Has anyone ever heard of/used an accumulator set up for air suspension? With hydraulic setups, it's fairly common to soften the ride, but what about for air? I can't seem to find any online to begin with, which leads me to think this isn't too common. I want to smooth out a rough ride, and it has been suggested that I have accumulators installed between the valves and struts.

Accumulators for air suspension?

How would I go about installing these accumulators? Would I add them inline between the valves and struts? If so, every time I were to increase or decrease pressure to the struts, I would be increasing/decreasing pressure in the tank as well?
Reason I need accumulators is I am running cans in the rear and air struts in the front. I got into a bit of a money pinch and had the cylinders laying around [got them in a bundle for a trade], so I'm rolling with them for a few months until I can pick up a set of rear air struts. They work quite well actually, they're just rough.

You're going to want to be cautious to not add too large a tank that you bring your effective instantaneous spring rate down too low, however. This is likely to require a combination of some rough math and some trial-and-error.

Originally posted by Oh Damn, it's Sam View PostCorrect on both accounts. All you'd be doing is adding a small tank inline on the line that runs from your valve to your cylinder. The effective instantaneous spring rate of an air bag / strut / cylinder / whatever is roughly proportional to the ratio between the volume of the cylinder at ride height and the cylinder when compressed. By adding a tank inline, you're decreasing that ratio.

I ran cans on one of my cars and used small tanks inline as well...worked fine.*~* Yamaguchi-gumi Syndicate Member #59,005 *~*// Bippu-Car \\
