1. A system for supplying a gaseous fuel, comprising:
a tank for storing fuel to be supplied; and
a rail that is fluidically connected to at least one injector device for discharging the gaseous fuel into a fuel space, wherein
a pressure store that is configured to receive the gaseous fuel and that is fluidically connectable to both the tank and the rail to buffer fuel coming from a low temperature tank and to supply it to the rail; and
a compressor arranged upstream of the pressure store to supply gaseous fuel increased in pressure to the pressure store, and
wherein the rail is fluidically connectable to a suction side of the compressor via a fluid return line to supply gaseous fuel not required in the rail to the pressure store.
