Abstract
The present invention relates to an injector of tricoaxial structure comprising a body that is circularly symmetrical about an axis of symmetry, said body being provided with a plurality of injection elements having axes parallel to said axis of symmetry and passing through an injection wall fixed to said body and separating said injector from a combustion member to which it is coupled. According to the invention, each of said injection elements comprises a central injection channel fed with a second propellant and an annular injection slot surrounding said central channel and fed with a first propellant, an additional annular injection channel for the second propellant being formed by a space that exists around each injection element between its side wall and said injection wall, such that the sheet of first propellant flowing from said annular slot is engaged between the central jet and the outer sheet, each of which delivers the second propellant.
