Abstract:
1. A faucet comprising: a body with a first fluid inlet, a second fluid inlet, an outlet and a neck portion with a central cavity defined therein; a mixing chamber positioned within the central cavity of the neck portion of the body which is rotatable about a longitudinal axis, the mixing chamber comprising an elongated cylindrical body with a first inlet port and a second inlet port positioned at a bottom portion thereof and an outlet port positioned on a side wall of the elongated cylindrical body at a top portion thereof, the first inlet port and the second inlet port being in fluid communication with the first and second fluid inlets of the body, respectively, and the outlet port being in fluid communication with the outlet of the body; a timing mechanism coupled to the mixing chamber, wherein the timing mechanism includes a timing cartridge positioned within and removable from the top of a central cavity of the mixing camber; wherein the timing cartridge has a shutoff valve positioned above the mixing chamber inlet ports but below the mixing chamber outlet port and wherein the shutoff valve controls the flow of fluid through the faucet; and an operating handle coupled to the timing mechanism that is movable along the longitudinal axis from a closed position to an open position, wherein the operating handle is rotated about the longitudinal axis to determine a fluid temperature by changing an area of the first inlet port relative to the second inlet port of the mixing chamber and pressed down along the longitudinal axis to the open position, thereby causing fluid flow through the outlet of the body and, upon release of the operating handle, the timing mechanism causes the operating handle to return to the closed position after a predetermined period of time, thereby stopping fluid flow through the outlet of the body.
