The invention provides a fuel supply system for a gas generator having a minimum of moving-part components and avoids highly-pressurized containers. The system comprises a pressurizable fuel reservoir (1) connected to both the inlet and outlet of a combustion chamber via flow control means (1,16) the arrangement being such that fuel flows to the combustion chamber and other areas of use when pressure in the fuel reservoir (1) is greater than that in the combustion chamber and gas flows to the fuel reservoir (1) to pressurize the latter when the pressure therein is less than that of the combustion chamber, the respective flow control means (11,16) operating in sequence such that the system operates in a cyclical and self-generating manner. The invention is particularly applicable to gas generators forming part of rocket motors.
