Electronically regulated brake actuating system for motor vehicles has pressure source with proportional regulating valve that enables pressure produced by pump to be adjusted

摘要

The system has a main brake cylinder (2) with a pressure source (30) with at least one pump (31) controlled by a control unit to apply pressure to wheel brakes that can be connected to the main cylinder via at least one hydraulic connection that can be closed by isolating valves (12). There are a device for detecting a driver deceleration demand and wheel brake inlet and outlet valves. The pressure source has a proportional regulating valve (32) that enables the pressure produced by the pump to be adjusted.
