Abstract
【解決手段】受圧室42と平衡室44を仕切る仕切部材40によって可動ゴム膜66の外周縁部70を保持せしめる一方、該仕切部材40に設けられて該可動ゴム膜66の一方の面に該受圧室42の圧力を及ぼす受圧室側窓部52と該仕切部材40に設けられて該可動ゴム膜66の他方の面に該平衡室44の圧力を及ぼす平衡室側窓部58によって第二のオリフィス通路75を形成すると共に、該可動ゴム膜66の弾性変形に基づいて該第二のオリフィス通路75通じて流動せしめられる流体の共振周波数に比して、該可動ゴム膜66の弾性変形の固有振動数を高周波側に設定した。

Description
Claims (3)
- 第一の取付部材と第二の取付部材を本体ゴム弾性体で連結せしめ、該本体ゴム弾性体で壁部の一部が構成されて振動入力時に圧力変動が生ぜしめられる受圧室と、壁部の一部が可撓性膜で構成されて容積変化が許容される平衡室を、該第二の取付部材で支持された仕切部材を挟んだ両側に形成して、それら受圧室と平衡室に非圧縮性流体を封入すると共に、該受圧室と該平衡室を相互に連通する第一のオリフィス通路を該仕切部材の外周に設ける一方、該仕切部材の中央部分に可動ゴム膜を配設すると共に、該可動ゴム膜の一方の面に該受圧室の圧力を及ぼす受圧室側窓部と該可動ゴム膜の他方の面に該平衡室の圧力を及ぼす平衡室側窓部とを該仕切部材に設けて圧力吸収機構を構成した流体封入式防振装置において、
前記仕切部材によって前記可動ゴム膜の外周縁部を保持せしめる一方、前記受圧室側窓部と前記平衡室側窓部によって第二のオリフィス通路を形成すると共に、該可動ゴム膜の弾性変形に基づいて該第二のオリフィス通路を通じて流動せしめられる流体の共振周波数に比して、該可動ゴム膜の弾性変形の固有振動数を高周波側に設定したことを特徴とする流体封入式防振装置。 - 前記仕切部材によって前記可動ゴム膜の外周縁部及び中央部分を狭圧保持せしめると共に、該仕切部材における前記受圧室側窓部の開口面積を、該可動ゴム膜における可動部分の面積の1/3〜1/2の範囲内に設定した請求項1に記載の流体封入式防振装置。
- 前記第二のオリフィス通路を通じて流動せしめられる流体の共振周波数を50Hz〜200Hzの範囲内に設定すると共に、前記可動ゴム膜の弾性変形の固有振動数を200Hz〜500Hzの範囲内に設定した請求項1又は2に記載の流体封入式防振装置。
