摘要： A device for producing vacuum using the Venturi effect, systems utilizing the device, and methods of making the device are disclosed. The device has a housing defining a Venturi gap, a motive passageway converging toward the Venturi gap and in fluid communication therewith, a discharge passageway diverging away from the Venturi gap and in fluid communication therewith, and a suction passageway in fluid communication with the Venturi gap. The suction passageway has an interior surface with a surface topography that renders the interior surface hydrophobic and has an oleophobic coating applied to the interior surface while maintaining the surface topography.

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.
摘要翻译：公开了用于产生真空的文丘里装置的模具后处理方法，其改善了其排空时间。所述方法包括提供一种模制的文丘里装置，其具有在会聚动力通道的出口端和发散的排放通道的入口端之间限定文丘里间隙的主体，其中出口端限定具有径向向内延伸的闪电的动力出口，端部限定具有径向向内延伸的闪电的排出口。然后，该方法包括将模制的文丘里装置定位成具有朝向喷射喷嘴的会聚动力通道的入口端，或者与朝向喷射喷嘴的发散排放通道的出口端对准，并将喷射介质推进到动力入口或排出口的文丘里装置去除动力出口和排放口中的闪光，反之亦然。

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.
