ABSTRACT:
A magnetorheological (MR) rod guide assembly includes a nonporous MR-rod-guide-assembly housing, annular first and second seals, and a non-annular, porous filter plug. The housing has a through bore. The first and second seals are positioned in the through bore, are adapted to sealingly contact an MR piston rod, and are longitudinally spaced apart defining an inter-seal portion of the through bore. The filter plug is positioned in the housing, has a longitudinal first end in fluid communication with the through bore longitudinally outside the inter-seal bore portion, and has a longitudinal second end in fluid communication with the through bore longitudinally within the inter-seal bore portion.
