Fluid system with signal-mimicking device and associated method

A fluid system, comprising:

• 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.

A steering system, comprising:

• a joystick steering control valve,
• an orbital steering control valve,
• a priority valve biased to preferentially supply pressurized fluid to both the joystick steering control valve and the orbital steering control valve, and
• a signal-mimicking valve fluidly coupled to a static LS port of the joystick steering control valve, a dynamic LS port of the orbital steering control valve, and a dynamic LS pilot port of the priority valve for mimicking a static LS signal from the static LS port of the joystick steering control valve into a dynamic LS signal from the dynamic LS port of the orbital steering control valve to produce a combined LS signal communicated to the dynamic LS pilot port of the priority valve.
