摘要： A controllable valve assembly (18) applicable in Magnetorheological (MR) fluid devices (20), such as MR mounts and MR dampers. The valve assembly (18) includes a valve body (32) having a magnetic circuit (40) contained therein which carries magnetic flux .PHI., a controllable passageway (42) within the magnetic circuit (40), a MR (magnetically controlled) fluid (44) including soft-magnetic particles in a liquid carrier contained in the controllable passageway (42), a magnetic flux generator, such as a wound wire coil (46), generating magnetic flux .PHI. which is directed through the MR fluid (44) in the controllable passageway (42) thereby generating "rheology" changes causing restriction in flow of MR fluid (44) therethrough. 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： A haptic interface system or force feedback system having a magnetically-controllable device that provides resistance forces opposing movement. The magnetically-controllable device is adapted for use with a force feedback computer system to provide force feedback sensations to the system's operator. The magnetically-controllable device contains a magnetically-controllable medium beneficially providing variable resistance forces in proportion to the strength of an applied magnetic field. The system further comprises a controller that executes an interactive program or event, a video display, and a haptic interface device (e.g. joystick, steering wheel) in operable contact with an operator for controlling inputs and responses to the interactive program. Based on the received inputs and on processing the program, the controller provides a variable output signal, corresponding to a feedback force, to control the magnetically-controllable device for providing dissipative resistance forces to oppose the movement of the haptic interface device and to provide the operator with a force feedback sensation.

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.
