摘要： Aspirators are disclosed herein that include a body defining a Venturi gap between an outlet end of a converging motive section and an inlet end of a diverging discharge section and have a suction port in fluid communication with the Venturi gap. The converging motive section defines a circular-shaped motive inlet and defines an elliptical- or polygonal-shaped motive outlet, and the diverging discharge section defines an elliptical- or polygonal-shaped discharge inlet. In one embodiment, the converging motive section defines an inner passageway that transitions as a hyperbolic function from the circular-shaped motive inlet to the elliptical- or polygonal-shaped motive outlet and the elliptical- or polygonal-shaped motive outlet has an area that is less than the area of the circular-shaped motive inlet.

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： 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.
