Claims (1)
シング内に大径部と小径部とを有する段付ピスト
ンを摺動自在に嵌合し、この段付ピストンを一方
向に付勢して通常は非作動位置に保持させ、また
上記段付ピストンの一端小径部と他端大径部とに
それぞれブレーキ液圧を作用させてその受圧面積
差で段付ピストンを上記非作動位置から上記付勢
方向と逆方向に変位させ、かつ上記段付ピストン
の大径部側のブレーキ液通路から小径部側のブレ
ーキ液通路へのブレーキ液の流通を許容する逆止
弁を、上記段付ピストンが非作動位置に位置した
際に開放状態に維持させるようにしたブレーキ液
圧制御弁において、上記ケーシングをマスターシ
リンダのハウジングに多孔質ガスケツトを介して
取付けたことを特徴とするブレーキ液圧制御弁。 A stepped piston having a large diameter portion and a small diameter portion is slidably fitted into a casing attached to the master cylinder housing, and this stepped piston is normally held in a non-operating position by biasing it in one direction. In addition, brake fluid pressure is applied to the small diameter portion at one end of the stepped piston and the large diameter portion at the other end, and the stepped piston is displaced from the non-operating position in a direction opposite to the urging direction by the difference in pressure receiving area. and a check valve that allows the flow of brake fluid from the brake fluid passage on the large diameter side of the stepped piston to the brake fluid passage on the small diameter side when the stepped piston is in a non-operating position. 1. A brake fluid pressure control valve configured to be maintained in an open state at all times, wherein the casing is attached to a housing of a master cylinder via a porous gasket.
