METHOD AND DEVICE FOR FEEDING LIQUEFIED GAS FUEL FOR AUTOMOBILE

摘要

PROBLEM TO BE SOLVED: To provide arts for feeding liquefied gas fuel for an automobile capable of easily situating a liquified gas service station without using gas for pressurization.

SOLUTION: A liquified gas fuel feeding device comprises a first pressure regulating means 11 to regulate a pressure in a first container 3 by heating the container 3; a pressure detecting means 5; a second pressure detecting means 33 to detect a pressure in the vicinity part of a feed port part 31 of a fuel feed line; a second pressure regulating means 45 to regulate a pressure in a second container 37 by cooling the second container 37 to which a branch line branched from the fuel feed line is coupled; a third pressure detecting means 39 to detect a pressure; and a flow passage switching means 21 to switch a flow passage into a state that a fuel feed line 23 is communicated with a branch line 25; and a control part 63. A fuel feed device heats liquefied gas fuel in the first container 3 on the basis of the first pressure regulating means 11 in accordance with a pressure in the first container 3 and a pressure in an on-vehicle LP container 29 of an automobile 27, and a difference between a pressure in the container 3 and a pressure in the on-vehicle LP container 29 of the automobile 27 is regulated to a value higher than a preset pressure difference and liquefied gas is supplied.
