Patent ID: 8522554

Claim:
A fuel nozzle for a turbine engine, comprising: an elongated housing having a central longitudinal axis; at least one fuel delivery passageway that extends down at least a portion of the housing; an active purge air passageway that extends down the housing and that delivers purge air to at least one active purge air discharge opening that is located at the discharge end of the nozzle; and a passive purge air passageway having an inlet that admits air from a position outside the nozzle and adjacent an upstream end of the housing, and having an outlet that is located at the discharge end of the nozzle, wherein the inlet of the passive purge air passageway comprises: a first transfer passageway that extends radially through the nozzle from an upstream end of the passive purge air passageway; and a second transfer passageway that extends from an outward end of the first transfer passageway toward the discharge end of the nozzle in a direction that is substantially parallel to the central longitudinal axis of the housing such that air traveling through the second transfer passageway and into the passive purge air passageway travels in an upstream direction.
