Abstract
A rotary valve for use in a steering control of an integrated brake and steering system. The rotary valve has a pinion with a first end fixed to a housing and a second end to which a lever arrangement is attached. The pinion has a series of grooves located on its surface and whenever the lever arrangement is moved, the grooves control the flow of fluid to a piston. Thereafter, movement of the piston by the fluid creates a rotary torque that is supplied to a steering gear to aid in the operation of the steering system.
