Title:
SEALED FLUID VIBRATION DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/076024
Kind Code:
A1
Abstract:
A sealed fluid vibration damping device (10) wherein a switching passage (72) is formed connected in series to a second orifice passage (74), a switching valve (76) is arranged in the switching passage (72) in a manner such that the switching passage (72) remains in the connected state, and the switching valve (76) switches the switching passage (72) between the connected state and the disconnected state in accordance with the amplitude of the input vibration. The resonance frequency of the switching passage (72) in which the switching valve (76) is arranged is set to a higher frequency than the tuning frequency of the second orifice passage (74).
