Abstract
A system for injecting a mixture of air and fuel into a turbomachine combustion chamber is disclosed. The system includes a fuel injector and a Venturi with an interior surface delimiting a premixing chamber. The Venturi includes an internal annular airflow cavity which is connected by air outlet ducts to the premixing chamber. The air outlet ducts open onto the interior surface of the Venturi so as to prevent to deposition of soot and the formation of coke on this surface.
