Claim Text:
1. A gas supply control device for a gas tap having a safety solenoid valve for a cooking or heating apparatus, the gas supply control device including a timing device; a command arrangement operable for manually setting a time interval of opening of the safety solenoid valve of the gas tap; a control element, controllable by the timing device; wherein the gas supply control device is prearranged for use in combination with a gas tap body which includes the safety solenoid valve wherein a solenoid of the safety solenoid valve is configured for electrical connection to a thermoelectric generator designed to generate, in response to heat generated by a flame, an electric current for supplying said solenoid and keeping as a consequence the safety solenoid valve in a respective open condition, wherein the control element is electrically connected between said thermoelectric generator and said solenoid in such a way that, with the control element in a first condition, the electric current generated by the thermoelectric generator reaches the solenoid to keep the safety solenoid valve in said open condition and, with the control element in a second condition, the electric current generated by the thermoelectric generator is interrupted or reduced before reaching the solenoid, thereby causing the safety solenoid valve to pass in a respective closed condition, wherein the timing device, the control element and the command arrangement belong to a control circuit prearranged for electrical coupling with said solenoid, at least one of the timing device and the control element belonging to one functional unit prearranged for mechanical coupling with a portion of the gas tap body which, in an installed condition, is within a housing structure of the apparatus, and wherein the control element is controllable by the timing device to assume said second condition at the end of the time interval set through the command arrangement, for causing an interruption or a reduction of the electric current generated by the thermoelectric generator for supplying said solenoid.
