An injector nozzle for a heating oil burner consists of a nozzle tip (1) with an orifice (2), a rotary element (3) which turns on the inside of the nozzle tip, and a filter (4) which is situated behind the rotary element and is fixed to the body of the nozzle tip. The filter is made from a fritted material which fills the inside of the nozzle at least as far as the rear end of the rotary element. It can be enclosed by a sleeve open at one end, which can also be made from a fritted material, such as a metal, ceramic, plastics or glass.
