Hydraulic braking system for a vehicle

摘要

A hydraulic braking system for a vehicle having a wheel includes a wheel brake cylinder operatively connected to the wheel for applying braking force to the wheel, and a master cylinder for generating hydraulic pressure in response to depression of a brake pedal and for supplying the hydraulic pressure to the wheel brake cylinder. The master cylinder is connected to the wheel brake cylinder via a first conduit. The wheel brake cylinder is connected to a reservoir for storing brake fluid via a second conduit. A normally closed solenoid valve is disposed in the second conduit. A hydraulic pressure pump is disposed in the first conduit and includes an inlet connected to the master cylinder and an outlet connected to the wheel brake cylinder. A third conduit connects the second conduit at a point between the normally closed solenoid valve and the reservoir to the first conduit at a point between the inlet of the hydraulic pressure pump and the master cylinder.
