Summary:A system for supplying pressurized fluid to a combustor (100) of a gas turbine is disclosed. The system may include an end cover (110) and a fuel nozzle (112) extending from the end cover (110). The fuel nozzle (112) may include a downstream end. Additionally, the system may include a cap assembly (104) configured to receive at least a portion of the fuel nozzle (112). The cap assembly (104) may include an upstream wall (130) spaced apart from the downstream end, a downstream wall (132) disposed proximate to the downstream end and a cap chamber (134) defined between the upstream and downstream walls (130,132). Moreover, a conduit (102) may extend through the end cover (110) and the upstream wall (132) such that a discharge end (152) of the conduit (102) is in flow communication with the cap chamber (134).
