Abstract
A magnetorheological (MR) piston assembly () includes an MR piston () and a rod (). The MR piston () includes a central longitudinal axis (), first and second longitudinal ends (and), an MR passageway (), a main electric coil (), and a valve (). The MR passageway () extends from the first longitudinal end () to the second longitudinal end (). The main electric coil () is disposed to magnetically energize the MR passageway (). The valve () is operatively connected to the MR passageway (). The valve () has a first state when electrically activated which is less restrictive of the MR passageway () and has a second state when not electrically activated which is more restrictive of the MR passageway (). The rod () is attached to the MR piston (). A more detailed MR piston () and an MR damper system () are also described.
