The pressures on the A-side are held at approx. 2 bar by the
“regulating” air conditioner compressor even at differing engine speeds.
This applies however only within the rated range of the air conditioner
compressor ; if the rated range of the air conditioner compressor is
exceeded, the pressure will increase

Note
In vehicles with air conditioner compressor regulating valve -N280-,
the pressure on the low-pressure side is varied by activating the valve. |
