Reservoir of gaseous fuel in liquid phase

A reservoir for gaseous fuel in a liquid phase, said reservoir comprising:

• an elongate cylindrical wall;
• a lower end wall abutting the cylindrical wall and provided with a filling orifice;
• an upper end wall abutting the cylindrical wall and provided with a draw-off orifice equipped with a draw-off member and with a pressure reducer;
• an internal volume defined by the cylindrical wall and the end walls;
• an absorbent medium occupying less than all of the internal volume;
• and
• a chamber defined by an unoccupied portion of the internal volume between the absorbent medium and the upper end wall,
• wherein the chamber has a volume that is at least equal to a volume of the fuel in the liquid phase not absorbed by the absorbent medium when the reservoir is upside down;
• wherein the draw-off orifice is equipped with a draw-off tube of fine bore positioned upstream of the pressure reducer and housed axially in the chamber, and wherein the draw-off tube is of sufficient length that an innermost end of the draw-off tube is not below a level of the fuel in the liquid phase which may be present in the chamber when the reservoir is upside down.
