HYDRAULIC PRESSURE CONTROL DEVICE

To provide a hydraulic pressure control device which can stably reduce the pulsation of a desired frequency, and can suppress the size enlargement of the device.SOLUTION: A hydraulic control device 1 comprises: a fluid supply part 2 for discharging fluid from a discharge port 2a; a first liquid path 3 for connecting the discharge port 2a and a fluid supply object 9, and zoned by a first peripheral wall part 80; a dead-end second liquid path 4 branched from the first liquid path 3 so as to form a side-branch type damper; and a cylindrical or bottomed cylindrical sleeve member 5 arranged in the second liquid path 4 so that an external peripheral face 51 abuts on a second peripheral wall part 81 which defines the second liquid path 4, forming a sleeve liquid path 52 in which the fluid can circulate while communicating with the first liquid path 3 at a center portion, and constituted so that a Young's modulus becomes lower than that of the first peripheral wall part 80.SELECTED DRAWING: Figure 1 【課題】所望の周波数の脈動を安定して低減させることができ、且つ装置の大型化の抑制が可能な液圧制御装置を提供する。【解決手段】本発明の液圧制御装置１は、吐出口２ａからフルードを吐出するフルード供給部２と、吐出口２ａとフルード供給対象物９とを接続し第１周壁部８０にて区画された第１液路３と、サイドブランチ型ダンパを形成するように第１液路３から分岐した袋小路の第２液路４と、第２液路４を区画する第２周壁部８１に外周面５１が当接するように第２液路４内に配置され、中央部分に第１液路３に連通してフルードが流通可能なスリーブ液路５２を形成し、且つヤング率が第１周壁部８０よりも低くなるように構成された筒状又は有底筒状のスリーブ部材５と、を備える。【選択図】図１
