  • Purge ejector assembly for an engine
    Patent number: 10557442
    Abstract: A purge ejector assembly for an engine has a first fluid passage with a nozzle device therein that raises flow velocity of air and a first valve therein between an engine manifold port and the nozzle and permitting flow from the engine manifold port toward the nozzle device while restricting reverse flow. A second fluid passage has a second valve therein between the engine manifold port and a purge flow port, and permitting flow from the purge flow port toward the engine manifold port while restricting reverse flow. A third fluid passage extends from a second passage position located between the purge flow port and the second valve to a first passage position located between the nozzle device and an air inlet channel port. A third valve in the third passage permits flow from the purge flow port toward the air inlet channel port, while restricting reverse flow.
