摘要： A variable geometry turbine includes a fluid space formed by a nozzle mount and a nozzle plate; and a plurality of nozzle vanes arranged in the fluid space at certain intervals in the circumferential direction so as to partition the fluid space. The nozzle vanes are supported by shafts on the nozzle mount, in such a manner as to be capable of turning. The flow rate of the discharged fluid can be adjusted by opening or closing the cross-sectional area of a flow path formed by the adjacent nozzle vanes. The nozzle plate is provided with plate projections protruding toward the nozzle vanes further than, at least, end surfaces of the nozzle vanes, so as to cover the spaces between leading edges of the nozzle vanes and trailing edges of the nozzle vanes adjacent thereto, when the nozzle vanes are at a closed position.

An exhaust-bypass valve (1) of a turbocharger includes a shunting passage (5) that communicates between a passage (3) at the turbine-inlet side and a passage (4) at the turbine-outlet side and a valve flap (6) that opens and closes this shunting passage (5). The valve flap (6) opens and closes to shunt a gas flowing through the passage (3) at the turbine-inlet side into the passage at the turbine-outlet side. The valve flap (6) is rotatably supported at one side thereof serving as a center-of-rotation side, and the other side thereof moves away from or towards the shunting passage (5) to open or close the shunting passage (5). A tapered portion (10) is provided at an edge on the other side. The edge is at least one of an edge of an opening of the shunting passage (5) facing the valve flap (6) and a side surface of the valve flap (6) facing the shunting passage (5).
