FLUID-FILLED VIBRATION DAMPING DEVICE |
| 摘要 |
A fluid-filled vibration damping device including: a primary liquid chamber which gives rise to pressure fluctuations based on deformation of a main rubber elastic body at times of vibration input; an auxiliary liquid chamber which gives rise to pressure fluctuations relative to the primary liquid chamber at times of vibration input; and an orifice passage that allows flow action of a scaled fluid between the primary liquid chamber and the auxiliary liquid chamber. The sealed fluid contains at least 0.03 volume % of a dissolved gas under atmospheric pressure at room temperature. A low-adhesion energy surface with a water contact angle of at least 90 degrees is provided on an inner surface of the primary liquid chamber. |

1. A fluid-filled vibration damping device comprising:
a primary liquid chamber which gives rise to pressure fluctuations based on deformation of a main rubber elastic body at times of vibration input; an auxiliary liquid chamber which gives rise to pressure fluctuations relative to the primary liquid chamber at times of vibration input; and an orifice passage that allows flow action of a sealed fluid between the primary liquid chamber and the auxiliary liquid chamber, wherein the sealed fluid contains at least 0.03 volume % of a dissolved gas under atmospheric pressure at room temperature, and a low-adhesion energy surface with a water contact angle of at least 90 degrees is provided on an inner surface of the primary liquid chamber. |
