、振動入力に応じて変形するゴム体を室壁とする
一対の液室を設けてなる液封入防振装置において
、上記各液室内に電界の強さに応じて粘度が変化
する電気粘性流体を封入するとともに、両液室を
少なくとも断面積ないし長さが異なる複数の絞り
流路により連通せしめ、かつ上記各絞り流路には
、流路内に電界を形成する電極を付設してこれら

装置。 In a liquid-filled vibration isolator, a pair of liquid chambers each having a chamber wall made of a rubber body that deforms in response to vibration input is provided between an inner and outer double cylinder each connected to a vibrating body, and an electric field is generated in each of the liquid chambers. An electrorheological fluid whose viscosity changes depending on the strength of the fluid is sealed, and both liquid chambers are communicated by a plurality of constricted channels having at least different cross-sectional areas or lengths, and each of the constricted channels includes a flow channel. A liquid-filled vibration isolator that is equipped with electrodes that form an electric field within the device and controls the supply of electricity to these electrodes.
