Abstract
A vehicle anti-skid braking device has a housing, a first normally open valve disposed in the housing for controlling fluid flow through a first passage which is connected to a master cylinder and to a brake cylinder of a wheel of the vehicle, a second passage formed in the housing for receiving hydraulic fluid from a pump driven by the rotational force of the wheel, a first piston slidably disposed in a bore for actuating the first valve, a second piston slidably disposed in the second passage for cooperating with the first piston so as to cut off the major portion of hydraulic fluid supplied from the pump, and a third valve disposed in a third passage parallel with respect to the second passage for controlling the remaining portion of hydraulic fluid flow.
