Title:
振動抑制装置
Document Type and Number:
Japanese Patent JP6869620
Kind Code:
B2
Abstract:
To provide a vibration suppression device capable of sufficiently generating reaction force without increasing a pressure receiving area of a piston to a working fluid, and properly suppressing vibration.SOLUTION: Each of a plurality of cylinders filled with working fluids is divided into two fluid chambers by each of a plurality of pistons, force in a direction to selectively slide each piston to one side or the other side of two fluid chambers is acted according to a direction of relative displacement when the relative displacement is transmitted to each cylinder and each piston, each one of two fluid chambers of each cylinder is communicated with the other by a first communication passage, each one of two fluid chambers of each cylinder is communicated with the other by a second communication passage, an introduction communication passage is communicated to the first and second communication passages, each of the communication passage is filled with the working fluid, and pressure difference of the working fluid in two fluid chambers in each cylinder is adjusted by a pump through the introduction communication passage, and the first and second communication passages.SELECTED DRAWING: Figure 6
