Abstract: front page image
(EN)A liquid-sealed type vibration isolator provided with a first orifice flow path (56) and a second orifice flow path (60), wherein a valve member (66) constructed from a rubber-like elastic diaphragm and opening and closing the second orifice flow path (60) is provided to a partitioning body (40) so as to be perpendicular to the direction of flow through the second orifice flow path. The valve member is sandwiched and held at the outer periphery thereof between wall surfaces of a valve containing chamber (68) and has, on the inner side of the outer periphery thereof, a diaphragm portion (66B) deflected by a liquid flow in the second orifice flow path. Deflection of the diaphragm portion (66B) closes openings (60C, 60D) in the second orifice flow path. A communicating hole (76) communicating with the second orifice flow path is provided at a position not superposed on the openings in the diaphragm portion (66B). Characteristics of the liquid-sealed type vibration isolator can be switched between each other by the low cost structure above.
(FR)L’invention concerne un amortisseur de vibrations du type à joint hydraulique muni d’un premier passage d’orifice (56) et d’un second passage d’orifice (60), un élément soupape (66) constitué d’une membrane élastique de type caoutchouc et ouvrant et fermant le second passage d’orifice (60) étant agencé sur un corps de séparation (40) de manière à être perpendiculaire à la direction d’écoulement à travers le second passage d’orifice. L’élément soupape est intercalé et maintenu à sa périphérie externe entre des surfaces de paroi d’une chambre de soupape (68) et présente, sur le côté interne de sa périphérie externe, une partie membrane (66B) déviée par un écoulement de liquide dans le second passage d’orifice. La déviation de la partie membrane (66B) ferme les ouvertures (60C, 60D) dans le second passage d’orifice. Un trou de communication (76) avec le second passage d’orifice est agencé en une position non superposée sur les ouvertures dans la partie membrane (66B). Les caractéristiques de l’amortisseur de vibrations du type à joint hydraulique peuvent être modifiées au moyen de la structure peu coûteuse ci-dessus.
(JA) 第1オリフィス流路56と第2オリフィス流路60を備えた液封入式防振装置において、第2オリフィス流路60を開閉するゴム状弾性膜からなる弁部材66を、第2オリフィス流路の流れ方向に直交するように仕切り体40に設ける。弁部材は、外周部が弁収容室68の壁面で挟持されるとともに、外周部の内側に第2オリフィス流路内の液流動によって撓み変形する膜部分66Bを備え、膜部分66Bが撓み変形することで第2オリフィス流路の開口60C,60Dを閉塞する。膜部分66Bの上記開口に対して重ならない位置に第2オリフィス流路を連通させる連通穴76を設ける。これにより、安価な構造で特性を切り替え可能とする。
