Claims (1)
前記ピストンに結合されるピストンロツドに前記
２つの液室を連通するバイパスを形成する一方、
該バイパスを流れる液体量を変えるべく前記ピス
トンロツドに弁体を配置した液圧緩衝器であつて
、前記弁体は、口径の異なる複数のオリフイスと
、複数のオリフイスのうち最も小さい口径のもの
に連通する緩衝通路とを有し、該緩衝通路は当該
オリフイスを前記バイパスに連通しようとする前
記弁体の動きに伴い流路面積が変化するように形
成された、液圧緩衝器。 The inside of the tube is divided into two liquid chambers by a piston,
forming a bypass communicating the two liquid chambers in a piston rod coupled to the piston;
A hydraulic shock absorber including a valve body disposed on the piston rod to change the amount of liquid flowing through the bypass, the valve body communicating with a plurality of orifices having different diameters and the smallest diameter of the plurality of orifices. and a buffer passage, the buffer passage being formed so that its flow area changes with the movement of the valve body that attempts to communicate the orifice with the bypass.
