Valve for fuel supply system

A valve (142) for a fuel supply system (100) of an internal combustion engine (102) is disclosed. The valve (142) may include a valve housing (150) that defines a channel (164) therethrough. The channel (164) may be in fluid communication with an inert gas supply line (110) at a first end (152) of the valve housing (150). The valve housing (150) may include a first flange (158) disposed at a second end (156) thereof. A valve body (174) may be disposed within the channel (164) of the valve housing (150) and may allow the channel (164) of the valve housing (150) to communicate with an inner bore (166) of a double-walled connecting element (114). A second flange (190) may be disposed adjacent to the first flange (158). The first flange (158) and the second flange (190) may be coupled to the double-walled connecting element (114). The second flange (190) may include a passage (202) therethrough in fluid communication with a detection space (172) of the double-walled connecting element (114). The first flange (158) and the second flange (190) may define a detection gap (208) therebetween. The detection gap (208) may be fluidly communicated with the passage (202) of the second flange (190).
