Abstract: A torque transfer assembly includes a drive shaft and a driven shaft. The drive shaft includes a motor shaft configured to be connected to and rotated by a motor, and a cam shaft connected to and rotatable with the motor shaft. The driven shaft is connected to and rotatable with the cam shaft, and the cam shaft is formed of a dielectric material defining an insulating barrier between the drive and the driven shaft.

Abstract: A method and apparatus, for manufacturing a duct for a fluid management system of an aircraft. A filament-fed additive manufacturing apparatus is used to perform the additive manufacturing process. The additive manufacturing apparatus comprises a nozzle, wherein the nozzle receives material in the form of a filament and adds said material to the duct in a location proximate to the nozzle location, and wherein the nozzle moves in a generally helical path relative to the duct.

Abstract: A valve housing for a check valve comprises a housing body defining a valve opening and a first pin extending across the valve opening defining a pin axis (A). The valve housing further comprises a pair of first pin support elements provided on the housing body on opposing sides of the valve opening and extending towards the first pin, the first pin support elements for contacting and supporting an under side of the first pin. The valve housing further comprises a pair of first pin location elements provided on the housing body on opposing sides of the valve opening, each first pin location element comprising a strip element having a mounting portion mounted to the housing body and a locating portion which extends over an upper side of the first pin and around at least an upper circumference thereof to locate the first pin.

Abstract: A valve housing for a check valve comprises a housing body for mounting a pair of flapper elements and a pair of valve openings extending through said valve body. The valve openings are separated by a web which extends from one side of the valve body to an opposed side of the valve body. The valve body and web define sealing surfaces around the valve openings on one face of the valve housing. The web comprises a slot extending into the web from a face thereof on said one face of said valve housing and extending along a length of the web.

Abstract: According to the present disclosure, there is provided a check valve comprising a valve housing defining a pair of valve openings. A pair of flapper elements are pivotably mounted to at least one hinge pin for rotation relative to the housing between an open position in which they permit fluid flow through the respective valve openings and a closed position in which they prevent fluid flow through the valve openings. The check valve also includes at least one hinge pin receiving post that extends upwardly from the valve housing, wherein the at least one hinge pin receiving post comprises a first, lower end portion having an opening for receiving said at least one hinge pin, a second, upper end portion and a flexible, serpentine portion intermediate said end portions.
