コントロールバルブの流入口と液圧ポンプの吐出
口を接続する供給通路中にアキユムレータを介装
してなる車両用動力舵取装置において、前記アキ
ユムレータを迂回するバイパス通路を設けるとと
もに、同バイパス通路と前記供給通路を接続する
接続部に前記コントロールバルブの非作動時及び
緩作動時には前記バイパス通路を閉じまた前記コ
ントロールバルブの急作動に応じて前記バイパス
通路と前記供給通路の開度を制御して前記アキユ
ムレータへの圧液供給を減量制御する制御弁を設
けたことを特徴とする車両用動力舵取装置。 A bypass passage that bypasses the accumulator in a vehicle power steering system in which an accumulator is interposed in a supply passage that connects an inlet of a control valve operated in response to steering wheel operation and an outlet of a hydraulic pump. At the same time, a connecting portion connecting the bypass passage and the supply passage closes the bypass passage when the control valve is not operated or slowly operated, and closes the bypass passage and the supply passage when the control valve is suddenly operated. 1. A power steering system for a vehicle, comprising a control valve that controls the amount of pressure fluid supplied to the accumulator by controlling the opening degree of the accumulator.
