Turbine flow regulating valve system

摘要

A regulated two-stage turbocharger system (10, 100) is described. The turbocharger system (10, 100) includes high-pressure and low-pressure turbocharger units (102, 104) in communication with one another. The turbocharger system (10, 100) includes a valve system (200) having valve members (28, 30, 202, 204) that are independently controllable so as to selectively control the gas flow into the turbine portions (12, 14) of the high-pressure turbocharger and the low-pressure turbocharger units (102, 104). The valve members (28, 30, 202, 204) are asymmetric, e.g., they possess differing areas (e.g., perimeters, diameters and/or the like) with respect to one another.
