A gas pressure regulator for a butane lighter or other gas burner is created by the interaction of two superposed washers and an underlying flat retainer disc. A compressed elastomeric washer exerts pressure on a more rigid washer having a distal textured face in contact with an opposing face of the retainer disc. Gas flows through the interstitial array between said textured face and the opposing face of the retainer disc and a net pressure differential is effected.

A gas pressure regulator for disposition in a housing member having a cavity including an end wall provided with a port comprising a pair of members of imprevious material disposed within the cavity in face to face opposed mating engagement, one of said members being firm, an elastomeric washer having a central aperture therein positioned under compression with said cavity for biasing said pair of members toward each other and presenting a flat compressive surface to said abutting members, one of said members having an aperture therethrough communicating with said port and being a thin plastic material having its mating surface textured and being flexible across its width, said textured surface containing a multitude of extremely minute communicating interstices in the order of microns to fractional microns, thereby forming between said opposed mating surfaces an interstitial array of passages offering resistance to the gas flowing across the interface between said members, said gas flow being directed radially inward from the peripheries of said members to said firm member aperture, said elastomeric washer abutting said member with an aperture the central aperture of said elastomeric washer being larger in size than the aperture in said abutting member so that the degree of compression of said elastomeric washer that is transmitted to and hence by the compressed area of said thin flexible plastic member in turn controls the amount of mating surface area of said members that is under compression thereby determining the length of the gas flow path between, the mating compressed area of said members for regulating the gas pressure drop, and means providing a passageway for gas between the members and the housing.
