Claims (1)
- 流体が封入されたシリンダと、該シリンダ内に摺動可能に嵌装されたピストンと、一端が前記ピストンに連結され、他端が前記シリンダの外部へ延出されたピストンロッドと、前記シリンダ内のピストンの摺動によって流体が流通する通路と、前記通路の下流側に環状に設けられた弁座と、前記弁座に離着座すると共に前記通路の流体の流れを制御して減衰力を発生させる複数のディスクバルブとを備えた流体圧緩衝器において、
前記複数のディスクバルブの前記通路側には、前記弁座の径寸法よりも小径で、前記ディスクバルブが開弁するまで開弁方向に前記ディスクバルブを付勢する付勢部材を設けたことを特徴とする流体圧緩衝器。
