The reservoir pressurization system gets:
-HP air (usual operation)
-LP air (if failure of left engine occurs)
-ground supply air.
A restrictor is installed in the HP bleed air line from the left engine. The restrictor limits the airflow to make sure that the temperature of the HP air is reduced to a satisfactory level. It also prevents too much bleed air leakage. This is necessary in case of a leak downstream of the restrictor.
The system has a reservoir pressurization unit which controls the pressure of the air supplied to the reservoirs. This is necessary because the pressure of the HP air from the engine can be as much as 26 bar (377 psi) and the system operates at 4.5 bar absolute. The pressure of the LP bleed air is 3.5 bar relative. Thus it is not necessary to decrease the pressure of this air supply.
