摘要： Check valves are disclosed that have a housing defining an internal cavity having a first port and a second port both in fluid communication therewith, and having a first seat defined by a first elastomeric V-ring seal and a second seat. and a check valve plate within the internal cavity that is translatable, in response to pressure differentials, between a closed position against the first seat and an open position against the second seat within the internal cavity of the housing. The first elastomeric V-ring seal includes a body having an interference fit to an annular channel defined by the housing and a lip extending from the body in a direction that defines a generally V-shaped void, viewed in cross-section, opening in a direction away from and generally perpendicular to the flow through the elastomeric V-ring seal into the internal cavity.

摘要： Fluidic diodes are disclosed that have a housing defining an inlet and an outlet and a divided fluid passageway therebetween defined by mirror image partitions generally tear-drop shaped spaced apart a first distance from one another by a constant width primary fluid pathway with the tip thereof pointed generally toward the outlet and spaced apart a second distance from an interior wall of the housing to define a constant width secondary fluid pathway. Fluid flow from the inlet to the outlet is through the primary fluid pathway with some additional flow through the secondary fluid pathways joining the primary fluid pathway proximate the outlet for flow together in the same direction, and fluid flow from the outlet to the inlet through the secondary fluid pathways exits the secondary fluid pathways into the primary fluid pathway, proximate the inlet, in a direction substantially opposite the flow in the primary fluid pathway.

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： 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： 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.
