Fluid-filled type vibration damping device |
摘要 |
A fluid-filled type vibration damping device wherein a low-frequency orifice passage and at least one high-frequency orifice passage are formed in a partition member, which is supported by a second mounting member; a valve body is disposed at least at one opening of the high-frequency orifice passage and is provided with a spring member that in a nonloaded state positions the valve body away from the opening of the high-frequency orifice passage to hold the high-frequency orifice passage in an open state; and, at times of vibration input, the valve body is adapted to block the high-frequency orifice passage in opposition to a holding force of the spring member. |
