Abstract: This safety ignition device intended notably for controlling the valve through which gaseous fuel is supplied to a burner injector comprises essentially built-in means for protecting the circuitry from transient overvoltages and current surges, notably a varistor for limiting peak voltages and currents, absorbing disturbing energies and stabilizing pressures.

Abstract: A safety ignition valve for a pilotless burner comprises a valve body having an inlet for connection to a fuel supply, an outlet for connection to the burner and a valve seat between the inlet and outlet. A valve member is movable between a closed position in which it is seated on the valve seat and an open position in which it is spaced from the valve seat. A spring acting on the valve member biases it toward closed position. A first solenoid which is energized by current produced by a thermocouple heated by the burner acts on the valve member to hold it in open position against the bias of the spring. A second spring solenoid located in a control box fixed to the valve body actuates a plunger for moving the valve member to open position when the second solenoid is energized.
