Abstract
An improvement to a priority valve which provides priority flow to a priority function, not only directly from a fluid power source, but also from an accumulator when the priority demand exceeds the output of the fluid power source. This priority flow valve also provides flow to one or more secondary functions when the priority flow requirements are satisfied or when the priority flow path is blocked.
