Abstract
A method of continuously modulating a fluid flow rate by means of an electrically controlled sequential valve, consisting in reciprocating the electrically controlled valve provided in a passageway conveying the fluid towards an apparatus to be fed therewith, between a position opening and a position closing said passageway, the frequency of the displacements towards either one of the valve positions being constant whereas the period of holding of the valve in the other position varies in accordance with the flow rate to be obtained, the method being applicable to the adjustement of the flow rate of a fluid such as a gas for a cooking apparatus for instance.
