Patent ID: 8747104

Claim:
A liquated gas lighter with non-adjustable flame height, of the type comprising a liquated gas reservoir, a burner provided with a chimney through which a gas flow from said liquated gas reservoir is sent outside and a gas flow rate limiting device consisting of a microporous membrane gripped between a first seating body and a second seating body, with said first and second seating bodies delimitating a passage area in said membrane; wherein: said first seating body comprises at least one through hole that comes out, on one side directly into said microporous membrane, reaching and directly intersecting said microporous membrane, and on the other side into said liquated gas reservoir, with the intersection of said through hole and said microporous membrane defining in said microporous membrane a first area coinciding with said through hole; said second seating body comprises a seating surface in contact with said microporous membrane, a groove formed in said seating surface, an outlet duct towards said chimney and at least one linking passage that connects said groove to said outlet duct, with said groove defining in said microporous membrane a second area coinciding with said groove; said first and second seating bodies are shaped so that when they are assembled one against the other gripping said microporous membrane between them, said through hole on said first seating body is facing, partially and through said microporous membrane, said groove of said second seating body, so that a part of said first area faces said groove and the other part of said first area does not face said groove, and so that said second area defines with said first area an intersection, with said passage area being thus defined by the sum of said intersections; and so that one side of said microporous membrane rests on said seating surface of the second seating body in the part of said first surface which does not face said groove, and simultaneously the opposite side of said microporous membrane rests on said first seating body along the perimeter of said first area.
