It is done by allowing fluid to flow through passages between chambers separated with a piston. Your car’s shocks and struts work the same way. There are also ones with external reservoir that may allow for more travel or that can be pressurized to alter resistance.
The fluid pushes on a reservoir of nitrogen that keeps the plane from bottoming out. It is a progressive pressure system, so it gets harder to move the more force is applied.
Ah! Yes, you didn’t mention the pneumatic component. I thought you just meant between two bodies of oil, which would only provide damping and some added moment.
How would hydraulic ones work? The entire concept there is that liquids are almost incompressible.

You’d still need some kind of restoring force. Visibly, some cars use metal springs for at least part of that.
