Abstract (en)
[origin: EP1094276A1] Each gas tap is controlled by a safety electro-valve (4), of a size which can be located in a pipe (5). The valve includes an electromagnet (41) and a sealing washer (42), which closes the gas output passage, through the action of a spring which maintains the washer in closed position to block gas flow from the gas output (21). An electronic controller (6) supplies current to the windings of the electro-valves so that the washer is attracted towards the valve, against spring counteraction to allow opening of the gas output passage (21). The electronic controller (6) includes a part (61) which controls the electrical power dissipated in the winding of each electro-valve as a function of time from the start of opening of the gas passage. An Independent claim is also included for the hotplate burners.
