Claim Text:
1. A water flow control assembly for a single lever faucet, the assembly comprising: a faucet valve coupler adapted to operatively connect a handle of a single lever faucet to a valve stem of a valve assembly of the single lever faucet and to engage the valve assembly of the single lever faucet, the faucet valve coupler having an actuator element and a handle actuator wherein the actuator element supports the handle actuator wherein the faucet valve coupler provides a biasing resistance to handle movement as the handle is oriented in a position other than a neutral handle position; a cam mechanism having a valve stem portion and a handle portion, the cam mechanism being operatively connected to the valve stem of the valve assembly wherein the cam mechanism engages the valve stem to move the valve stem to a predefined open position in response to activation of the handle of the single lever faucet by a user when the handle is moved from the neutral handle position to a water on position wherein the predefined open position provides water flow that is less than a full open water flow, wherein the handle automatically returns to a neutral handle position with the water flowing after engagement of the handle by the user to any water on position followed by release of the handle by the user; wherein the handle automatically returns to the neutral handle position with no water flowing after engagement of the handle by the user to the water off position followed by release of the handle by the user; and wherein the handle automatically returns to the neutral handle position with some water flowing after engagement of the handle by the user to a position less than fully off, followed by release of the handle by the user.
