FIELD: machine engineering.

SUBSTANCE: injector with a screw conical swirler contains a body and coaxially arranged and rigidly connected union with an inlet cylindrical hole which is connected to the diffuser made axisymmetrical in the body, on the cut of which there is a perforated disc. A nozzle with at least three projections centering it in axial cylindrical chamber is located in lower part of body.
