PROBLEM TO BE SOLVED: To provide an injection system for a turbomachine combustion chamber where a defect seen in conventional arts is relieved. SOLUTION: The injection system is provided with a fuel injection nozzle for vaporizing fuel in the combustion chamber, and a mixer/deflector assembly. The assembly is provided with a primary swirler (40) and a secondary swirler (42), the swirlers are coaxially at a determined distance from each other, and the turbomachine combustion chamber is separated by a Venturi device (44) disposed coaxially with an injection nozzle. The primary swirler is firmly mounted on the injection nozzle and situated separately from the injection nozzle by a constant radial distance. The radial distance is determined such that fuel vaporized by the injection nozzle can under no circumstances collide with the primary swirler.
