Abstract
The invention relates to a device (10) for supplying a fuel consumer (1) of a vehicle (20) with a gaseous fuel. The device (10) comprises multiple pressure accumulators(2) for storing and providing pressurised fuel, as well as a discharge device (3), which fluidically connects the multiple pressure accumulators (2) with the fuel consumer (1). In order to advantageously allow for a utilisation of a temperature change occurring during a fuel discharge, preferably a discharge cold temperature released during the discharge of fuel, according to the invention, the discharge device (3) is thermally coupled to a coolant circuit (4) of the vehicle (20). The invention also relates to a vehicle (20) comprising a device (10) of this type.
Claims18
An apparatus for supplying a fuel consumer of a vehicle with gaseous fuel, comprising:
- a) a plurality of pressure accumulators for storing and providing pressurized fuel;
- and
- b) an extraction device which fluidically connects the plurality of pressure accumulators to the fuel consumer;
- wherein the extraction device is thermally coupled to a cooling circuit of the vehicle;
- and
- wherein the extraction device comprises the following components:
- b1) a valve arrangement by means of which extraction of fuel from each of the plurality of fuel accumulators can be controlled individually,
- b2) a valve control device which is designed
- to define a pressure accumulator subset which indicates from which of the plurality of pressure accumulators fuel is intended to be extracted, and
- to activate the valve arrangement depending on the defined pressure accumulator subset in such a manner that only fuel from the defined pressure accumulator subset is supplied to the fuel consumer.
