Abstract: A hydraulic flow amplifier valve assembly for regulating fluid flow to steering jacks. A steering control valve receives fluid directly from a pump and is pilot operated by fluid from a conventional metering unit to provide amplified flow of pump fluid to the jacks. A blocker valve passes fluid from the steering valve during steering motion of the jacks and otherwise isolates the jacks to prevent fluid loss. A lock valve protects against steering wheel slippage during overpressure conditions and also permits pilot fluid provided by the metering unit to operate the steering jacks in the event of pressure failure.

Abstract: There is disclosed means to provide a supplemental supply of fluid under pressure for emergency use in the hydraulic system of a vehicle with a normal supply provided by an engine driven pump. Pressure for the supplemental system is provided by a simple system including wheel driven pump which is operative during forward movement of the vehicle thereby insuring hydraulic control in emergency situations such as engine and/or engine driven pump failure. During reverse movement of the vehicle, simple pressure valves prevent flow from the main system into the supplemental system but allow reverse circulation of fluid through the wheel driven pump, thereby preventing cavitation.
