Abstract:
A turbine housing of a turbocharge can include a surface that defines a portion of a volute, an annular surface that extends radially inwardly to define a portion of a pressure chamber that is in fluid communication with the volute, a substantially annular plate that defines a portion of the pressure chamber, an annular component, at least one spacer that defines a minimum axial distance between the substantially annular plate and the annular component to define a nozzle that is in fluid communication with the volute and in fluid communication with a turbine wheel space where, responsive to fluid flow in the volute and through the nozzle to the turbine wheel space, the pressure chamber has a fluid pressure that exceeds a fluid pressure of the nozzle to apply a biasing force to the substantially annular plate in an axial direction toward a center housing.

Claim (Index 1):
A turbocharger comprising:\n a center housing; a bearing disposed in a through bore of the center housing wherein the through bore of the center housing defines a longitudinal axis; a shaft rotatably supported by the bearing; a compressor wheel operatively coupled to the shaft; a turbine wheel operatively coupled to the shaft; and a turbine housing assembly operatively coupled to the center housing wherein the turbine housing assembly comprises:\n a turbine housing that comprises a concave surface that defines a portion of a volute wherein the concave surface extends to a substantially annular surface of the turbine housing that extends radially inwardly in a direction toward the longitudinal axis to define a portion of a pressure chamber that is in fluid communication with the volute, \n a substantially annular plate that defines a portion of the pressure chamber, \n an annular component, and \n at least one spacer wherein the at least one spacer defines a minimum axial distance between the substantially annular plate and the annular component to define a nozzle that is in fluid communication with the volute and in fluid communication with a turbine wheel space defined at least in part by the turbine housing, \n wherein, responsive to fluid flow in the volute and through the nozzle to the turbine wheel space, the pressure chamber comprises a fluid pressure that exceeds a fluid pressure of the nozzle to apply a biasing force to the substantially annular plate in an axial direction toward the center housing to maintain the minimum axial distance between the substantially annular plate and the annular component as defined by the at least one spacer.
