Abstract
(EN)
The present invention relates to a hydraulic control unit (50) that includes a pump (60) for increasing a hydraulic pressure of a brake fluid. The hydraulic control unit (50) according to the present invention includes: a discharge channel (140, 140a, 140b) from which the brake fluid is discharged, the brake fluid being pressurized by the pump (60); a pulsation reducing unit (80) disposed in the middle of the discharge channel (140, 140a, 140b); and a controller (52) controlling the pump (60) and the pulsation reducing unit (80). The pulsation reducing unit (80) includes: a valve housing (81); a fixed core (83) fixed to the valve housing (81); a movable core (84) received in the valve housing (81) in an axially movable manner; a closing member (843) interlocking with the movable core (84) and closing the discharge channel (140, 140a, 140b); a coil disposed in a manner to surround the valve housing (81) and the fixed core (83); and an inflow chamber (88) which is formed by the valve housing (81) and one end surface (844) of the movable core (84), into which the brake fluid from the discharge channel (140a) flows, and whose volume can vary.

La présente invention concerne une unité de commande hydraulique (50) comprenant une pompe (60) destinée à augmenter une pression hydraulique d'un liquide de frein. L'unité de commande hydraulique (50) selon la présente invention comprend : un canal d'évacuation (140, 140a, 140b) duquel le liquide de frein est évacué, ledit liquide de frein étant mis sous pression par la pompe (60); une unité de réduction d'impulsion (80) disposée au milieu du canal d'évacuation (140, 140a, 140b); et une unité de commande (52) commandant la pompe (60) et l'unité de réduction d'impulsion (80). L'unité de réduction d'impulsion (80) comprend : un corps de vanne (81); un noyau fixe (83) qui est fixé au corps de vanne (81); un noyau mobile (84) reçu dans le corps de vanne (81) de façon à pouvoir se déplacer axialement; un élément obturateur (843) coopérant avec le noyau mobile (84) et fermant le canal d'évacuation (140, 140a, 140b); et une bobine qui est disposée de façon à entourer le corps de vanne (81) et le noyau fixe (83); et une chambre d'arrivée de liquide (88) qui est formée par le corps de vanne (81) et une surface d'extrémité (844) du noyau mobile (84), chambre dans laquelle le liquide de frein s'écoule depuis le canal d'évacuation (140a), et qui est de volume variable.
