HOW MANY SPHERES DOES MY CITROEN C5, MY XANTIA OR XM HAVE ?

.

If you are not sure how many suspension spheres your CITROËN has, our technicians are on hand to help you with the number, calibration and location of your suspensions. Hydractive or not, sport or flexibility position, our team can provide you with information and help you place the perfect order, to restore your CITROËN and its hydraulic circuit to its original efficiency. The number of spheres depends on the hydractive system. To determine whether or not your CITROEN is hydractive, consult our FREQUENTLY ASKED QUESTIONS in which you will find all the answers on this subject.

WHAT IS THE DIAPHRAGM FOR INSIDE MY HYDRAULIC SPHERE ?

.

A sphere is separated into two distinct parts (two hermetic compartments) by an extremely resistant deformable elastomer membrane. The upper part of the sphere is filled with nitrogen (non-toxic and non-flammable gas), and the lower part of the part is filled with LHM oil. A hole equipped with valves in the bottom of the sphere, allows the passage of oil through the cylinder, up to the jack. Once your Citroën has been started and heated, the oil is under pressure, thanks to the pump. It then puts pressure on the membrane and compresses the nitrogen until a perfect balance is reached. Once underway, the nitrogen pushes the LHM back, which returns the suspension arms (via the piston) to their starting position. The engine, meanwhile, drives a high pressure pump coupled to an accumulator, which is responsible for distributing the hydraulic fluid under high pressure in the various systems, such as braking, steering assistance, etc.
