle and the second handle is further rotated to eventually reach its maximum travel and the at least one of the first handle and the second handle cannot move any further and is at the maximum on position of the faucet where the water flow rate is at 100% for the first and second water supply line, respectively;
wherein the at least one of the first handle and the second handle continues to provide tactile feedback to the user through the at least one of the first handle and the second handle indicating the position of the as it moves from one of the grooves and into a next one of the grooves; and
wherein in addition to the tactile feedback, the at least one of the first handle and the second handle provides visual feedback to the user as it remains in the fixed position until the user chooses to move the at least one of the first handle and the second handle to another position.
