    摘要： Devices for producing vacuum using the Venturi effect have a housing defining a suction chamber, a motive passageway converging toward the suction chamber, a discharge passageway diverging away from the suction chamber, and a suction passageway in fluid communication with the suction chamber. A solenoid valve is positioned in the suction passageway and has an elongate sealing member received inside a coil, a first seal seat at a first end of the coil, and a second seal seat at the second end of the coil. The elongate sealing member is translatable within the coil between the first seal seat and the second seal seat, which define an open position and a closed position. 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.

    摘要： An evacuator for supplying vacuum to a device in a boosted engine air system is disclosed. The evacuator defines a body comprising a converging motive section, a diverging discharge section, at least one suction port, and a Venturi gap located between an outlet end of the converging motive section and an inlet end of the diverging discharge section. A lineal distance is measured between the outlet end and the inlet end. The lineal distance is decreased in length if higher suction vacuum at a specific set of operating conditions is required and the lineal distances is increased in length if higher suction flow rate at the specific set of operating conditions is required.

    摘要： 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.

    摘要： Methods for post-mold processing a Venturi device for generating vacuum are disclosed that improve the evacuation time thereof. The methods include providing a molded Venturi device having a body defining a Venturi gap between an outlet end of a converging motive passageway and an inlet end of a diverging discharge passageway, where the outlet end defines a motive exit having flash extending radially inward and the inlet end defines a discharge inlet having flash extending radially inward. Then, the method includes positioning the molded Venturi device with an inlet end of the converging motive passageway facing a blasting nozzle or with an outlet end of a diverging discharge passageway facing a blasting nozzle, and propelling blasting media into the motive inlet or the discharge exit of the Venturi device to remove the flash in the motive exit and in the discharge inlet, or vice versa.
