摘要： A faucet with control mechanism for passing water through the faucet or for shutting the water off, which comprises ceramic discs having mating long-wearing highly polished faces that provide a water seal when the discs are in closed position, and have openings therein which provide a water passageway when the discs are in open position for axial flow, wherein the ceramic discs themselves form the passageway or pressure vessel which contains the flow and permits the use of a side-operated handle which attaches to a controller inside the faucet which is open to the atmosphere. A lower body portion has a threaded stem with a pair of opposed flat portions for admitting a split mounting washer without having to thread the washer on the threaded stem all the way from the bottom of the stem.

摘要： A diverter valve has an IN port and first and second OUT ports which are positioned along an arcuate path. A rotor has an external control knob and a stem extending within the cavity of the valve body. Mounted on the stem, at right angles thereto, is a closure pin which extends into the bore of the hub of a mushroom-shaped closure element. The surface of the domed head of the closure element is in contact with an O-ring seal at one of the OUT ports. When the rotor is moved, the O-ring, in contact with the surface of the domed head, cams the closure element inwardly causing the element to slide on the closure pin and causing the closure pin to enter more deeply into a recess in the head of the closure element. When the closure element is in place to close-off one of the OUT ports, the other OUT port is opened and the pressure of the water flowing through the valve exerts a direct pressure on the flat annular undersurface of the head of the closure element. The lines of force of such pressure are perpendicular to the closure elements undersurface thereby maintaining the closure element in tight contact with the O-ring seal. Although not essential to the operation of the diverter valve, a light compression spring may be placed surrounding the hub of the closure element.
