摘要： A fuel system (24) includes a fuel passage (28) for conveying a hydrocarbon fuel. The hydrocarbon fuel is reactive with oxygen to form carbonaceous deposit. A device is disposed in the fuel passage such as to be exposed to the hydrocarbon fuel. The device includes first and second surfaces that are spaced from each other by a clearance gap into which the hydrocarbon fuel can infiltrate. The first and second surfaces are in sliding motion with respect to each other when the device is in operation. A frangible fluoropolymer coating is disposed on at least one of the first or second surfaces along the clearance gap. The coating is subject to the carbonaceous deposit adhering thereon. The coating is configured to allow portions to release by shearing off with the carbonaceous deposit under stress from the sliding motion to uncover a newly exposed face of the coating.

摘要： A spool and sleeve assembly (38) for a metering valve comprises a spool body (40) defining a center axis, and a sleeve body (42) having a bore (44) that receives the spool body (40). The sleeve body (42) includes at least one metering window (46) open to the bore (44) and is moveable between a metering position to control flow through the metering window (46) and a shutoff position where flow is prevented from exiting an outlet end of the bore (44). A seal assembly reacts between the spool body (40) and the sleeve body (42) to provide at least a first sealing interface (50) and a second sealing interface (52) axially spaced from the first sealing interface when the spool body (40) is in the shutoff position. A metering valve (34) for a fuel system is also disclosed.

摘要： L'invention a trait à une virole composite segmentée de compresseur de turbomachine axiale. Chaque segment 18, 20 est formé par un premier matériau polymère et comprend au moins une surface technique 28 formée d'un deuxième matériau polymère co-injecté avec le premier matériau polymère du segment. La surface technique peut être une surface de contact avec une aube. Dans ce cas, la surface technique présente un profil de lèvre et est en matériau élastomère. La surface technique peut également être la surface intérieure 28 d'accrochage de l'abradable. Dans ce cas, le matériau peut être du silicone afin de favoriser l'accrochage d'abradable à base de silicone. La surface technique peut également être une face latérale avant ou arrière de la virole, cette face étant destinée à entrer en contact avec une surface fixe correspondante. Dans ce cas, le matériau peut comprendre du téflon afin de former une surface technique avec des propriétés de frottement sec.
Les mesures de l'invention permettent de réaliser des fonctions techniques supplémentaires à une virole directement lors du moulage par injection des segments de virole.
