Abstract:
A two-stage valve assembly for a turbocharger includes a movable primary valve adapted to open and close a valve seat of the turbocharger. The primary valve has at least one opening extending axially therethrough. The two-stage valve assembly also includes a movable secondary valve coupled to the primary valve to open and close the at least one opening of the primary valve. The two-stage valve assembly further includes a spring disposed between the primary valve and the secondary valve to seat the secondary valve against the primary valve. The secondary valve is adapted to be coupled to a valve arm of the turbocharger such that relative small movement of the valve arm causes the secondary valve to move and open the opening to allow some exhaust gas of the turbocharger to escape through the at least one opening without moving the primary valve relative to the valve seat.

Claim (Index 17):
A turbocharger for receiving exhaust gas from an internal combustion engine, said turbocharger comprising:\n a turbine housing comprising a valve seat and defining a turbine housing interior; a rotatable turbine wheel disposed within said turbine housing interior for receiving the exhaust gas; and a two-stage valve assembly coupled to said valve seat and adapted to divert a portion of the exhaust gas away from said turbine wheel, said two-stage valve assembly comprising a movable primary valve to open and close said valve seat, said primary valve having at least one opening extending axially therethrough, a movable secondary valve coupled to said primary valve to open and close said at least one opening of said primary valve, and a spring disposed between said primary valve and said secondary valve to seat said secondary valve against said primary valve, wherein said secondary valve is coupled to a valve arm of the turbocharger such that relative small movement of the valve arm causes said secondary valve to move and open said at least one opening to allow some of the exhaust gas of the turbocharger to escape through said at least one opening without moving said primary valve relative to the valve seat.
