<p>The device has a unique annular speed-up channel (4) connected to monopropellant feed holes (6) and with an outlet opened via an annular injection section (3). The channel and the section are defined by a fixed revolution wall located at an upstream end (91) of a wall (90) in a combustion chamber (9) of a rocket engine, and by a revolution wall integrated to a movable part (5). The part is movable in translation with respect to the fixed wall, and has a free end forming a fine point, at a side of the chamber. An elastic element (8) is formed by a calibrated spring or Belleville washers.</p> |
