Burner (5, 143, 158, 179, 269) for a gas burning hand tool (1), of the type comprising an elongated burner body (21, 147, 161, 183, 273), associated at opposite ends of the burner body with a gas injection zone (17, 145, 159, 181, 271) and a gas combustion zone (19, 155, 163, 185, 276), characterised in that the gas injection zone (17, 145, 159, 181, 271) comprises at least one outlet orifice (35, 171, 211, 309) terminating flush with the outside of the periphery (25, 153, 240, 270) of the burner body (21, 147, 161, 183, 273), while this periphery (25, 153, 240, 270) promotes the circulation of the gas on the outside of the burner body (21, 147, 161, 183, 273) towards the combustion zone (19, 155, 163, 185, 276).
Burner according to one of the preceding claims in which the gas injection zone (17, 145, 159, 181, 271) has a plurality of outlet orifices (35, 171, 211), each of the outlet orifices (35, 171, 211) terminating flush on the outside of the periphery (25, 153, 240, 270) of the burner body (21, 147, 161, 183, 273).
Burner according to one of the preceding claims, in which the outlet orifice (35, 171, 211, 309) terminates in a gas injection channel (45;
- 47, 197), the said channel extending (35, 171, 211, 309) parallel to the external periphery (25, 153, 240, 270) of the burner body (21, 147, 161, 183, 273) at least in the vicinity of the said orifice (35, 171, 211, 309).
Burner according to one of the preceding claims, in which the injection zone (17, 145, 159, 181, 271) has a plurality of outlet orifices (35, 171, 211) distributed around the peripheral surface.
Burner according to one of the preceding claims, in which the injection zone (181) comprises at least one at least partly annular outlet orifice (211, 309), surrounding at least partly the periphery (183) of the burner body (183).
Burner according to one of the preceding claims, in which the gas combustion zone (19, 155, 163, 185, 276) has a flame capture zone (89, 144, 161, 241, 275) situated in the vicinity of the end of the burner.
Burner according to one of the preceding claims, comprising in addition a flame lighting device (83, 157, 178, 236, 293), disposed in an internal zone (87, 91, 243) of the burner body (21, 147, 161, 183, 273).
Burner according to one of the preceding claims, in which the periphery (25) of the burner body (21) has a zone of inflection (31), between the injection zone (17) and the combustion zone (19).
Burner according to one of the preceding claims, having at least one protective flange (169) projecting outside the periphery of the burner body (161), and extending from the injection zone (159) to the vicinity of the combustion zone (163).
Gas burning hand tool comprising a burner according to one of the preceding claims.
