摘要： A controllable brake (20) including a rotor (28) supported by a shaft (30) which is rotatably supported by bushings (42) received in housing (22). A coil assembly (48) creates a magnetic field within a pole piece (32), which is preferably manufactured from a powdered metal material, which preferably has a density of between about 6.8 and 7.0 gm/cm. A magnetically-soft medium is contained within first and second gaps (86, 88) located between pole piece (32) and rotor (28). In one aspect, a magnetic saturation zone (25) reduces the propensity of magnetizing the shaft (30). In another, the pole halves (24, 26) are received in radially-spaced pole pockets (37) formed in the housing (22) and include an axial bias spring (70) to ensure intimate contact. In another aspect, a lip projection (76) traps fluid (23) between the lip projection (76) and shaft (30) and minimizes fluid exposure to the shaft seal (44). In another aspect, cooling fins (55) or a projection (53) restrains rotation of the housing (22). In another aspect, a spring (46) centers the rotor (28) relative to the housing (22).

In one aspect, a one-way check valve (34) is operative with a passive passageway (36) which is arranged in parallel relationship to the controllable passageway (42) provides "asymmetric" damping across the controllable valve (18) creating higher pressure differentials in a first direction and a lower in a second direction without "rapidly switching" the current to the coil (46). In another aspect, "asymmetric" damping is provided by a "changeable gap" formed by a moveable wall portion of the controllable passageway (42). In a third aspect, a first controllable passageway provides controllable flow in a first direction and a second controllable passageway provides controllable flow in a second direction, thereby provide "asymmetry." In a fourth aspect, "asymmetry" is provides by a "variable magnetic short" which changes magnetic circuit reluctance dependent on flow direction.

摘要： An adjustable valve including a passageway, a field responsive fluid within the passageway, and flow adjustment of the fluid through the passageway. In another aspect, the valve is in a vibration damper. In yet another aspect, the 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 device for manually adjusting a 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.

摘要： A controllable vibration apparatus having an electrical connection to a controllable valve made through a single-strand electrical conductor. In one embodiment, the piston and rod are preferably used as the source of ground or return electrical path. An axially compressed sealing element provides radial sealing against the conductor. An accumulator including a flexible diaphragm provides separation of fluid and accumulator chambers. In magnetorheological (MR) fluid dampers, a special sealing system including a relationship between piston rod surface finish and particle size is provided. A surface treated metal bushing is used with a lip seal to prevent escape of fluid and support side loads. The controllable valve can be formed from top and bottom pole pieces spaced from an outer ring to define a passageway. The pole and ring are preferably secured together by non-magnetic bridging elements. Preferably, the coil assembly is configured with integral axially-extending pins for ease of connection. Push-on connectors preferably make the connection between the conductor and pins. In a two single-strand conductor version, one single-strand carries the incoming current and the other the outgoing current.
