VALVE REGULATION FOR TURBOCHARGER

摘要

The present invention provides a two-stage turbocharger unit (10) having a valve assembly (34) that will help to create a smooth transition of exhaust gas energy from the high-pressure (HP) turbine (16) to the low-pressure (LP) turbine (22) . The LP and HP turbines (22, 16) are positioned such that a valve (36) can be in one position to force all of the exhaust gas to flow through the HP turbine (16) and when in another position to force all of the exhaust gas through the LP turbine (22) . When the valve (36) is placed in an intermediary position, the exhaust gas can be variably directed to flow through both turbines (16, 22) , with the percentage of exhaust gas flowing through each turbine (16, 22) being dependent on the position of the valve (36) .
