ADA metering faucet mechanism

Abstract

A metering faucet includes a housing and a faucet metering cartridge positioned within the housing and having an outwardly extending faucet stem which is movable along a stem axis. There is a cartridge cap which is positioned within the housing and has a portion extending over and in contact with the cartridge stem to provide an inward force thereon. A handle is pivotally mounted to the housing on one side of the stem axis, with the handle having a portion which extends through a housing opening to contact the cartridge cap. Upon pivotal movement of the handle, an inward force is applied on the cartridge stem. The handle has a force applying area which extends a substantial distance from the pivotal mounting of the handle and terminates at the diametrical opposite side of the pivotal mounting of the handle.
