Abstract
The device comprises, at the outlet of the combustion chamber 3, a movable assembly comprising a hollow closure member 26 constituting a needle 27, a thermal shield 22 and an annular piston 14. This closure member acts as a piston under the effect of the pressure of the gases and drives the annular piston so as to expel a hydraulic fluid from a jack chamber 33 having an adjustable outlet 34. The closure member 26 defines a chamber 28 for calming the gases.
