Title:
FLUID PRESSURE CONTROL UNIT OF BRAKE SYSTEM FOR VEHICLE
Document Type and Number:
Japanese Patent JP2020203526
Kind Code:
A
Abstract:
To provide a brake fluid pressure control device which enables a brake fluid to flow bypassing a damper which absorbs pulsation according to a vehicle brake force required.SOLUTION: A brake fluid pressure control device (20) according to the invention includes: a discharge duct line (38) to which a brake fluid boosted by a pump (45) is discharged; a damper (27) into which the brake fluid flows from the discharge duct line (38); and a bypass valve (39) which guides the brake fluid so that the brake fluid selectively flows through one of a damper duct line (36) into which the brake fluid flowing into the damper (27) flows and a bypass duct line (37) which bypasses the damper (27). The bypass valve (39) includes a piston (391) having a damper duct line opening (393) leading to the damper duct line (36) and a bypass duct line opening (394) leading to the bypass duct line (37).SELECTED DRAWING: Figure 3
