Abstract
A full fluid-linked steering system includes a fluid pump ( ), a fluid controller ( ), a steering actuator ( ), an electro-hydraulic compensation valve ( ), and a vehicle microprocessor ( ). Downstream of the fluid pump ( ) is a load sensing priority flow control valve ( ) having both a controlled flow outlet port (CF) and an excess flow outlet port (EF). The excess flow outlet port (EF) communicates with an inlet port ( ) of the fluid controller ( ), while the controlled flow outlet port (CF) communicates with a fluid inlet ( ) of the compensation valve ( ). As a result, when the steering actuator ( ) is at the end of its travel, pressure will be communicated only through the compensation valve ( ), and the operator will be unable to turn the steering wheel further in the same direction.
