摘要： A bypass turbine engine is described. The engine includes a system for bleeding gas from a primary stream to a secondary stream. The system may include two coaxial rings extending one around the other. A perforated internal first ring may be situated at the level of an outer casing and may extend substantially in a continuation of the outer casing. A perforated external second ring may be mounted such that it slides circumferentially on the first ring between a first position in which the perforations of the rings do not communicate with one another and a second bleed position in which the perforations of the rings communicate with one another.

摘要： A turbomachinery component of a gas turbine engine is disclosed having a number of techniques of reducing the effects of a gap flow between an airfoil member of the gas turbine engine and a wall of the gas turbine engine. The airfoil member can be variable and in one form is a variable turbine vane. In one embodiment a brush seal is included between the vane and the wall. In another form a wear surface is disposed between the vane and the wall. In yet another form a moveable member capable of being actuated to change position can be disposed between the vane and the wall to alter the size of a gap between the two.

摘要： A turbocharger includes: a turbine housing including an internal space formed therein; a bearing portion provided in the turbine housing; a shaft rotatably inserted into a bearing hole in a state where at least one end protrudes more to an inside of the turbine housing than the bearing portion; and a valve fixed to the shaft and configured to open and close a flow path opened to the internal space. The bearing portion includes a protrusion portion which protrudes from an inner wall of the turbine housing. The radial hole of the protrusion portion penetrates the bearing portion in a radial direction of the shaft, from the outer circumferential surface of the bearing portion to the bearing hole.
