Abstract
A sealless magnetorheological fluid device is disclosed in the form of an engine mount which comprises a baffle plate (58) and a solenoid type coil (40) wrapped within a housing (20). The baffle plate diverts the flow of fluid into a more intimate contact with the coil to influence the characteristics of the fluid. The mount also comprises a first chamber (94), an elastomeric element 90 bonded to an attachment collar (88) and housing (20). An elastomeric bladder (95) is bonded to a lower surface of the housing to define a second chamber (96). Orifices (98) in housing (92) operate with coil (40) to define a valve for controlling the flow of the MR fluid.
