ABSTRACT:
In order to reduce the overall dimensions of the housing of a turbine which forms a vital part of an exhaust gas powered supercharger (viz., turbocharger), the opening in which a cover member is mounted, is rendered eccentric with respect to the axis of rotation of the turbine impeller in a manner that diameter of the opening can be reduced while still maintaining a surface within the housing which must be precision machined, sufficiently within the shadow of the eccentric opening as to be readily visible and thus permit ready production and assembly of a capacity varying nozzle arrangement which forms a vital part of the device. By reducing the diameter of the opening, the diameter of the cover and the degree to which attachment flanges on the housing and cover extend out from the housing can be notably reduced.
