- at least one interface region (10);
- at least one fuel inlet opening (21);
- at least one fuel outlet opening (22);
- at least one fuel outlet portion (22);
- at least one heating chamber (3) provided with an internal region (31), cooperating with the interface region (10), so as to project from the inlet portion (21);
