Abstract
A method of designing a valve presenting an orifice of section that depends on the position of the valve member of the valve, which section can thus be controlled. The method includes determining a desired variation relationship for the flow section of the valve, which relationship defines a desired variation in the section as a function of time; setting a predetermined movement relationship for the valve member; and defining the shape of the fluid flow orifice in such a manner that, at each instant, if the valve member moves in compliance with the predetermined movement relationship, the flow section remains equal to the desired section. The method makes it possible to design a valve that is simple to control.
