Title:
VIBRATION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019070430
Kind Code:
A
Abstract:
To provide a vibration control device which enables damping force occurring when a bound load is input to be different from damping force occurring when a rebound load is input.SOLUTION: A partition member 17 includes: a membrane 31 forming a part of a partition wall of a main liquid chamber 15; an intermediate chamber 35 located at the opposite side of the main liquid chamber 15 across the membrane 31 and having the membrane 31 at a part of the partition wall; a first orifice passage 21 allowing communication between the main liquid chamber 15 and the intermediate chamber 35; and a second orifice passage 22 allowing communication between the intermediate chamber 35 and a sub liquid chamber 16. The partition member 17 includes an inhibition member 26 which inhibits one of expanding deformation of the membrane 31 to the intermediate chamber 35 side and expanding deformation to the main liquid chamber 15 side.SELECTED DRAWING: Figure 1
