  • Valve apparatus for selectively dispensing liquid from a plurality of sources
    Patent number: 8561842
    Abstract: A valve apparatus includes a valve body having a first inlet, a second inlet, an outlet, and a passageway in communication with the inlets and outlet. A valve member disposed within the passageway inhibits communication between the first inlet and the second inlet and, in a first position, the second inlet and the outlet. The valve body includes a float chamber communicating with the first inlet and the outlet. A float member disposed within the float chamber is buoyant and is operatively engageable with the valve member. The float member is displaceable upwards by liquid in the chamber to enable communication between the first inlet and the outlet. When liquid from the first inlet is depleted, the float member lowers to seal the first inlet from the outlet. The valve member moves to a second position thereby to enable the second inlet to be in communication with the outlet for dispensing liquid from the second source.
