To provide a hydraulic control unit equipped with a pump for increasing pressure of brake fluid.SOLUTION: A hydraulic control unit includes: a discharge flow channel through which brake fluid whose pressure is increased by a pump is discharged; a pulsation reducing device arranged in the middle of the discharge flow channel; and a controller for controlling the pump and the pulsation reducing device. The pulsation reduction device includes: a valve housing; a fixed core fixed to the valve housing; a movable core received in the valve housing so as to move in an axial direction; a valve closing body for closing the discharge flow channel by interlocking with the movable core; a coil arranged so as to surround the valve housing and the fixed core; and an inflow chamber formed of the valve housing and one end surface of the movable core in which the volume of brake fluid flowing in from the discharge flow channel is variable.SELECTED DRAWING: Figure 3

    【課題】ブレーキ液の液圧を上昇させるポンプを備えた液圧制御ユニットに関する。【解決手段】本発明に係る液圧制御ユニットは、ポンプによって昇圧されるブレーキ液が吐出する吐出流路と、吐出流路の途中に配置される脈動低減装置と、ポンプと脈動低減装置を制御する制御器とを備え、脈動低減装置は、弁ハウジングと、弁ハウジングに固定される固定コアと、弁ハウジングに軸方向で移動可能に受容される可動コアと、可動コアと連動し、吐出流路を閉鎖する弁閉鎖体と、弁ハウジングと前記固定コアを取り囲むように配置されるコイルと、弁ハウジングと可動コアの一方の端面とにより形成され、吐出流路からのブレーキ液が流入する容積が可変な流入室と、を備える。【選択図】 図3
