Document Type and Number:
Japanese Patent JPS63301155
Kind Code:
A
Abstract:
PURPOSE:To improve a pedal operation feeling by making a constitution so that a liquid quantity supplied from a master cylinder to pressure converter and consumed may dwindle as compared with a consumed liquid quantity supplied to a wheel cylinder via the pressure converter. CONSTITUTION:This actuator A which is to control liquid pressure discharged from a master cylinder 11 and supplied to a wheel cylinder 12 contains the 1st pipe passage 21 connected to the master cylinder 11 and the 2nd pipe passage 22 connected to the wheel cylinder 12. Also, a supply changeover valve 24 controlling connection among a reserver 23 and both pipe passages 21, 22, a discharge changeover valve 25 controlling connection between the 2nd pipe passage 22 and the reserver 23, and an ever-opening cut valve 26 closing the 1st pipe passage 21 at the time of anti-skid control, are equipped. In addition, a pressure converter 27 that is made up by energizing with springs 27c to a smaller diameter side a stepped piston 27b which is in parallel with the cut valve 26 and whose smaller diameter side is on the cylinder side and whose outer form side is on the wheel cylinder side, is connected.
