Abstract
A turbocharger housing comprises a central housing portion having means for rotatably supporting the turbocharger shaft and a pair of end housing portions adapted to be bolted to the central housing portion at mating annular surfaces of each housing portion. In one advantageous form of the present invention, the end housing portions include a recessed wall for defining a flow passageway adjacent a radially expanded wall portion of the central housing, and a plurality of vanes are integrally formed on the end housing portion to extend outwardly from the recessed wall toward a mating annular surface on the central housing portion. One or more sets of radially spaced mating annular surfaces provides a secure engagement between the end housing portions and the central housing portion. Moreover, the end plates are removably secured to the central housing portion so that the turbocharger mechanism can be removed as a unit with the central housing portion.
