초록 ▼

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.

대표청구항 ▼

A method for modulating the flow rate of an injector of a fuel gas burner, comprising the steps of: arranging a fluid-tight casing in a passageway through which fuel gas is conveyed to the fuel gas burner, providing said fluid-tight casing with inlet and outlet connecting neck fittings for an inlet flow of the fuel gas from said passageway and an outlet flow of the fuel gas to said passageway, respectively, mounting an electrically controlled valve member in said fluid-tight casing movable between a position opening said passageway and a position closing said passageway, providing an electromagnet in said fluid-tight casing for moving said valve member in a reciprocating relationship in order to open and close said outlet connecting neck fitting and thus said passageway, said valve member being mounted in said fluid-tight casing through the agency of a flexible strip constantly biased by a spring towards said closing position of said valve member, said spring having a first end closest to said electromagnet and a second end, opposite to said first end, built into said fluid-tight casing, maintaining the frequency of the displacements of the valve member toward said opening position constant, varying the time period in which the valve member is maintained in said closing position in accordance with a desired flow rate of the flue gas, and selecting the constant frequency of the displacement of the valve member toward said opening position in a range from about 20 Hz to about 30 Hz to prevent the flame of the burner from being extinguished in operation.
