Tap allowing the adjustment of the flow rate of two fluids and of the richness of their mixture, in particular for a welding blowtorch, formed by a body R provided, for each fluid, between an inlet nozzle 1, 2 and an outlet nozzle 3, 4, with a circuit comprising a valve for adjusting its flow rate, the positioning of these two valves being controlled by a single-control lever M2 and by a richness lever M1. The two valves are positioned, for adjusting the flow rate, by the translational movement of two cores N1, N2 simultaneously and synchronously driven by the single-control lever M2 inside two sealed symmetrical chambers C1, C2 forming part of the circuit for each fluid, a stop 25 for adjusting the richness further being provided to ensure the displacement of one of the cores N1 only by the richness lever. <IMAGE>
