Abstract
A method of manufacturing a diaphragm assembly for a fluid pressure regulator includes the steps of providing a diaphragm head unit having a first side and a spring seat, providing a fabric layer, providing an elastomer layer, applying an adhesive to the first side of the diaphragm head unit, placing the fabric layer between the elastomer layer and the first side of the diaphragm heat unit to form a sandwich, and applying heat and pressure to the sandwich. In a fluid pressure regulator including a disk for regulating the flow of fluid through an orifice, a valve stem attached to the disk, a valve stem guide surrounding a portion of the stem, a valve lever coupled to the valve stem, a pivot pin pivotally connecting the valve lever to a lower casing, a lever retainer adjacent the pivot pin for holding the pivot pin in place, and a boost tube adjacent the orifice, the boost tube, stem guide, and lever retainer comprise a one-piece boost tube unit.
