The injection nozzle comprises a nozzle body 1 with an opening 2, a rotary member 3 kept rotating inside the nozzle body 1 close to the nozzle opening 2, and a filter 4 placed upstream of the rotary member 3 and provided to be fixed to the nozzle body 1.
<??>The filter 4 is a sintered body and fills the space at least as far as the rotary member 3.
<??>The filter 4, traversed by the liquid fuel, retains the fuel for an extended time interval, which advantageously decreases the formation of air cushions in the nozzle body, and increases the reliability of the oil burner.
