摘要
A regulating apparatus and a regulating method for regulating the internal pressure P.sub.i of a ventilated, closed volume subjected to variations in external pressure P.sub.e, the apparatus including at least two compensation circuits enabling the intake air flow rate q.sub. 1 and the extraction air flow rate q.sub.2 to be adjusted in real time so that the difference between these two flow rates algebraically compensates for the leakage flow rate q.sub.f, and maintains the internal pressure P.sub. i inside the volume at a constant level.
