ABSTRACT:
A body of electrorheological ("Smart") fluid is disposed between hydraulic fluid within a hydraulic elevator system, and a chamber filled with pressure absorbing fluid. By introducing a field within the Smart fluid to maintain the Smart fluid in a given phase, the Smart fluid transmits the pulsations from the hydraulic fluid to the pressure absorbing fluid as a function of the pulsations.
