Abstract

L'invention concerne un filtre anti-flamme (10) comprenant deux corps partiels (12,14) constitués de différentes couches de tissu métallique (11,13), lesquels corps partiels étant assemblés par une couche intermédiaire (15) en tissu métallique de mailles particulièrement grosses. Le tissu métallique à grosses mailles est constitué, de préférence, d'un fil métallique épais. Aussi bien le diamètre du fil que la largeur de maille de cette couche intermédiaire (15) sont, de préférence, nettement supérieurs à la largeur de maille et au diamètre des fils utilisés pour le corps partiel (12,14). Le corps de décompression (10) selon l'invention allie une grande stabilité mécanique à une grande sécurité contre tout retour de flamme et simultanément à une très faible résistance d'écoulement.
