1,139,845. Free-piston gas generators. SOCIETE D'ETUDES ET DE PARTICIPATIONS EAU, GAZ, ELECTRICITE ENERGIE S.A. and SOCIETE INDUSTRIELLE GENERALE DE MECHANIQUE APPLIQUEE. Dec. 7, 1966 [Dec. 14, 1965], No. 54834/66. Heading F1Q. A free-piston gas generator installation comprises an accumulation chamber 8 for fuel under pressure, an injection pump 2 operative by the free pistons of the gas generator for feeding fuel to the chamber, fuel injector means 18 for the gas generator, communication means between the accumulation chamber and the fuel injector means, valve means 13 operative by the injection pump at the end of its fuel supplying process to the accumulation chamber, to open the communication means and means for controlling the pressure in the accumulation chamber dependent upon the load on the gas generator. The means for controlling the pressure in the accumulator chamber may also control the loading pressure of the fuel injector needle 19. The means for controlling the pressure in the accumulation chamber may be controlled by the pressure of air fed to the motor cylinder of the autogenerator or by the pressure of gas delivered by the autogenerator. At the end of the delivery stroke the piston 1 of the injection pump abuts against the stem 12 of a valve 13 which is lifted against the action of a spring 14 thereby establishing a communication between the accumulator chamber 8 and the injector 18. |
