Abstract
This relates to a nozzle blade in which the leading edge shape has a curved-line shape that is formed by the distance from the rotation axis of the nozzle blade to the leading edge changing depending on the nozzle blade height position, and the trailing edge shape has a straight-line shape that is formed by the distance from the rotation axis of the nozzle blade to the trailing edge being constant irrespective of the nozzle blade height position.
Claims3
A nozzle blade that is disposed in a plurality in a rotatable manner at the periphery of a turbine impeller that a variable-capacity turbocharger is provided with, wherein
- the leading edge shape in the nozzle blade height direction has a curved-line shape that is formed by the distance from the rotation axis of the nozzle blade to the leading edge changing depending on the nozzle blade height position, and
- the trailing edge shape in the nozzle blade height direction has a straight-line shape that is formed by the distance from the rotation axis of the nozzle blade to the trailing edge being constant irrespective of the nozzle blade height position.
