The filling device houses a compressor which is connected via a suction line comprising an inlet shut-off valve to a source of gaseous fuel, and is adapted to be connected to a gaseous-fuel container via a supply line equipped with a pressure-limiting valve and a discharge valve. The inlet valve and the discharge valve are connected to a control device which together with the pressure-limiting valve, the discharge valve and, if required, the inlet valve is disposed in a pressure-resistant casing connected to a discharge line leading away from the device. The control device is adapted to be influenced in dependence on control signals from a temperature sensor detecting the environmental temperature, a pressure sensor detecting the pressure at which the compressor is supplied, and a pressure-difference sensor disposed in front of the inlet valve and detecting the difference between the pressure in the suction line and in the casing. This device enables the supply pressure to be automatically adapted to the environmental temperature, and prevents uncontrolled escape to gaseous fuel near the filling device.
