Regulator, On citroens of hydraulic type decied where and when hyd pressure is required and dishes it out as needed, an accumulator 'regulator' sphere is what holds the spare pressure for the systems requirements (or if its an older car a regulator could be what controls the alternator voltage but probably not what you meant)

The pressure regulator monitors the line pressure, and when it is sufficient, allows all the output from the pump to go straight back to the reservoir - 'cut-out' This makes the 'click' that you hear. When line pressure has been used by the suspension, steering, or brakes, and falls to the 'cut-in' pressure, the valve in the regulator closes and the pump output goes to the line again.
The sphere is actually an 'accumulator' sphere, and it is there because liquids like LHM are incompressible, so it acts as a reservoir for pressure. Although it is attached to the regulator for convenience, it could have been atttached to the main hydraulic line anywhere. DS folk sometimes relocate it.
If the sphere was not present, then as soon as half a spoonful of LHM had been used for, say, braking, the pressure would drop and the reg would cut in again. This is what happens if the sphere fails.
