ABSTRACT:
An integrated control mechanism for regulating the communication of pressurized fluid from a source to a brake system and a steering system of a vehicle in response to independent operator brake and steering signals. The integrated control mechanism has a housing with a bore therein connected to a single source of fluid under pressure. A rotary valve located in the bore is rotated in response to an operator steering signal to control the communication of the pressurized fluid to the steering system from the bore and thereby provide a power assist in steering the vehicle. A spool valve, concentrically located in said bore with respect to said rotary valve, linearly moves in response to an operator braking signal to control the communication of the pressurized fluid from the bore to the brake system and thereby provide a power assist in effecting a brake application.
