The valve in automatic shutoff valve mechanism is held in a predetermined elevated open position by a magnet spaced above the valve, and the valve can be released for downward movement into shutoff position either by melting of a fusible nut holding a threaded magnet-supporting stem or by the mechanism being vibrated sufficiently severely to shake the valve loose from the attraction of the magnet.

anne d'un mécanisme automatique de vanne d'arrêt. Elle se trouve, sous l'action d'un aimant placé au-dessus de la vanne, dans une position soulevée, déterminée à l'avance, qui est sa position ouverte, et elle peut être relâchée pour effectuer un mouvement descendant vers sa position de fermeture, soit par la fusion d'un écrou fusible portant une tige à laquelle se rattache un aimant, soit en faisant vibrer le mécanisme assez vigoureusement pour que la vanne, sous l'action de cette secousse, échappe à l'attraction de l'aimant.
