Abstract
A valve assembly for use in an air management assembly having an engine, an exhaust side, and an intake side, where the valve assembly provides a housing, a plurality of openings in the housing, a valve in the housing, and an actuator operably connected to the valve. The housing is in fluid communication with the exhaust side and the intake side. The plurality of openings in the housing form at least one inlet and at least one outlet in the housing. The valve moves with respect to the plurality of openings.
Claims74
A method comprising:
- providing a system comprising a valve assembly for use with an assembly for a combustion engine, said valve assembly comprising a housing, said housing having a plurality openings for the controlled flow of gas therethrough, a valve in said housing;
- and
- an actuator operably connected to said valve and constructed and arranged to move said valve with respect to said openings to control the flow of gas therethrough, the gas comprising combustion engine exhaust, and wherein said openings comprising a first opening comprising a first inlet or a first outlet, a second opening comprising a second inlet or a second outlet, and a third opening comprising a first outlet or a first inlet;
- causing said actuator to move said valve to a first position wherein said second opening is fully open and said first opening is partially closed, to a second position wherein both said first opening and said second opening are fully open, and to a third position wherein said first opening is fully open and said second opening is at least partially closed, and to a fourth position wherein both said first opening and said second opening are each at least partially closed.
