The invention relates to an inflation or deflation valve 1 to at least a predefined pressure intended to adjust and/or control the pressure of a fluid inside a volume 10, comprising a membrane 4 placed between a first body 2 and a second body 3 connected together by linking means, said membrane delimiting a first chamber 5 with the first body 2 and a second chamber 6 with the second body 3 and pressing, through the action of a spring 18, on a seat delimited by the lower body. The second body 3 comprises intake piping 8 connecting the second chamber 6 to the volume 10 via a valve 9, said piping 8 opening out on the side of the second chamber 6 by the seat 7, at least one calibrated outlet piping being made in the second body so as to make the second chamber 6 communicate with the outside environment to constitute pneumatic means to adjust said predefined pressure. Application to vehicles.
