A burner for a gas cooker or hob comprises a body (3) which defines a passage (10, 4) for the intake of primary air into the burner. A flame spreader (7) is mounted on the body (3) and defines therewith an annular gas/air mixing chamber (6). One or more orifices (7) are provided in the body (3) for connecting the air intake passage (10, 4) to the gas/air mixing chamber (6). A gas injector or needle (1) extends into the gas/air mixing chamber (6), and is spaced vertically from the inner surface of the flame spreader by a distance which causes the gas jet to impinge thereon. |
