Illustration showing a monotube damper and nitrogen chamber collapse if insufficient gas pressure is present leading to hysteresis original by TEIN modified by Fat Cat Motorsports

Diagram showing behavior of the nitrogen gas chamber as the shaft & piston assembly move into the damper body. Too little gas pressure will allow the Oil Chamber to collapse the Gas Chamber, which gives a momentary drop in compression force and feeling of being unsupported by the suspension. However, too much gas pressure causes excessive initial stiffness in compression movement. Both behaviors can be avoided through using Ripple Reducer (adding carefully sized, very small holes to the bottom of the piston facing the Gas Chamber) which relieves pressure as the Piston moves through the Oil, reducing the likelihood of Gas Chamber collapse and minimizing the presence of hysteresis on the dyno graph plus in the occupant’s experience.
