FLUID DAMPER
PROBLEM TO BE SOLVED: To provide a fluid damper capable of obtaining a damping force satisfactorily even when a fluid pressure regulation device cannot elevate a pressure of working fluid in a fluid chamber due to a failure or the like.SOLUTION: First and second pistons 3, 4 are freely movably provided in the shaft line direction in a fluid chamber partitioned by a pair of wall parts 2b, 2c in a cylinder 2. The fluid chamber is divided into a first fluid chamber 2e, a second fluid chamber 2f and a third fluid chamber 2g by the first and second pistons 3, 4 and, in the first to third fluid chambers 2e to 2g, working fluid HF is filled. A first communication path 10 for causing the working fluid HF to flow between the first fluid chamber 2e and the second fluid chamber 2f is communicated with the first and second fluid chambers 2e, 2f, a second communication path 11 for causing the working fluid HF to flow between the fluid chamber 2f and the third fluid chamber 2g is communicated with the second and third fluid chambers 2f, 2g, and pressures of the working fluid HF in the first and second fluid chambers 2e, 2f are regulated by a fluid pressure regulation device 12.SELECTED DRAWING: Figure 1
【課題】流体圧調整装置が故障などにより流体室内の作動流体の圧力を高めることができないような場合でも、減衰力を十分に得ることができる流体ダンパを提供する。【解決手段】シリンダ2内に一対の壁部2b,2cで画成された流体室に、第１及び第２ピストン3,4が軸線方向に移動自在に設けられている。流体室は、第１及び第２ピストン3,4により、第１流体室2e、第２流体室2f及び第３流体室2gに区画されており、第１〜第３流体室2e〜2gには、作動流体HFが充填されている。第１流体室2eと第２流体室2fの間で作動流体HFを流動させるための第１連通路10が第１及び第２流体室2e,2fに連通し、第２流体室2fと第３流体室2gの間で作動流体HFを流動させるための第２連通路11が第２及び第３流体室2f,2gに連通し、第１及び第２流体室2e,2fにおける作動流体HFの圧力が流体圧調整装置12で調整される。【選択図】図１
