This invention relates to sealless designs of magnetorheological fluid dampers. With these sealless designs a piston rod extends above and below a piston head within a cylindrical housing and has frustoconical elastomer elements attached to and between the rod and housing to allow translation of the piston head and rod. The piston head has a coil contained radially therein that produces magnetic flux in and around the piston. The advantages of utilizing an MR fluid according to the invention include magnetic fields which are easily produced by low voltag...
Apparatus for damping motion between first and second relatively movable members, said apparatus comprising: a) a housing containing a volume of magnetorheological fluid; b) first means for attaching said housing to one of said movable members; c) a piston rod mounted for relative movement with respect to said housing; d) second means for attaching said piston rod to another one of said first and second movable members; e) a first block of elastomer interconnecting said housing and said piston rod, said block being fixedly attached to each of said housin...
