Abstract
A pressure fueling adapter for aircraft has spring loaded primary and secondary nested poppets for controlling fluid flow therethrough, the primary poppet operable by engagement with the position lever of a fuel nozzle and the secondary poppet responsive to pressure differentials to allow inlet fluid flow and check back flow. A cam interengagement mechanism may be manually actuated to connect the primary and secondary poppets for simultaneous movement by the position lever of the fuel nozzle to defeat the secondary poppet check, for defueling purposes.
