How does a shock absorber work?

[Brad Hogg <roadhogg@xxxxxxx>]

An air shock is a shock absorber with an added component that is capable of 
adjusting ride height.  A shock CANNOT adjust ride height as it is.

As you say certain gas shocks can change the ride height. Such as "air 
shocks" where the air pressure in the shock can be regulated to control ride 
height and action. Used by hot rodders a lot. Aircraft landing gear are in 
fact big air shocks with a mineral oil acting as the dampner and the 
nitrogen charge acting as the spring. And you adjust the height of the 
"spring" by putting the nitrogen precharge at a certain pressure(depends on 
the weight of the aircraft at the time of charging) or put a standard 
pressure on it with the aircraft on jacks. Sorry for the ramble but I 
couldn't help it.
