Abstract:
A method for manufacturing an energy attenuation restrictor device containing a polymeric tuning cable and a polymeric fitting member, wherein said restrictor device is used in an energy attenuation apparatus for the attenuation of pressure pulsations in the liquid employed in a power steering system in a vehicle, comprising:selecting a first organic polymeric material for use in constructing said tuning cable, molding said tuning cable from said first organic polymeric material in an injection molding machine so that the tuning cable comprises a tubular wall structure having an inner and an outer surface; selecting a second organic polymeric material for use in constructing said fitting member, said first and second polymeric materials having characteristics such that the tuning cable and fitting member fabricated therefrom, respectively, form said device that is compatible with an environment in which it is employed; and molding said fitting member from said second polymeric material in an injection molding machine so that the fitting member comprises a tubular wall structure having an inner surface and an outer surface, wherein said fitting member is disposed on one end of said tuning cable such that an inner surface of said fitting member is adjacent to or continuous with said outer surface of said tuning cable.
