Abstract
Conventional accumulator charging valves operate automatically and reliably in constant flow industrial hydraulic systems. By contrast, these valves do not necessarily perform reliably in variable flow mobile hydraulic systems because the accumulator circuit charging pump flow changes with the engine speed. Occasionally, the valve sticks in a transitional condition which neither allows the accumulator to fully charge nor lets the charge pump unload.
This paper describes the operation of conventional and mobile type accumulator charging valves and describes how the spool design pilot circuit valve improves the reliability of the mobile machine accumulator charging valve.
