CONTROLLABLE MAGNETO-RHEOLOGICAL FLUID DAMPER

摘要

A damper includes a housing, a piston, and a magneto-rheological (MR) fluid. The piston (6) is movably disposed within the housing (3) such that the piston divides an interior of the housing into first and second cavities and a passage defined in the piston couples the first and second cavities. The passage includes at least a disk shape space within the piston defined between by two substantially parallel surfaces. The MR fluid damps motion of the piston by aflow of MR fluid through the passage, and a magnet (10) produces a magnetic field within at least the disk shape space of the passage.
