FLUID DAMPER
PROBLEM TO BE SOLVED: To provide a fluid damper capable of easily implementing assembly work and obtaining a relatively great damping force by reducing conventional partition walls for dividing a fluid chamber filled with a working fluid.SOLUTION: First and second pistons that are linked with each other while interposing an interval in an axial direction therebetween are freely movable in the axial direction inside of a cylinder. Inside of the cylinder, at least a first fluid chamber that is separated by the first piston, a second fluid chamber that is separated by the first and second pistons and a third fluid chamber that is separated by the second piston are provided and the first to third fluid chambers are filled with working fluids. A first communication path for causing the working fluid to flow between the first fluid chamber and the second fluid chamber is communicated to the first and second fluid chambers, and a second communication path for causing the working fluid to flow between the second fluid chamber and the third fluid chamber is communicated to the second and third fluid chambers.SELECTED DRAWING: Figure 1
【課題】作動流体が充填される流体室を区画するための従来の仕切壁を削減でき、それにより組立て作業を容易に行うことができるとともに、比較的大きな減衰力を得ることができる流体ダンパを提供する。【解決手段】互いに軸線方向に間隔を存した状態で連結された第１及び第２ピストンが、シリンダ内を軸線方向に移動自在である。シリンダ内には、第１ピストンで区画された第１流体室と、第１及び第２ピストンで区画された第２流体室と、第２ピストンで区画された第３流体室とが少なくとも設けられ、第１〜第３流体室には、作動流体が充填されている。第１流体室と第２流体室の間で作動流体を流動させるための第１連通路が第１及び第２流体室に連通し、第２流体室と第３流体室の間で作動流体を流動させるための第２連通路が第２及び第３流体室に連通している。【選択図】図１
