ABSTRACT:
A motor vehicle wheel engages a gear which drives a multistage cam which actuates a system of hydraulic valves and pistons. A pressure-sensitive spool valve detects when the hydraulic pressure in the brake system exceeds the value which causes the wheel to enter the skid mode. The hydraulic pressure from the brake system passes through the pressure-sensitive valve to the system of hydraulic valves and pistons operated by the cam. The outlet of the hydraulic valve and piston system goes to the brake cylinder in the wheel. During the skid mode, a valve in the hydraulic valve and piston system closes and a cam action on one of the pistons in the system causes a pumping pressure to be applied to the brake cylinder. This anti-skid device further includes two fail-safe features to protect against system failure.
