摘要： A Venturi device for producing vacuum from fluids in an engine system has a body defining a Venturi gap separating apart an outlet end of a converging motive section and an inlet end of a diverging discharge section by a lineal distance, and a suction port in fluid communication with the Venturi gap. The converging motive section and the diverging discharge section both gradually, continuously taper toward the Venturi gap, the converging motive section defines a circular-shaped motive inlet and an elliptical- or polygonal-shaped motive outlet, the diverging discharge section defines an elliptical- or polygonal-shaped discharge inlet, and an inner passageway of the converging motive section transitions as a hyperbolic function from the motive inlet to the elliptical- or polygonal-shaped motive outlet.

摘要： Bypass check valves, suitable for bypassing a Venturi gap, are disclosed and include a housing defining an internal cavity having a first seat and a second seat, and a seal member within the internal cavity translatable between a closed position against the first seat and an open position against the second seat. The second seat defines a support structure having a middle region of a predetermine height and a downstream side having a height that is shorter than the predetermined height of the middle region. The seal member is seatable against the second seat with a downstream portion thereof a further distance from the first seat than an upstream portion thereof.

摘要： Ejector assemblies and engine systems including the same are disclosed herein. The ejector assemblies include a pressure regulator in fluid communication with an ejector. The pressure regulator receives boost pressure and selectively allows the boost pressure to pass through a valve opening therein under selected engine conditions and into the ejector as regulated boost pressure. Both the pressure regulator and the ejector each have a conduit defining a passageway that includes a Venturi gap separating the passageway into a converging section and a first diverging section that both narrow toward the Venturi gap. The pressure regulator has a piston operatively connected to a valve mechanism positioned for movement therewith to control the passage of the boost pressure through the valve opening, and the valve mechanism defines a passage therethrough that includes a gradually narrowing portion that is narrower than the valve opening.

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： 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.
