Tap for dispensing either a first or a second liquid

A tap adapted for dispensing a first liquid and/or a second liquid, the tap comprising:

• a first inlet and a second inlet;
• a first outlet and a second outlet
• a handle-adapted to rotate around a centre point-so as to be placed alternatively in:
• a first open position corresponding to a rotation of the handle of a first angle with respect to a vertical reference axis-passing through said centre point, or in;
• a closed position corresponding to a rotation of the handle of a second angle with respect to said reference axis, or in;
• a second open position corresponding to a rotation of the handle of a third angle with respect to said reference axis,
• wherein said first liquid flows through the first inlet and the first outlet when the handle is at its first open position, wherein said second liquid flows through the second inlet and second outlet when the handle is at is second open position and wherein both first and second liquids are prevented from flowing when the handle is at its closed position,
• and wherein the tap comprises a distribution unit, said distribution unit being arranged so as to allow said handle to spontaneously reach said closed position in absence of external action,
• wherein said distribution unit comprises a first piston and a second piston, the first piston being able to move between a first flowing position liberating the first outlet allowing the first liquid to flow out of the first outlet when the handle is in the first open position, and a first hermetic position obstructing the first outlet preventing the first liquid to flow out of the first outlet when the handle is in the closed or second open position, and the second piston being able to move between a second flowing position liberating the second outlet allowing the second liquid to flow out of the second outlet when the handle is in the second open position, and a second hermetic position obstructing the second outlet preventing the second liquid to flow out of the second outlet when the handle is in the closed or first open position,
• wherein said first and/or second piston are configured so that, when the handle is the closed position, the pressure applied by the first liquid on a first upper surface of the first piston compensates the pressure applied by the first liquid on a first lower surface of the first piston, and so that the pressure applied by the second liquid on a second upper surface of the second piston compensates the pressure applied by the second liquid on a second lower surface of the second piston.
