ABSTRACT:
A reinforced expandable resilient plug for a flow regulator is disclosed, and the preferred and illustrated embodiment thereof incorporates a multiply wrap, each ply being independent of the other plies and coextensive with the outer surface of the plug to provide strength. Each ply is formed of lengthwise, nonyieldable fibers, and the several fibers which form a ply are collectively joined together into a sheath of yieldable, stretchable material. Each ply is, therefore, able to stretch in a dimension enabling the plug to expand while lengthwise elongation of each fiber prevents expansion in that dimension. This assists in maintaining the shape of the inner plug.
