ベローズ式ダンパ
Document Type and Number:
Japanese Patent JP7128027
Kind Code:
B2
Abstract:
To provide a bellows type damper which enables connection with a vibration attenuation object member in a simple configuration.SOLUTION: A bellows type damper includes: a first bellows filled with a fluid in its internal cavity and expandable and contractible in an axial direction, a second bellows; a first end plate disposed on an axial one end side of the first bellows and closing an opening of an axial one end side of the internal cavity of the first bellows; an intermediate plate having an orifice, disposed between the axial other end side of the first bellows and an axial one end side of the second bellows, and coaxially connecting the first bellows and the second bellows; and a second end plate disposed on the axial other end side of the second bellows and closing an opening at the axial other end side of an internal cavity of the second bellows. The internal cavity of the first bellows is communicated with the internal cavity of the second bellows by the orifice, the internal cavities of the first bellows and the second bellows are sealed, and an effective cross-sectional area of the first bellows is different from an effective cross-sectional area of the second bellows.SELECTED DRAWING: Figure 1
