Default Thought about absorbers .

During the compression , spring's force gradually go up . But the same time oil's damping is constant.

I think that it is better to have gradually damping from the oil as in spring.
If I have ( ... I have ) a mode to modify the bore of piston's hole ,at first big bore and gradually to small , ... thats it.


What do you think ?

I talk about special absorbs and not common parts ( ... for crazy users only ).


I hope that you can understand what I'm (try ) saying , with 'my english'

mmm so the piston will have to reduce in size as it goes up???

i dont think that would change it. the fluid would fill the bore and end result would be the same resistance as a small hole. I think it would need to be a 2 stage shock with 2 pistons. when the the shaft moves a certain distance then it starts to move the second one with smaller holes to increase the resistance. But of course this is backwards of what you want to do. You would want to decrease the piston resistance on compression since the springs resistance is increasing.

I tried the absorb with 1mm bore ,piston's hole , and with 2,5mm bore. There was a great difference between these two.
So if I'll modify gradually the bore between these bores ? Result would be the same ?

I see what you mean Vassilis, but I don't think it will make a difference if you make the hole tapered.

My understanding of it is (as described by QSL):
The oil would still pass through the smallest part of the hole at the same rate as it would if the entire hole was that size.

I've seen cars that have got 2 shocks for each wheel.
I gather they're rated differently and one of them is softer than the other.
One would compress to a certain point and then the other one kicks in after that.

Maybe someone can shed some more light on this theory?
