摘要： An annular seal flange (87) is formed at an inner peripheral edge portion of an upstream-side seal ring (83). The seal flange (87) projects in a downstream direction. When seal rings (83, 85) are viewed from radially inside, the seal flange (87) of the upstream-side seal ring (83) is designed to at least partially occlude an end gap (85f) of the downstream-side (the most downstream-side) seal ring (85).

摘要： Variable vane devices (10) containing rotationally-driven translating vane structures (28) are provided, as are methods for fabricating variable vane devices. In one embodiment, the variable vane device includes a flow assembly (12) having a centerline (16), an annular flow passage (20) extending through the flow assembly, cam mechanisms (60, 62), and rotationally-driven translating vane structures coupled to the flow assembly and rotatable relative thereto. The translating vane structures include vane bodies positioned within the annular flow passage and angularly spaced about the centerline. During device operation, the cam mechanisms adjust translational positions of the vane bodies within the annular flow passage in conjunction with rotation of the translating vane structures. By virtue of the translational movement of the translating vane structures, a reduction in the clearances between the vane bodies and neighboring flow assembly surfaces can be realized to reduce end gap leakage and boost device performance.

摘要： An object is to provide a variable-geometry exhaust turbocharger including a variable nozzle mechanism in which nozzle supports may not deform under a high-temperature condition. A variable-geometry exhaust turbocharger (1) includes: a nozzle mount (2); a nozzle support (6) having a first end coupled to a first face (2a) of the nozzle mount; a nozzle plate (4) coupled to the second end of the nozzle support and supported to be separated from the first face (2aa) of the nozzle mount, the nozzle plate having a first face (4a) coupled to the nozzle support and a second face (4b) which is opposite to the first face and which faces an exhaust gas channel (20) through which exhaust gas flows: a plurality of nozzle vanes (8) rotatably supported between the nozzle mount and the nozzle plate; and a variable nozzle mechanism (10) configured to change vane angles of the nozzle vanes to control a flow of the exhaust gas flowing between the nozzle mount and the nozzle plate. The nozzle plate is formed of a material having a smaller linear expansion coefficient than that of a material forming the nozzle mount.

摘要： In some aspects, a compressor system includes a compressor train including two or more compressors connected in series and a control mechanism. The control mechanism is controlled by a performance controller. The performance controller is operable to identify a process variable of the performance controller; receive, on a recurrent basis from a load sharing controller, a setpoint for the process variable of the performance controller; and control the control mechanism based on the setpoint and the process variable of the performance controller. The setpoint is determined dynamically during operation of the two or more compressors by the load sharing controller based on a load sharing parameter associated with the two or more compressors.
