Abstract
A hydraulic braking system for an automotive vehicle having a master cylinder communicated with a wheel brake cylinder through a primary passage, and an anti-skid apparatus including a fluid pump which is disposed in a recirculation passage connected to the primary passage. An orifice is disposed in the recirculation passage on a discharge side of said fluid pump. In parallel with the orifice, a relief valve is disposed. The relief valve permits a flow of a brake fluid from the fluid pump to the primary passage when a differential pressure between the pressures on the upstream side and downstream side of the orifice exceeds a predetermined value. Consequently, a discharge pulsation of the fluid pump is effectively reduced.
