Abstract: A turbine (10) for a charging device (1) with a turbine housing (100) with a feed duct assembly (200), a turbine outlet duct (110) and a receptacle space (120). The feed duct assembly (200) includes a first feed duct (210) having a first fluid inlet portion (211) and a first fluid outlet portion (212), and a second feed duct (220) having a second fluid inlet portion (221) and a second fluid outlet portion (222). The first fluid outlet portion (212) extends across a first angular range (α1) about the guide installation (400). The second fluid outlet portion (222) extends across a second angular range (α2) about the guide installation (400). The first angular range (α1) is larger than the second angular range (α2). The first fluid inlet portion (211) and the second fluid inlet portion (221) are mutually spaced apart in the circumferential direction (26).

Abstract: A gas turbine engine including a core having in serial flow order a compressor, a combustor, and a turbine—the compressor, combustor, and turbine together defining a core air flowpath. The gas turbine engine additionally includes a fan section mechanically coupled to the core, the fan section including a plurality of fan blades, and each of the plurality fan blades defining a pitch axis. An actuation device is operable with the plurality fan blades for rotating the plurality fan blades about their respective pitch axes, the actuation device including an actuator located outward of the core air flowpath to, e.g., simplify the gas turbine engine.

Abstract: Guide vane adjusting device for a flow machine to rotate guide vanes, with a driveshaft, and a control ring that transmits rotation of the driveshaft to rotate the guide vanes. The driveshaft is directly coupled with one of the guide vanes to be directly rotatable by the driveshaft without the intermediary of the control ring. The directly driven guide vane is articulately coupled with the control ring via a transmission lever. The other guide vanes are indirectly rotatable with the intermediary of the control ring. The control ring is displaceable in circumferential and axial direction such that forces at coupling points between the control ring and the transmission levers coupled with the control ring run perpendicular to the transmission levers.

Abstract: A turbocharger includes a turbine housing that defines a flow passage for a fluid. The turbine housing includes a turbine shroud member. The turbocharger also includes a turbine wheel supported for rotation within the turbine housing relative to the turbine shroud member. The turbine wheel is configured to rotate as the fluid flows through the flow passage. Moreover, the turbocharger includes a port extending through the turbine shroud member. The port is configured to receive a portion of the fluid flowing through the flow passage.

Abstract: A feedback sensor system is provided. The feedback sensor system includes a first ring rotatable about an axial direction and a second ring also rotatable about the axial direction. The first ring includes one or more first ring features and the second ring includes one or more second ring features. The feedback sensor system also includes a sensor directed at the surface of the first ring for sensing a parameter influenced by the one or more first ring features and the one or more second ring features. The sensor may determine a position of the first ring relative to the second ring by sensing the parameter.
