Abstract

1277220 Electromagnetic fuel injectors SOC DES PROCEDES MODERNES D'INJECTION 1 Aug 1969 [28 Aug 1968] 38689/69 Heading F1B In a fuel injector having an electromagneticallyoperated valve 4 which is opened to allow fuel to flow from a space 38 to a return line 23 and permit the injection needle valve 8 to open, the injection valve biasing piston 28 is arranged between the space 38 and a space 30 under constant pressure e. g. the substantially atmospheric pressure in the return line. The space 38 is connected to the fuel supply line 13, connected to a supply pump, through a calibrated constriction 37 and by arranging the cross-section controlled by the valve 4 to be larger or smaller than the constriction the rate of injection valve opening and closing can be varied. The biasing piston (40), Fig. 2 (not shown), may abut the injection needle valve 8 directly or through a spring biased piston (51), Fig. 3 (not shown), contained by the biasing piston.
