Abstract

AMORTISSEUR CONSTITUE D'UN MANCHON REMPLI DE PARTICULES QUI S'ACCUMULENT CONTRE LES ORIFICES DE SORTIE DU GAZ. L'APPAREIL EST CONSTITUE D'UN MANCHON 1 MONTE SUR UN RACCORD FILETE 2. IL CONTIENT UNE PORTION DE CYLINDRE CIRCULAIRE 4 LIMITEE PAR UN DIEDRE DE MOINS DE 360 AYANT SON ARETE SUR L'AXE 5. UNE GRILLE 7 FORME EGALEMENT UN CYLINDRE PARTIEL PAR OU L'AIR ENTRE DANS LE MANCHON 1. IL EN SORT PAR LES OUVERTURES PERIPHERIQUES 3, APRES AVOIR TRAVERSE UNE COUCHE DE PARTICULES 6 QUI S'ACCUMULENT DEVANT LES OUVERTURES.SHOCK ABSORBER CONSISTS OF A SLEEVE FILLED WITH PARTICLES THAT ACCUMULATE AGAINST THE GAS OUTLET OPENINGS. THE APPLIANCE CONSISTS OF A SLEEVE 1 MOUNTED ON A THREADED FITTING 2. IT CONTAINS A PORTION OF CIRCULAR CYLINDER 4 LIMITED BY A DIHEDRAL OF LESS THAN 360 HAVING ITS EDGE ON AXIS 5. A GRID 7 ALSO FORM A PARTIAL CYLINDER THROUGH WHERE THE AIR ENTERS SLEEVE 1. IT EXITS THROUGH PERIPHERAL OPENINGS 3, AFTER PASSING THROUGH A LAYER OF PARTICLES 6 WHICH ACCUMULATE IN FRONT OF THE OPENINGS.
