Safety mixer comprises body (10) connected to the sources of two fluids (1, 2) and having a first and second inlet (11, 12), a mixing chamber (13) with two inlets (14, 15) and one outlet (16), and a system for comparing and controlling the pressure of the two fluids in ducts (21, 22) between the inlets (11, 12) and mixing chamber. Safety mixer comprises body (10) connected to the sources of two fluids (1, 2) and having a first and second inlet (11, 12), a mixing chamber (13) with two inlets (14, 15) and one outlet (16), and a system for comparing and controlling the pressure of the two fluids in ducts (21, 22) between the inlets (11, 12) and mixing chamber. The control system comprises cylinders (23, 26) containing sliding pistons (24, 27) with transverse channels (25, 28). The positions of the pistons are governed by fluid pressure in chambers (42, 46) linked to the inlet ends of the ducts. |
