Patent ID: 7997393

Claim:
A magnetorheological (MR) rod guide assembly comprising: a) a monolithic, nonporous MR-rod-guide-assembly housing having a central longitudinal axis and including a through bore coaxially aligned with the longitudinal axis; b) annular first and second seals disposed in the through bore, adapted to sealingly contact an MR piston rod, and longitudinally spaced apart defining an inter-seal portion of the through bore, wherein the first seal is attached to the housing; c) an annular, nonporous rod guide disposed in the inter-seal portion of the through bore and attached to the housing, wherein the second seal is self-attached to the rod guide; d) a split bearing disposed within and attached to the rod guide and adapted to contact and slidingly receive the MR piston rod; and e) a non-annular, cylindrical, porous filter plug which is not coaxially aligned with the longitudinal axis, which is disposed in the housing radially outward of the rod guide, which has a longitudinal first end in a fluid communication with the through bore longitudinally outside the inter-seal bore portion, and which has a longitudinal second end in fluid communication with the through bore longitudinally within the inter-seal bore portion.
