Abstract
An anti-skid apparatus in a vehicle braking system including a bypass circuit connected in parallel with a braking circuit between a master cylinder and a wheel brake cylinder, wherein a fluid pump is disposed within the bypass circuit and connected to a fluid reservoir to produce a hydraulic power pressure, a first switchover valve is disposed within both the circuits to permit the flow of fluid passing through the braking circuit in its deactivated condition and to interrupt the braking circuit and connect the brake cylinder to the reservoir through the bypass circuit in its activated condition, a second switchover valve is disposed between the master cylinder and the first switchover valve to permit the flow of fluid passing through the braking circuit while the first switchover valve is maintained in its deactivated conidition and to interrupt the braking circuit and connect the pump to the brake cylinder in response to a decrease of the brake cylinder pressure caused by activation of the first switchover valve, a regulator valve is disposed within the bypass circuit between the pump and the second switchover valve to control the power pressure in dependence upon the master cyl…
