PCT No. PCT/FR94/00529 Sec. 371 Date Jan. 5, 1995 Sec. 102(e) Date Jan. 5, 1995 PCT Filed May 6, 1994 PCT Pub. No. WO94/27038 PCT Pub. Date Nov. 24, 1994The present invention relates to a parallel-sheet injector provided with a body about an axis to which there is coaxially connected at least one annular injection element comprising a central annular injection slit surrounded by two other annular injection slits. The central annular slit is fed with a second propellant which enters at the top of the injection element level with said central slit and the other annular slits are fed with a first propellant which enters at the base of the injection element, on either side of the central slit, and passes through an annular homogenization cavity from which it flows towards the annular slits surrounding the central injection slit. The invention also relates to injection elements which may be used within the scope of this injector.
