    Abstract: A magnetorheological material containing a carrier fluid and an iron alloy particle component. The particle component can be either an iron-cobalt alloy or an iron-nickel alloy. The iron-cobalt alloy has an iron:cobalt ratio ranging from about 30:70 to 95:5 while the iron-nickel alloy has an iron:nickel ratio ranging from about 90:10 to 99:1. The iron alloy particle components are capable of imparting high yield stress capability to magnetorheological materials.

    Abstract: Magnetorheological (MR) fluid dampers (16) are optimized. Dimensional relationships involved in the flow of magnetic flux are related to an operational parametric ratio of magnetic flux density in the fluid to the flux density in the steel. A magnetic valve (30) is utilized to change the flow parameters of the MR fluid and, hence, the operational characteristics of the damper (16). Several embodiments depicting improved piston designs, including spool as well as toroidal configurations, are disclosed. In addition, both single (16) and twin-tube (16) housing designs are presented, along with several sealless designs. Baffle plates (50) and toroidal magnetic segments (40) interspersed with flow slots (56) are utilized to increase contact between the fluid and the magnetic coil (40).

    Abstract: An adjustable valve including a passageway, a field responsive fluid within the passageway, and fluid flow adjustment through the passageway. The valve is preferably used in a vibration damper. One damper includes a body, a piston, first and second chambers, a damping valve, a piston rod, an auxiliary chamber, a passageway interconnecting to the auxiliary chamber, a field responsive fluid, a field responsive fluid valve for controlling flow to the auxiliary chamber, and pressurization means. Preferably included is a cavity partition having field responsive fluid disposed on one side and non-field responsive fluid disposed on the other. This allows a reduction of MR fluid allowing use of lighter-weight, less-expensive, hydraulic fluids for flow through the piston's damping valve. In another aspect, the damper includes mechanical adjustment means for manually adjusting the damping level. Adjustment is accomplished by a moveable permanent magnet, moveable pole piece, moveable pole-and-magnet assembly, or magnetic shunt. Manual adjustment may include a knob, lever, or cable actuation. Alternately, magnetic flux is provided by an electromagnet. The valve and damper finds utility in any suspension system where a damper body is attached to a frame component, such as a bicycle frame, and the piston rod is attached to a suspension component, such as a bicycle's swingarm.
