The invention concerns a device (1) for a turbomachine chamber injector, characterised in that it comprises: a conduit (2) having at least: a first opening (3), and a second opening (4), a blocking system (5) for blocking the conduit, making it possible to regulate the passage of fluids into the conduit (2), the blocking system (5) being configured to: allow fuel to flow from the first opening (3) to the second opening (4) only from a first pressure (P1) of said fuel, for the passage of a supply of fuel, and allow air to flow from the second opening (4) to the first opening (3) only from a second pressure (P2) of said air, for the passage of purge air, the second pressure being greater than the first pressure. |
