    • A torch comprising a first channel (210, 304) for supplying fuel gas to a flame, a second channel (208, 306) for supplying oxidising gas to the flame, and a gas flow control device (212) with a gas flow cut-off member (322, 324) combined with each channel (304, 306), a device (340) for synchronising the two cut-off members (322, 324), and a single device (346) for actuating said cut-off members (322, 324). Said torch comprises a pilot flame (218) supplied with fuel gas via a third supply channel (220, 221, 308) provided with a third gas flow cut-off member (326) combined with the third channel (308) and controlled in synchronism with the first two cut-off members (322, 324) by said synchronising device (340) actuated by said single actuating device (346). The above assembly is useful in oxyacetylene torches.
