Abstract: A bleed valve includes a housing with an inlet coupled to an outlet by a duct, a guide tube with an orifice fixed in the housing between the inlet and the outlet, a piston, and baffle. The piston is slideably supported on the guide tube and is movable between an open and a closed position, the duct fluidly coupling the inlet and outlet in the open position, the duct fluidly separating the inlet and outlet in the closed position. The orifice fluidly couples the inlet and outlet in the open and closed positions to move piston between the open and closed positions according to differential pressure between the bleed valve inlet and outlet. The baffle is slideably supported by the guide tube to set the differential pressure at which the piston moves between the open and closed positions. Gas turbines and differential pressure adjustment methods are also described.

Abstract: A seal assembly for a creating a seal between a shaft and a valve housing of a bleed valve that impedes contaminants from reaching bearings includes first and second seal pieces. The first seal piece circumferentially surrounds the shaft and is disposed between the shaft and the valve housing. The second seal piece is in contact with and is disposed axially adjacent to the first seal piece relative to the shaft. The second seal piece is biased against the first seal piece.

Abstract: An electronic module assembly includes a circuit card assembly (CCA) with heat generating electronic components. A connector is electrically connected to the heat generating electronic components, wherein the connector is positioned at a connection end of the CCA. A heatsink is mounted to the CCA, connected in thermal communication with the electronic components. An undulating channel feature is defined along a lateral edge of the heatsink relative to the connector. One or more channels of the undulating channel feature are aligned with an insertion axis defined by the connector.
