Actually this isn't quite right. The diaphram is there to prevent the damper from hydraulically locking when it is compressed. This is because as the piston rod enters the damper it takes up space, and oil is incompressible, so the diaphram and air behind it allows for this. Any change in pressure is so small is has pretty much no effect.
If you take a bleed type damper like an AE with bleed cap and lock the bleed screw before the damper is compressed fully you won't be able to push it in any further.
