Vehicle-pressure tank for receiving fluid i.e. hydrogen, under normal temperature or in sub-zero state, has valve device controlled under conditions by vehicle user such that minimum pressure is reached, so that removal of fluid is allowed

摘要

The tank has an opening provided in a valve device that closes on falling below predetermined minimum pressure in a tank so as to avoid a pressure drop in the tank. A valve device is controlled under specific conditions by a vehicle user such that minimum pressure is reached, so that removal of fluid is allowed when falling below predetermined minimum pressure. The valve device is activated after entering an authorization code to an electronic control unit, so that the valve device is addressed.
