Abstract

The injector (11) has a tricoaxial type injection element (14) that is installed between an upstream plate (12) and a downstream plate (13), and a space (65) delimiting the upstream plate and the downstream plate. An annular median coaxial pipe (21) is defined in the injection element for a propellant. An inner coaxial pipe (23) and an outer coaxial pipe (24) are fed in parallel for another propellant. The injection element is equipped with two independent and calibrated holes (41, 61).
