Abstract : The patent relates to a liquid propellant injector adapted to be installed into a bipropellant thrust chamber, the injector forming an orifice closed by a spring biased valve. The valve and valve seat surfaces form a frustoconical, annular opening upon opening of the valve. The liquid propellant pressure provides the opening force to overcome the valve spring bias, producing a uniform spraying pattern of the liquid propellant outwardly from the injector to combine with a solid propellant.
