Claim:
1. A supply unit for a mixer of biphasic compounds comprising: a mixing unit comprising a mixing chamber, a channel at a first end for dispensing a quantity of mixed biphasic compound, an external screw at a second end, and a piston slidably inserted inside said mixing chamber for dispensing the quantity of mixed biphasic compound through said mixing chamber; a dispensing unit comprising a drive element for said piston which is remotely controlled by a pumping means, wherein said drive element comprises a cylindrical housing inside which at least a drive piston slides in a hermetically sealed way, said drive piston and sides of the cylindrical housing defining at least a drive chamber, wherein a respective axial drive stem is integrally connected to the drive piston, and wherein said pumping means cause said drive stem to press the piston of the mixing unit for dispensing the compound, wherein the piston of the mixing chamber and the drive piston comprise independently movable pistons disposed within separate chambers, wherein said drive element comprises, on one of its ends, at least a threaded opening that connects to the external screw at the second end of said mixing unit, and on the other end at least a tang comprising an elongate tubular member defining an axial chamber having a smaller diameter than a diameter of the drive element, wherein the drive chamber communicates with the axial chamber when the drive piston is inserted within the drive chamber.
