Fluid encapsulated type vibration isolating device

流体封入式防振装置

Abstract

<P>PROBLEM TO BE SOLVED: To provide a fluid encapsulated type vibration isolating device capable of precluding effectively the noise and/or vibration generated by collapse of pores due to gas-phase separation when an excessive vibration is fed, while a vibration isolating effect is well secured which is exerted on the basis of the resonant effect of the fluid flowing through an orifice passage. <P>SOLUTION: A pressure receiving chamber 58 and an equilibrium chamber 60 are put in communication through the orifice passage 70, and inside the chamber 58 a buffer plate 72 is accommodated which is formed from a porous, resilient member containing continuous pores where at least part of a number of pores is exposed at the surface. <P>COPYRIGHT: (C)2006,JPO&NCIPI
【課題】 オリフィス通路を流動せしめられる流体の共振作用に基づく防振効果を確保しつつ、過大な振動の入力時に気相分離による気泡の崩壊によって発生する異音や振動をより有効に防ぐことが可能とされた流体封入式防振装置を提供することを、目的とする。 【解決手段】 受圧室58と平衡室60とをオリフィス通路70によって連通せしめると共に、多数の気泡のうち少なくともその一部が表面に露出している連続気泡の多孔質弾性体によって形成された緩衝板72を受圧室58内に収容配置した。 【選択図】 図1
