Abstract
An anti-skid device for motor vehicles provided with a hydraulic circuit for connecting the brake master cylinder with the wheelbrake cylinder has a first valve for dividing the hydraulic circuit into two sections, a second valve for supplying the hydraulic pressure to the pressure reducing piston and a third valve having two valve sections for controlling the hydraulic pressure supplied to a working fluid chamber so as to prevent it from exceeding a predetermined degree. The third valve is constructed so that a fluid chamber defined by both the slidable valve members and fixed valve members of the two valve sections is formed therein so as to be communicated with the working fluid chamber side circuit through an orifice, in order to prevent the generation of strange sounds from the third valve during its operation by damper action of the fluid chamber.
