Abstract (en)
[origin: US4382773A] 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 (fr)
L'invention concerne un dispositif d'allumage de sécurité destiné à une valve pour brûleur. Ce dispositif d'allumage comprend des moyens intégrés de protection contre les surtensions transitoires notamment un varistor J permettant de limiter les tensions et les courants de choc, d'absorber les énergies perturbatrices et de stabiliser les tensions.
