ABSTRACT:
A load-responsive pressure reducing valve assembly for hydraulic brake systems to be interposed between a brake master cylinder and the rear wheel brake cylinders of a wheeled vehicle and includes a fluid pressure proportioning valve which restricts the flow of fluid from the master cylinder to the brake slave cylinder during a predetermined range of increasing fluid pressure supplied therefrom to the brake slave cylinder. The assembly also incorporates an inertia-responsive valve which includes a valve member usually in the form of a ball which is responsive to a predetermined rate of deceleration so as to vary fluid pressure acting on the aforesaid proportioning valve to thereby correspondingly vary or set the reduction starting pressure of the fluid pressure proportioning valve. A preloaded piston is displaceable with the application thereto of a predetermined range of increasing fluid pressure from the master cylinder to correspondingly increase the distance which the ball valve member must travel up an incline to close the inertia-responsive valve and thereby regulate the reduction starting pressure of the reducing valve in correspondence with the distance which the inertia ball, which detects deceleration, travels and the master cylinder hydraulic pressure.
