Abstract: A gas lift valve assembly includes a housing and a check valve. The housing defines an inlet port and an outlet port, and includes an inner casing having a radial outer surface and a radial inner surface at least partially defining a main flow passage. The check valve includes a sealing mechanism disposed around the radial outer surface of the inner casing, and a valve member including an outwardly extending sealing segment. The valve member is moveable between an open position and a closed position in which the sealing segment sealingly engages the sealing mechanism.

Abstract: A gas lift valve assembly includes a housing, a check valve, and a fluid flow barrier. The housing defines an inlet port, an outlet port, and a main flow passage providing fluid communication between the inlet port and the outlet port. The main flow passage has an upstream end and a downstream end. The check valve includes a sealing element disposed at the downstream end of the main flow passage, and a valve member configured to sealingly engage the sealing element. The valve member is movable between an open position in which fluid flow is permitted in a downstream direction, and a closed position in which the valve member inhibits fluid flow in an upstream direction. The fluid flow barrier is disposed within the main flow passage, and is configured to direct fluid flow away from the sealing element when the valve member is in the open position.

Abstract: The invention relates to a gas turbine engine comprising a casing having a compressor section, combustion section and turbine section, axially arranged in a flow direction about a rotational axis of the engine. The engine includes a rotor located within the casing and rotatable about the rotational axis, including multiple sets of circumferentially arranged blades, with at least one set corresponding to the compressor section and another set corresponding to the turbine section. The engine also includes a set of vanes circumferentially arranged about the rotational axis and at a location upstream of the combustion section, with the vanes having a pressure side and a suction side. The engine further includes a cooling conduit extending from upstream of the combustion section to downstream of the combustion section, with an inlet located on the suction side of at least one of the vanes which allows cooling air to enter the inlet and is directed through the cooling conduit for cooling.
