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.

摘要翻译： 公开了一种用于向增压发动机空气系统中的装置提供真空的抽空器。 抽风器限定了一个主体，其包括会聚动力部分，发散排放部分，至少一个吸入口和位于会聚动力部分的出口端与发散排放部分的入口端之间的文丘里间隙。 在出口端和入口端之间测量直线距离。 如果需要在特定的一组操作条件下的更高的抽吸真空度并且如果需要在特定的操作条件下较高的抽吸流量，则需要在长度上增加直线距离，则线距离减小。

摘要： Ejector assemblies and engine systems have 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.
