  • Magnetorheological (MR) piston ring and MR damper having same
    Patent number: 8490762
    Abstract: A magnetorheological (MR) piston ring includes an MR-piston-ring body disposable within a cylinder of an MR damper along a central longitudinal axis. The MR-piston-ring body has a radially inner surface defining a boundary of a longitudinally-extending MR passageway. The MR-piston-ring body includes a surface portion which is slidingly engagable with the cylinder and which has first and second longitudinal ends. The surface portion includes at least one surface groove each defining a secondary MR passageway and extending between the first and the second longitudinal ends. The surface groove is substantially straight and tilted with respect to a line drawn on the surface portion parallel to the central longitudinal axis. An MR damper including the MR piston ring is also described.

  • Magnetorheological (MR) piston ring with lubricating grooves
    Patent number: 8141689
    Abstract: A magnetorheological (MR) piston ring includes an MR-piston-ring body disposable within a cylinder of an MR damper. The MR-piston-ring body has a radially inner surface defining a boundary of a longitudinally-extending MR passageway. The MR-piston-ring body includes a surface portion which is slidingly engagable with the cylinder and which has first and second longitudinal ends. The surface portion includes at least one surface groove each defining a secondary MR passageway and extending from the first to the second longitudinal end or each defining an MR cavity extending from one of the first and second longitudinal ends toward, but not to, the other of the first and second longitudinal ends. An MR damper including the MR piston ring is also described.
