Abstract
Four embodiments of fuel air injectors wherein variations in the amount of fuel discharged due to the existence of pressure variations between the injector valve and its seat in the fuel injector are minimized. This is done by provided a restricted orifice downstream of the point of fuel injection so that combustion chamber pressures are dampened from the fuel injector. In all embodiments of the invention the injector valve is a poppet valve having a configured stem portion for slideably supporting the poppet valve within the housing while permitting flow therepast. In two embodiments, the fuel is delivered to the injector above the configured portion of the poppet valve and in two embodiments the fuel is delivered below the configured portion of the poppet valve for improving responsiveness.
