    Abstract: Devices for producing vacuum using the Venturi effect are disclosed that have a housing defining a suction chamber, a motive passageway converging toward the suction chamber and in fluid communication therewith, a discharge passageway diverging away from the suction chamber and in fluid communication therewith, and a suction passageway in fluid communication with the suction chamber. Within the suction chamber, a motive exit of the motive passageway is generally aligned with and spaced apart from a discharge entrance of the discharge passageway to define a Venturi gap, and the suction passageway enters the suction chamber at a position that generates about a 180 degree change in the direction of suction flow from the suction passageway to the discharge passageway. Also or alternately, the motive passageway terminates in a spout protruding into the suction chamber disposed spaced apart from all one or more sidewalls of the suction chamber.

    Abstract: 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.

    Abstract: A magnetic actuator assembly is disclosed, and includes a core, wiring, and a gate assembly. The core is constructed of a magnetic material, and includes a first end and a second end. The wiring is wound around a portion of the core. A predetermined amount of electric current is applied to the wiring to induce a magnetic field within the core. The gate assembly is positioned between the first end and a second end of the core. The gate assembly comprises a first gate member traveling between the first end and a second end of the core based on a threshold force being applied to the gate assembly. The threshold force is created by the magnetic field.
