1. A system for supplying gaseous fuel to a fuel consumer at a desired supply pressure from a fuel source within which fuel is stored at a storage pressure different from the supply pressure, the system comprising:
at least two variable volume chambers, and valving for connecting each of the variable volume chambers cyclically and alternately to the fuel source and the fuel consumer, the valving serving during each system operating cycle to connect a first of the variable volume chambers to the fuel consumer to supply fuel thereto at the desired supply pressure and to connect a second of the variable volume chambers to the fuel source to introduce a quantity of fuel in the second variable volume chamber at the storage pressure;
wherein the quantity of introduced fuel is no greater than the fuel mass required to fill the second variable volume chamber at a pressure that does not exceed the supply pressure, and the volume of the second variable volume chamber is changed subsequent to the introduction of the quantity of fuel therein, to change the pressure in the second variable volume chamber from the storage pressure to the supply pressure in readiness for an ensuing system operating cycle.
