摘要： Check valves are disclosed, including check valve included in an aspirator, that includes a housing defining an internal cavity having a first port and a second port both in fluid communication therewith, and a sealing member within the cavity. The sealing member is translatable between a closed position against a first seat within the internal cavity of the housing and an open position against a second seat within the internal cavity of the housing. The sealing member has a sealing material positioned for sealing engagement with the first seat when the sealing member is in the closed position and a reinforcing member positioned for engagement with the second seat when the sealing member is in the open position.

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.
