Title: Innovations of William R. Schipper
Introduction
William R. Schipper is a notable inventor based in Clio, Michigan, recognized for his contributions to automotive technology. He holds 2 patents that showcase his expertise in power steering systems. His work has significantly impacted the efficiency and functionality of steering mechanisms in vehicles.
Latest Patents
One of Schipper's latest patents is a variable effort power steering system designed for automobiles. This innovative system includes a rotary valve power steering gear and a detent type variable effort detent system. The system operates by utilizing fluid detent pressure that is proportional to vehicle speed, which helps to prevent relative angular displacement between the input and output members of the steering gear until a certain threshold of steering effort is exceeded. Additionally, a shunt system is incorporated, which progressively opens as vehicle speed increases, allowing for a more linear increase in steering assist boost pressure relative to handwheel effort.
Another significant patent by Schipper is a speed-sensitive detent system for a variable effort power steering gear. This system features a detent support portion on the output member of the steering gear, which contains multiple internally threaded radial insert bores. Each detent insert is designed to accommodate a detent ball that is biased by servo fluid pressure into a detent groove, ensuring that the hydraulic balance of the rotary valve is maintained during operation.
