Claims (1)
キ液圧が個々に制御可能であるとともに、左右後
輪へブレーキ液を供給する管路の中途部に前輪ブ
レーキ液圧に対して後輪ブレーキ液圧を減圧させ
るプロポーシヨニングバルブを装着したブレーキ
液圧制御装置において、 前記プロポーシヨニングバルブの入力側もしく
は出力側に位置する管路に、車速の増大に伴つて
後輪ブレーキ液の液圧を低減させる減圧弁を装着
したことを特徴とするブレーキ液圧制御装置。[Scope of Claim for Utility Model Registration] Brake fluid pressure supplied from the master cylinder to each wheel can be controlled individually, and a pipe that supplies brake fluid to the left and right rear wheels is installed in the middle of the pipe to control front wheel brake fluid pressure. In a brake fluid pressure control device equipped with a proportioning valve that reduces the rear wheel brake fluid pressure as the vehicle speed increases, a conduit located on the input side or output side of the proportioning valve reduces the rear wheel brake fluid pressure as the vehicle speed increases. A brake fluid pressure control device characterized by being equipped with a pressure reducing valve that reduces fluid pressure.
