Tap allowing the adjustment of the flow rate of two fluids and of the richness of their mixture, in particular for a welding and cutting blowtorch, formed by a body R provided with inlet nozzles 1, 2 and outlet nozzles 3, 4 for the two fluids which open into a space of revolution containing, on the circuits of the two fluids between their inlet and their outlet, two means for adjusting the flow rate of each of them and for adjusting the richness controlled by a single-control lever M2 and by a richness lever M1. The means for adjusting the flow rate and the richness are carried by the interacting faces of discs 9, 10, 11 superposed in the space of revolution, interacting faces whose relative angular positioning is ensured, for the two adjustment means, by the single-control lever M2, and for one of them alone, by the richness lever M1. <IMAGE>
