ANTILOCK HYDRAULIC BRAKING SYSTEM

摘要

The pressure in the wheel brakes can be controlled in function of its variation during rotation by means of an inlet valve (15) and an outlet valve (17). Hydraulic fluid delivered by the pumps (13) enters the wheel brake (50) through the inlet valve (15) and leaves through the outlet valve (17). The valves (15, 17) are electromagnetically actuated seat valves which generate considerable control noise. Insertion of a pressure differential limiter (18) upstream of the inlet valve (15) can substantially reduce the generation of noise at least by this valve (15). It has also been found that the control performance can thus be improved.
