  • Fluid system with signal-mimicking device and associated method
    Patent number: 7451686
    Abstract: A fluid system comprises a static LS valve, a dynamic LS valve, a priority valve biased to preferentially supply pressurized fluid to both the static LS valve and the dynamic LS valve, and a signal-mimicking device fluidly coupled to a static LS port of the static LS valve, a dynamic LS port of the dynamic LS valve, and a dynamic LS pilot port of the priority valve for mimicking a static LS signal from the static LS port of the static LS valve into a dynamic LS signal from the dynamic LS port of the dynamic LS valve to produce a combined LS signal communicated to the dynamic LS pilot port of the priority valve. Such a fluid system may be applied to a steering system. An associated method is disclosed.
