Abstract:
1. A multi-mode, fluid-control valve comprising: a main body defining an enclosed chamber having a plurality of inlet ports and an outlet port, said outlet port having an associated seat in the chamber; a revolving rotor disposed inside the chamber and connected to a selector handle located outside the chamber, the rotor configured to provide a possible passageway between each of the inlet ports and the outlet port; at least two balls positioned in the rotor and sized to lodge in the seat in the chamber such that the passageway is cut off from at least one of the inlet ports; and, a compression spring bearing against the at least two balls and adapted to maintain at least one of the balls lodged in the seat; whereby rotation of the selector handle causes the rotor and the at least two balls and the spring to revolve inside the chamber, thereby controlling the fluid flow between the plurality of inlet ports and the outlet port.
