PARTIALLY DIVIDED TURBINE HOUSING FOR TURBOCHARGERS AND THE LIKE Abstract of the Disclosure: A 360° volute, radial inflow turbine housing has the housing chamber inlet and housing chamber with a radial divider extending circumferentially of the housing chamber for between approximately 180° and 300° dividing the housing chamber into axially adjacent parts for the extent of the divider which ultimately opens circumferentially into a common chamber part extending circumferentially the remainder of the housing chamber. All of the housing chamber divided and common parts communicate generally radially inwardly to a generally central turbine wheel location. At the transition between the housing chamber divided parts into the common part and for the remainder of the chamber, it is preferred for optimum results to maintain the chamber radial cross section in its normal circum- ferential volute reduction sufficiently large such that the chamber will not restrict the progressively diminishing gas flow beyond that which would normally take place under the normal volute reduction as if the chamber divided parts had continued throughout the chamber common part. Additionally, it is preferred that the circumferential termination of the housing chamber divider be generally angled from direct radial initially at the minimum radius and progressively circumferentially to the maximum radius with the greatest circumferential extension of such divider being in the order of between approximately 180° and 300°. -1-
