Pressure tapping device and motor vehicle with pressure tapping device and pressure tapping method

摘要

There is provided a pressure sensing device (40) for a motor vehicle (10) having an internal combustion engine (12) and a fuel reservoir (13) connected to the internal combustion engine (12) by means of a fuel line (23), the fuel being stored in the fuel reservoir (13). with a storage pressure (P1) that is greater than an ambient pressure (P5), storable and thereby has pressure energy provided. According to the invention, the pressure tapping device (40) can be connected to the fuel line (23) in a fluid-conducting manner and is adapted to transfer part of the pressure energy of the fuel to a working medium (50). In addition, a motor vehicle with this Druckabgreifvorrichtung and a Druckabgreifverfahren be provided.
