Claims

[Claims for Utility Model Registration] A supply passage that communicates the master cylinder and the wheel cylinder, and a sump device that is provided in this supply passage and is activated by the skid of the wheel during braking to send the brake fluid supplied to the wheel cylinder to the sump device. A flow path switching valve for discharging brake fluid, a flow rate adjustment valve disposed in a supply passage upstream of the flow passage switching valve, and a flow rate adjustment valve disposed in a supply passage upstream of the flow rate adjustment valve for discharging brake fluid stored in the sump device. and a pump for pressurizing and refluxing the flow, the flow rate regulating valve forming a part of the supply passage and connecting a first passage and a second passage arranged in parallel to each other.
a passageway, and a mechanism for closing the first passageway when a pressure difference between a supply passageway on the upstream side of the flow rate adjustment valve and a supply passageway on the downstream side of the flow path switching valve exceeds a predetermined value; In an anti-skid device comprising an open poppet valve and an orifice disposed in the second passage, the valve body of the poppet valve receives dynamic pressure of brake fluid from the upstream side of the poppet valve during braking. A flow rate adjustment for an anti-skid device, characterized in that a pressure receiving section is formed, and a supply passage on the upstream side of the poppet valve is formed such that the dynamic pressure acts on the pressure receiving section in a direction to open the poppet valve. valve.
