Motor vehicle braking control system

摘要

The system has a brake fluid pressure modulator (MD) between the main cylinder (MC) and the wheel brake cylinder, a pump (HP) delivering fluid to the modulator under pressure and a container for storing fluid let out of the wheel cylinder by the modulator. A first valve normally connects the main cylinder to the modulator. A second valve normally blocks the connection between the main cylinder and pump inlet. A non-return valve enables fluid to flow to the pump and prevents reverse flow. A regulator actuates the pump in continuous drive if it is regulating the modulator and actuates the second valve to connect the main cylinder to the pump if the braking pressure in the wheel cylinder is increased by the modulator.
