How does hydropneumatic suspension work?

I’m training for a career change to become a mechanic and I’m especially interested in older European vehicles. How does hydropneumatic suspension work?

Hydropneumatic suspension works by pressurizing a special fluid that can power the suspension, the brakes, power steering, and more.
Instead of a spring and shock absorber, hydropneumatic suspension uses spheres that trap gas and use hydraulic fluid on the other side. As a technology, this was revolutionary when it first came out! Instead of springs, there was now a suspension system based on fluid.
Manufacturers like Citroen, Rolls-Royce, Maserati, and Peugeot use this type of suspension. Today, it’s infrequently used in consumer vehicles but many classic vehicles still utilize hydropneumatic suspension—so it’s a good idea to learn about it for your second career!
Repairs on this type of system are highly complex. This could be a lucrative field if you can acquire the right expertise!
