ABSTRACT:
A mounting device includes an elastomeric body formed with first and second recesses which define a working chamber and an expansion chamber which are filled with an ERF (electrorheological). The recesses are enclosed by an annular member to define the chambers. First and second helical orifice passages formed about the periphery of the annular member fluidly connect the chambers. A cylindrical outer casing which encloses the elastomeric body and annular member is grounded to act as a first electrode. Strips disposed in the orifice passages act as electrodes on which voltages can be selectively and separately impressed.
