Abstract

This invention relates to a hydraulic pressure control valve arrangement for automotive vehicle wheel brake systems, the latter system comprising a hydraulic master cylinder to be actuated by operating a foot brake pedal, a hydraulic brake pressure control valve assembly provided with a pneumatic servo piston mechanism, and an electromagnetic change-over valve assembly fluidically connected therewith, a skid sensor operatively connected therewith and also with a vehicle wheel, a wheel cylinder mechanism for applying hydraulic braking effort upon vehicle wheels and includes the provision for an inertia responsive valve for additionally controlling the braking fluid pressure reapplication in the wheel cylinders so as to have that reapplication be rapid at first to the fullest extent in accordance with the road coefficient and then becomes gradual.
