Description
車両ブレーキ装置の部分作動の運転状態または完全作動の運転状態において、ブレーキ圧は外部で駆動される圧力発生器22によって発生される。この圧力発生器22は、ブレーキ液を減衰装置10の減衰室18a内に圧送し、この減衰室18aから圧力媒体が段付きピストン14の絞り通路30を介して減衰室18b内に流入し、この減衰室18bから最後に、接続されたホイールブレーキ26に流入する。圧力発生器22によって生ぜしめられた圧力脈動は、減衰装置10の中空室12内で段付きピストン14を往復移動させ、それによって、ホイールブレーキ26の圧力媒体接続部20cとマスタブレーキシリンダ側の圧力媒体接続部20bとの間の圧力媒体接続部28の流過横断面を変化させ、それと同時に、減衰室18aと減衰室18bとの間の容積比を変化させ、その結果、圧力脈動は減衰装置10によって補正されるか若しくは均される。
