TURBOMACHINE
First Claim
1. A variable geometry turbine comprising:
- a turbine wheel mounted for rotation about a turbine axis within a housing, the housing defining an annular inlet surrounding the turbine wheel and defined between first and second inlet sidewalls;
a cylindrical sleeve axially movable across the annular inlet to vary the size of a gas flow path through the inlet;
the annular inlet divided into axially adjacent annular portions by at least one annular baffle which is axially spaced from the first and second inlet sidewalls;
inlet formations extending axially across at least two of said annular portions defined by the or each baffle so as to divide said annular inlet into at least two axially offset inlet passages;
the baffle(s) and inlet formations forming part of a nozzle assembly located within said annular inlet;
wherein first and second components of the nozzle assembly define complementary features which co-operate to connect together said first and second components.
