Abstract
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.
