ALEXANDRIA, Va., July 21 -- United States Patent no. 12,687,156, issued on July 21, was assigned to The Boeing Co. (Arlington, Va.).

"Accumulator for prevention of hydraulic pump cavitation" was invented by Barry Allan Wilson (Edmond, Okla.).

According to the abstract* released by the U.S. Patent & Trademark Office: "To prevent cavitation damage to a hydraulic fluid pump, a low pressure accumulator is fluidly connected to the suction line of an engine-driven hydraulic pump to boost suction line pressures during instantaneous demands for higher pump flows. The accumulator acts as a localized reservoir for the engine-driven pump to avoid deleterious pressure drops which give rise to pump cavitation. In one disclosed architectural arrangemen...
