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.

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： Check valves, Venturi devices and engines that include the check valves are disclosed. The check valves define an internal cavity having a first port and a second port, a first seat and a second seat, and a translatable seal disk. The first seat is proximate the first port and has a first annular seal bead, and a second annular seal bead radially inward from the first annular seal bead. The seal disk has a first sealing portion seatable against the first annular seal bead and a second sealing portion seatable against the second annular seal bead (both of a first thickness), an intermediate portion between the first and second sealing portions of a second thickness, and a lip portion defining the outer periphery of the seal disk of a third thickness. The second thickness is greater than the first thickness, and the third thickness is less than the first thickness.
