In the method for extinguishing fires in enclosed spaces, pre-cooled combustion products are introduced into an enclosed space until in the enclosed space there is an atmosphere that prevents combustion. An ecologically acceptable and fire-inhibiting medium that is not detrimental to health is formed by oxidising the combustion products completely by means of an oxygen-containing oxidising agent prior to cooling. An apparatus for implementing the method has a housing which is divided by a transversely running partition wall having at least one wall opening. At the at least one wall opening a mixing tube is mounted coaxially with respect to a discharge nozzle connected to a combustion chamber, the end of the mixing tube remote from the partition wall opening into the atmosphere. The space between the mixing tube and the inner wall of the housing is filled with a coolant. Inlet openings are formed in the wall of the housing between the partition wall and the end face of the combustion chamber facing the partition wall. The discharge nozzle is in the form of a jet pipe and extends through the wall opening into the mixing tube, a gap being present between the jet pipe and the mixing tube.

Cette invention concerne une méthode d'extinction des flammes en milieu fermé, caractérisée par l'introduction dans l'espace fermé d'une quantité de produits de combustion pré-refroidies telle que la combustion n'y soit plus possible. Un agent extincteur écologique et non préjudiciable à la santé est obtenu en oxydant complètement les produits de combustion en les mettant en contact avec un agent oxydant oxygéné avant le refroidissement. L'appreil servant à mettre en oeuvre la méthode objet de l'invention comporte un corps divisé en deux parties par une cloison transversale comportant au moins une ouverture. Vis-àvis cette ouverture se trouve un tube mélangeur monté coaxialement à un diffuseur raccordé à une chambre de combustion, le bout du tube mélangeur étant en retrait de la cloison. L'espace entre le tube mélangeur et la paroi intérieure du corps est rempli de réfrigérant. Des ouvertures d'admission sont ménagées dans la paroi du corps entre la cloison intérieure et la façade correspondante de la chambre de combustion. Le diffuseur, qui se présente sous la forme d'une tuyère d'éjection, traverse l'ouverture prévue dans la cloison et son extrémité pénètre dans le tube mélangeur, un espace annulaire étant conservé entre ces derniers.
