Abstract
An improvement in a pressure regulator including the usual valve body, seat, poppet, adjustable spring having a bottom plate for co-acting with the low pressure diaphragm member. The improvement comprises an improved regulator in which the poppet includes a centering extension shaft extending to the low pressure side of the valve seat and a larger diameter shaft in communication with the high pressure inlet chamber and having the valve seat include centering upper protrusion that closely engages the centering extension shaft of the poppet with at least three and no more than six slots disposed substantially uniform thereabout such that gas can flow about the valve poppet centering extension shaft through the valves without inducing destructive and noisy vibration when gas flow is called for by the regulator.
