Abstract
The invention relates to a device for supplying a gaseous fuel to an engine that comprises a gas accumulator for receiving highly pressurized gaseous fuel, a gas buffer for receiving medium pressurized gaseous fuel, a gas supply device for delivering a gaseous fuel into an engine combustion space, a first gas line that connects the gas accumulator to the gas buffer and whose gas flow can be regulated via a first valve, a second gas line that connects the gas accumulator to the gas buffer and whose gas flow can be regulated via a second valve, and a third gas line that connects the gas buffer to the gas supply device. The device is further characterized in that a compressor is arranged in the second gas line to increase a pressure of a gaseous fuel flowing from the gas accumulator to the gas buffer.
