摘要:
A valve flange joint includes a valve flange and first and second duct flanges. The first and second duct flanges include respective first and second mating portions. The first mating portion includes a first duct rim, a first duct face in contact with a first face of the valve flange, and a first slot. The second mating portion includes a second duct face in contact with a second face of the valve flange, and a second rim. In an embodiment, the valve flange includes a tab that extends in an axial direction through the first slot and includes an inner surface radially inward of an outermost portion of the second mating portion. In another embodiment, a first thickness is defined between the first flange face and the second flange face. Second and third thicknesses are also defined for the first and second mating portions. The three thicknesses are substantially similar.

A check valve is provided and includes a body including a seat, a hinge bifurcating the seat to define openings and a housing coupled to the hinge and a self-trapping insert of compliant material. The self-trapping insert includes an end portion and is securable in the housing such that the end portion protrudes from a side of the housing to contact with a corresponding check valve flapper in a respective open position.

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.

An assembly includes a circuit card assembly (CCA) module including a CCA with heat generating electronic components and a connector electrically connected to the heat generating electronic components. A chassis including an electrical interface is included. The connector of the CCA module is electrically connected to the electrical interface. The chassis includes a removable cover. A heat transfer element is included between the cover of the chassis and an edge of the CCA module for heat sinking heat from the heat generating electronic components through the heat transfer element to the cover of the chassis.

A valve assembly includes a piston housing inside a flow duct between an inlet and an outlet so as to form an annular flow passage between the flow duct and the piston housing. The piston housing is axially aligned with a center axis of the flow duct. A piston is inside the piston housing and is configured to extend downstream of the piston housing in a closed position. A spring biases the piston to the open position. A fluid chamber is between the piston and an upstream end of the piston housing. A control opening extends through the upstream end of the piston housing and fluidically communicates with the flow duct and the fluid chamber. A control piston and a control spring are inside the piston housing. The control spring biases the control piston toward a first position that obstructs the control opening.

A piston assembly includes a piston with a first cap disposed on a first end of the piston and a second cap disposed on a second end of the piston. A piston cross-member is in between the first cap and the second cap. A cover is formed with the piston cross-member and extends between the first cap and second cap.

A bleed valve system includes a bleed valve, a valve regulator, a valve actuator and a reverse flow relief valve. The bleed valve is opened and closed to control a flow of bleed air from an upstream inlet to a downstream outlet. The valve regulator provides a servo pressure used to regulate the position of the bleed valve, and the valve actuator is mechanically connected to open/close the bleed valve based on the servo pressure provided by the valve regulator. The reverse flow relief valve compares a pressure upstream of the bleed valve to a pressure downstream of the bleed valve and in response to the downstream pressure exceeding the upstream pressure creates a fluid communication path between the servo pressure and an ambient pressure to decrease the servo pressure such that the bleed valve is closed.

A valve flange joint includes a valve flange and first and second duct flanges. The first and second duct flanges include respective first and second mating portions. The first mating portion includes a first duct rim, a first duct face in contact with a first face of the valve flange, and a first slot. The second mating portion includes a second duct face in contact with a second face of the valve flange, and a second rim. In an embodiment, the valve flange includes a tab that extends in an axial direction through the first slot and includes an inner surface radially inward of an outermost portion of the second mating portion. In another embodiment, a first thickness is defined between the first flange face and the second flange face. Second and third thicknesses are also defined for the first and second mating portions. The three thicknesses are substantially similar.
