Title (EN) LIQUID ENCLOSED ANTIVIBRATION DEVICE
(FR) DISPOSITIF ANTIVIBRATION ENTOURÉ DE LIQUIDE
(JA) 液封入式防振装置
Abstract: front page image
(EN)Disclosed is a liquid enclosed antivibration device (10) comprised of a primary liquid chamber (34A), a part of the wall of which is defined by an antivibration base element (16); a secondary liquid chamber (34B), a part of the wall of which is defined by a diaphragm (36); a partition element (38) provided between the primary liquid chamber (34A) and the secondary liquid chamber (34B); and an orifice passage (40) provided so that the primary liquid chamber (34A) is in communication with the secondary liquid chamber (34B), wherein an elastic membrane (42) is provided in the partition element (38); and the elastic membrane (42) is composed of a rubber composition including butyl rubber or halogenated butyl rubber. Thus, the noise caused by the collision of the elastic membrane (42) is reduced.
(FR)L'invention porte sur un dispositif antivibration entouré de liquide (10) constitué par une chambre de liquide primaire (34A), dont une partie de la paroi est définie par un élément antivibration de base (16) ; une chambre de liquide secondaire (34B), dont une partie de la paroi est définie par un diaphragme (36) ; un élément de séparation (38) disposé entre la chambre de liquide primaire (34A) et la chambre de liquide secondaire (34B) ; et un passage d'orifice (40) disposé de telle sorte que la chambre de liquide primaire (34A) est en communication avec la chambre de liquide secondaire (34B), une membrane élastique (42) étant disposée dans l'élément de séparation (38) ; et la membrane élastique (42) étant constituée par une composition de caoutchouc comprenant du caoutchouc de butyle ou du caoutchouc de butyle halogéné. Ainsi, le bruit provoqué par la collision de la membrane élastique (42) est réduit.
(JA) 防振基体16が室壁の一部をなす主液室34Aと、ダイヤフラム36が室壁の一部をなす副液室34Bと、主液室34Aと副液室34Aを仕切る仕切り体38と、主液室34Aと副液室34Bとを連通させるオリフィス流路40と、を備えた液封入式防振装置10において、前記仕切り体38に弾性メンブレン42を設け、前記弾性メンブレン42をブチルゴム又はハロゲン化ブチルゴムを含むゴム組成物により形成する。これにより、弾性メンブレン42の衝突に起因する異音を低減する。
