Class Information
Number: 188/282.4
Name: Brakes > Internal-resistance motion retarder > Resistance alters relative to direction of thrust member (e.g., high resistance in one direction, low in the other) > Via valved orifice in thrust member > Valve actuated by electrical system > System having distinct selections (e.g., hard, medium, soft)
Description: Electrically actuated valve in which the voltage and current moves the element based on a particular choice that determines the degree of damping.
