Title (EN) LIQUID-SEALED VIBRATION-ISOLATING DEVICE
(FR) DISPOSITIF ANTI-VIBRATION SCELLÉ DE FAÇON ÉTANCHE VIS-À-VIS DES LIQUIDES
(JA) 液封入式防振装置
Abstract:
(EN) A partition body (40) for separating a first liquid chamber (36A) and a second liquid chamber (36B) from each other comprises an annular, orifice forming member (44), an elastic wall (46) for closing the opening defined by the inner peripheral surface (44A) of the orifice forming member, and a pair of partition plates (48, 50) for sandwiching the elastic wall. The elastic wall (46) is provided with a through-hole (74) provided in a portion of the elastic wall, said portion being sandwiched by the partition walls (48, 50). Gaps (78) which connect to the through-hole (74) are provided between the wall surface of the elastic wall (46) and the surfaces of the partition plates (48, 50). When the partition plates (48, 50) are at neutral positions, the first liquid chamber (36A) and the second liquid chamber (36B) are connected to each other through the through-hole (74) and the gaps (78) in such a manner that a liquid can flow through the through-hole (74) and the gaps (78), and the through-hole (74) is closed by displacement of the partition plates (48, 50).
(FR) L'invention porte sur un corps de séparation (40) pour séparer une première chambre de liquide (36A) et une seconde chambre de liquide (36B) l'une de l'autre, lequel corps comprend un élément formant orifice annulaire (44), une paroi élastique (46) pour fermer l'ouverture définie par la surface périphérique interne (44A) de l'élément formant orifice, et une paire de plaques de séparation (48, 50) pour prendre en sandwich la paroi élastique. La paroi élastique (46) comporte un trou traversant (74) disposé dans une partie de la paroi élastique, ladite partie étant prise en sandwich par les parois de séparation (48, 50). Des intervalles (78) qui sont reliés au trou traversant (74) sont prévus entre la surface de paroi de la paroi élastique (46) et les surfaces des plaques de séparation (48, 50). Lorsque les plaques de séparation (48, 50) se trouvent en des positions neutres, la première chambre de liquide (36A) et la seconde chambre de liquide (36B) sont reliées l'une à l'autre par le trou traversant (74) et les intervalles (78) d'une manière telle qu'un liquide peut s'écouler à travers le trou traversant (74) et les intervalles (78), et le trou traversant (74) est fermé par déplacement des plaques de séparation (48, 50).
(JA)  第1液室36Aと第2液室36Bを仕切る仕切り体40は、環状のオリフィス形成部材44と、その内周面44Aの間を塞ぐ弾性壁46と、弾性壁を挟み込む一対の仕切り板48,50とからなる。弾性壁46には、仕切り板48,50によって挟み込まれる弾性壁部分に貫通穴74を設けられる。弾性壁46の壁面と仕切り板48,50の板面との間に貫通穴74に繋がる隙間78を設けて、仕切り板48,50の中立位置では第1液室36Aと第2液室36Bが貫通穴74と隙間78を介して液体流動可能に繋げられ、かつ仕切り板48,50の変位によって貫通穴74が塞がれるよう構成する。
