Three-position valve for water supply systems

A three-position faucet for water supply systems, comprising:

• a body housing a ball arranged in a leak-tight assembly and with rotational capability for establishing positions for opening and closing the passage through the faucet between an inlet conduit and an outlet conduit, characterized in that the ball has a conduit extending from a side area to the middle area, from where there is arranged in continuation another conduit opening perpendicularly downwards, whereas another conduit of a smaller diameter opens perpendicularly from one side to the conduit, the lower conduit facing an outlet conduit defined by the body of the faucet, whereas depending on the rotation of the ball, the conduit, the conduit, or the blind portion opposite any of them can be arranged facing an inlet conduit defined by a tubular bushing coupled to the body, for establishing an open passage position, a reduced passage position, or a closed passage position, through the faucet, respectively.
