ABSTRACT:
A pressure stabilizer for mediating changes in pressure within a pipeline is provided. The pressure stabilizer incorporates a plurality of perforations about a central pipeline and a circumferential enclosure about the perforations. This structure allows excess fluid to flow from the central pipeline into the space provided between the central pipeline and the circumferential enclosure. As the pressure increases within the overflow space, the medium applies a pressure to an elastomeric membrane, which in turn transfers the pressure to a plurality of dampening materials. The elastomeric membrane can be filled with a porous material providing a smoother transition within the pressure dampening process. The elastomeric membrane and respective dampening materials can be placed within the circumferential enclosure assembled about the central pipeline or utilized with a pressure-stabilizing chamber.
