(JA) 振動減衰ダンパ及びジェットエンジン
Abstract
(EN)
The vibration reduction damper (13) according to the present disclosure is disposed in the interior of a center vent tube (12) having vent holes (12a) which penetrate in the radial direction, and is provided with a sliding part (13a) that comes slidably into contact with the inner wall surface of the center vent tube (12) while avoiding the region in which the vent holes (12a) are formed.
(FR)
L'invention concerne un amortisseur à réduction des vibrations (13) qui est disposé à l'intérieur d'un tube d'aération central (12) ayant des trous d'aération (12a) qui pénètrent dans la direction radiale, et qui est pourvu d'une partie coulissante (13a) qui vient en contact coulissant avec la surface de la paroi interne du tube d'aération central (12) tout en évitant la région dans laquelle les trous d'aération (12a) sont formés.
(JA)
本開示の振動減衰ダンパ(13)は、径方向に貫通する通気孔(12a)を有するセンターベントチューブ(12)の内部に配置され、通気孔(12a)の形成領域を避けてセンターベントチューブ(12)の内壁面に摺動可能に当接する摺動部(13a)を備える。
