Proportioning Valve to Skid Control - A Logical Progression

This paper discusses the development of a family of brake control devices capable of handling all vehicles from passenger cars through air-braked heavy trucks. These devices consist of: Hydraulic load-sensitive proportioning valves for passenger cars, light trucks, and vans; hydraulic load-sensitive proportioning valves for medium trucks; pneumatic load-sensitive proportioning valves for air-braked heavy trucks and tractor/trailer combinations; skid control systems for passenger cars; and skid control systems for trucks and tractor/trailer vehicles.

The paper explains how this broad approach to brake controls allows the selection of a system which can be tailored to the particular brake control needs of a specific vehicle and its duty cycle. Except for the passenger car skid control, these devices are capable of being retro-fitted on existing vehicles.
