Definitions
- DESCRIPTION Fuel gas supply device for providing a fuel gas
- the invention relates to a fuel gas supply device and an internal combustion engine with such a fuel gas supply device.
- a fuel gas supply device which serves to provide a fuel gas for a consumer at a fuel gas supply point, typically has a fuel gas reservoir, which is configured to store liquid fuel gas.
- the fuel gas is in particular in the deep-cold state and thus liquefied before.
- Fuel gas supply point to be able to provide a sufficiently high supply pressure, it is either necessary to bias the fuel gas reservoir in total to a correspondingly high pressure level, or it must be a cryopump used to compress the cryogenic fuel gas.
- a biasing of the fuel gas reservoir to a high pressure is problematic for safety reasons, with a required effort to ensure adequate safety increases with increasing tank size to an unreasonable effort in very large tanks.
- Such large Brenngasreservoire must then be made very difficult and therefore expensive for reasons of strength.
