Abstract
A pneumatic pressure regulator comprised of at least an obturator actuated by at least an elastic membrane comprised of at least an inlet orifice which permits the entry of a fluid under pressure and comprises at least an outlet orifice which permits the exit of a fluid under regulated pressure, characterized by a programmable means (6) which creates a force F on the obturator (2), this force F being defined at the end of a test by varying the value of at least a parameter P of the functioning of the regulator in such a manner that the outer pressure PS=f(P) of the regulator is exactly equal to the value of the predefined pressure PD=f(P) for each value of the parameter P of the operation of the regulator.
