Abstract
A valve assembly for a faucet is operated by an actuation lever(s) normally positioned to be engaged by a container, for example, into which water is to be discharged from the faucet. For normal operation the lever(s) is moved in a self-return range of about 10 to 50 degrees. The lever(s) can also be swung further to a fully-on position so that the faucet can function in the normal manner by its valve system. The lever(s) operate a cam which acts on a cam follower presented by a valve stem. Responsive axial movement of the valve stem in opposition to spring pressure opens a valve.
