Abstract
A regulated two-stage turbocharger system is described. The turbocharger system includes high-pressure and low-pressure turbocharger units in communication with one another. The turbocharger system includes a valve system having valve members that are independently controllable so as to selectively control the gas flow into the turbine portions of the high-pressure turbocharger and the low-pressure turbocharger units. The valve members are asymmetric, e.g., they possess differing areas (e.g., perimeters, diameters and/or the like) with respect to one another.
Claims20
A turbocharger system, comprising:
- a high-pressure turbocharger unit;
- a low-pressure turbocharger unit operably associated with the high-pressure turbocharger unit;
- and
- a valve system operably associated with either of the high-pressure and low-pressure turbocharger units;
- wherein the valve system includes at least two valve members operable to selectively meter a gas flow to either of the high-pressure or low-pressure turbocharger units.
A turbocharger system, comprising:
- a high-pressure turbocharger unit having a turbine portion;
- a low-pressure turbocharger unit having a turbine portion, wherein the low-pressure turbocharger unit is operably associated with the high-pressure turbocharger unit;
- and
- a valve system operably associated with either of the turbine portions of the high-pressure and low-pressure turbocharger units;
- wherein the valve system includes at least two valve members operable to selectively meter a gas flow to either of the turbine portions of the high-pressure or low-pressure turbocharger units.
A turbocharger system, comprising:
- a high-pressure turbocharger unit having a turbine portion;
- a low-pressure turbocharger unit having a turbine portion, wherein the low-pressure turbocharger unit is operably associated with the high-pressure turbocharger unit;
- and
- a valve system operably associated with either of the turbine portions of the high-pressure and low-pressure turbocharger units;
- wherein the valve system includes at least two valve members operable to selectively meter a gas flow to either of the turbine portions of the high-pressure or low-pressure turbocharger units;
- wherein the valve members are operable to be independently or sequentially actuated by the valve system.
