摘要： A radial turbine impeller includes a turbine wheel module including a first surface and a second surface being mutually opposite in the axial direction of the radial turbine impeller. The radial turbine impeller includes blade modules attached to the turbine wheel module. Each blade module is a single piece of material and includes a body portion and blades connected to the body portion and protruding in the axial direction from the body portion. At least the first surface of the turbine wheel module is provided with one or more annular grooves opening in the axial direction and containing the body portions of the blade modules so that, in each of the grooves, the blade modules are successively in the circumferential direction. The radial turbine impeller further includes a securing system for keeping the body portions of the blade modules in the one or more grooves.

摘要： A compressor housing defines an inlet bore having a first inlet collar disposed therein. The inlet collar is connected to the housing with a first plurality of radially extending posts. The first plurality of posts is removed to detach the inlet collar from the housing, and the inlet collar is removed from the housing. The same or another inlet collar is concentrically located within a liner. The liner can be located at a radial distance around at least a portion of the inlet collar. The inlet collar is connected to the liner by radially inserting a second plurality of posts through the liner and into the inlet collar. An assembly of the liner containing the inlet collar is inserted into the inlet bore of the housing such that the inlet collar forms the inducer bore of the compressor housing.

摘要： A radial turbine includes a radial turbine wheel provided with a main pathway in which blade height progressively increases while curving toward an axial direction from a radial direction. A sub-let is formed on a shroud side of the radial turbine wheel at a position separated from the main inlet in the radial direction and the axial direction. Also, a blade shape that forms the sub-inlet is such that, in a plane orthogonal to the axial line of the radial turbine wheel, a center line of the blade is inclined at a predetermined angle toward the rotation direction with respect to the radial direction.
