Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A variable geometry turbine comprising: a fluid space that is formed in a donut shape by a pair of ring-like opposing surfaces arranged to face each other with a certain distance therebetween and that allows fluid flowing from an outer circumferential side to be discharged toward an inner circumferential side; and a plurality of nozzle vanes arranged in the fluid space at certain intervals in a circumferential direction so as to partition the fluid s…
