摘要： Check valve units having one or more sound attenuating members are disclosed. A check valve unit includes a housing defining an inlet port, an outlet port, and a chamber in fluid communication therewith thereby defining a flow path from the inlet port through the chamber to the outlet port. The chamber includes first and second valve seats and has a sealing member disposed therein that is moveable from a position seated on the first valve seat to a position seated on the second valve seat. A sound attenuating member is disposed in the flow path downstream of the chamber, within the chamber, or both. In another embodiment, the check valve unit includes a Venturi portion in fluid communication with the chamber. The Venturi portion has a fluid junction with the flow path downstream of the chamber or forms the discharge section of the Venturi portion thereby defining the outlet port.

摘要： An aspirator for creating vacuum is disclosed that includes a housing defining a fluid passageway with a first tapering portion and a second tapering portion. Each tapering portion has a larger internal opening and a smaller internal opening, the smaller openings facing one another. The aspirator includes a gate positioned between and in fluid communication with the first and second tapering portions, the gate having a first Venturi tube with a Venturi opening creating vacuum when fluid flows in a direction and a second Venturi tube with a Venturi opening that creates vacuum when fluid flows in the opposite direction. The Venturi openings are in fluid communication with a suction port, and the first and second Venturi tubes may provide different mass flow rates through the aspirator. An engine system having an aspirator with a gate having a first bore and a second bore and an actuator is also disclosed.

摘要： Recirculation systems for engine intake air are disclosed having a turbocharger compressor with an inlet and an outlet, a recirculation pathway connecting fluid flow from the outlet of the turbocharger compressor to fluid flow into the inlet of the turbocharger compressor, and a recirculation valve assembly controlling fluid flow through the recirculation pathway. The recirculation valve assembly includes an actuator operating a valve coupled to an aspirator assembly that produces vacuum when the fluid flows through the recirculation pathway from the inlet to the outlet and when fluid flows through the recirculation pathway from the outlet to the inlet. Fluid flows through the recirculation pathway from the outlet to the inlet when the turbocharger generates boost. The vacuum generated by the aspirator assembly is in fluid communication with the actuator to move the valve between two or more positions.

摘要： An engine system having a flowpath between a junction upstream of a turbocharger and an intake manifold that includes an ejector and an aspirator connected in parallel relative to one another within the flowpath is disclosed. The motive flow through the ejector is in the opposite direction relative to the direction of the motive flow through the aspirator, and both the ejector and the aspirator have a suction port fluidly coupled to a device requiring vacuum. The engine system also includes a first check valve disposed in control of the motive flow through the ejector and a second check valve disposed in control of the motive flow through the aspirator and may also include a control valve in fluid communication within the flowpath upstream or downstream of the ejector and the aspirator that controls the flow into and/or out of both thereof.
