Title:
VEHICULAR BRAKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/200661
Kind Code:
A1
Abstract:
The present invention comprises a first hydraulic pressure generation unit that generates hydraulic pressure in a wheel cylinder through a first channel, and a valve unit provided in the first channel between the wheel cylinder and the first hydraulic pressure generation unit. The valve unit includes a first solenoid valve and a second solenoid valve. The first solenoid valve includes a first valving element and a first valve seat, and is a normally-open type solenoid valve, wherein the direction proceeding from the wheel cylinder to the first hydraulic pressure generation unit is the same as a first direction in which the first valving element lands on the first valve seat. The second solenoid valve is connected in parallel with the first solenoid valve, includes a second valving element and a second valve seat, and is a solenoid valve, wherein the direction proceeding from the wheel cylinder to the first hydraulic pressure generation unit is the opposite of a second direction in which the second valving element lands on the second valve seat.
