Combustion chamber comprising two types of injectors in which the sealing members have a different opening threshold

A combustion chamber for a turbomachine, comprising:

• at least one spark plug,
• at least one fuel injector of a first type, located facing the spark plug,
• at least one fuel injector of a second type, farther away from the spark plug than the injector of the first type,
• each fuel injector comprising:
• an opening for intake of fuel,
• a first fuel outlet,
• a mobile sealing member configured to be mobile between an open position in which it lets fuel pass through in the direction of the first outlet and a closed position in which it plugs the intake opening, wherein the mobile sealing member is configured to open when the fuel pressure applied to the mobile sealing member exceeds an opening threshold of the mobile sealing member, and
• a first elastic return means configured to stress the mobile sealing member towards its closed position, and
• wherein the opening threshold of the mobile sealing member of the injector of the first type, called first opening threshold, is strictly less than the opening threshold of the mobile sealing member of the injector of the second type, called second opening threshold.
