Hydraulic control device for a brake master cylinder

摘要

The system has a hydraulic or pneumatic brake assistance servomotor (90) activated by a control component (1) i.e. brake pedal. The servomotor is hydraulically coupled to a master brake cylinder (5), and is not mechanically coupled to a primary piston (50) of the master brake cylinder. An auxiliary pressure device (2) is controlled by the control component, and controls the servomotor. The pressure device has a piston (21) that slides in an enclosure (20) under the control of the control component. The servomotor and the cylinder are made as a single part.
