Abstract: A pneumatically actuated vacuum pump is disclosed, and includes a body defining a converging motive section, a diverging discharge section, at least one suction port, and a Venturi gap. The Venturi gap is located between an outlet end of the converging motive section and an inlet end of the diverging discharge section. The pneumatically actuated vacuum pump also includes a first check valve fluidly connected to the Venturi gap and the suction port. The pneumatically actuated vacuum pump further includes at least one second gap located in the diverging discharge section of the body downstream of the Venturi gap. A second check valve is fluidly connected to the second gap.

Abstract: Venturi devices and systems incorporating the same are disclosed. The Venturi devices include a lower body defining a passageway having a motive section and a discharge section spaced a distance apart from one another to define a first Venturi gap and a second Venturi gap downstream of the first Venturi gap at a position that divides the discharge section into a first portion between the first and second Venturi gaps and a second portion leading away from the second Venturi gap, and include an upper body defining a suction passageway in fluid communication with both the first and second Venturi gaps. The motive section and the discharge section converge toward the first Venturi gap.

Abstract: A variable flow valve assembly is disclosed, and includes a main body and a piston. The main body defines a chamber, an inlet port, an outlet port, and a wall located between the inlet port and the outlet port. The wall defines a metering orifice for selectively allowing a medium to flow from the inlet port to the outlet port. The piston is moveable within the chamber of the main body in a plurality of partially open positions to vary the amount of medium flowing through the modulation orifice.

Abstract: Ejector assemblies and engine systems including the same are disclosed herein. The ejector assemblies include 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.

Abstract: A sprung gate for a valve having an endless elastic band sandwiched between first and second gate members that each define an opening therethrough in an open position portion thereof, which collectively form a passage through the sprung gate. The first gate member includes a fastener connected to a fastener receiving member of the second gate member thereby securing the first and second gate members together as a unit. This sprung gate unit is operatively connected to an actuator for linear translation within a pocket of a conduit to control fluid flow through the conduit. This assembled device may be manufactured using spin welding to sealingly mate the conduit to a housing enclosing the actuator.

Abstract: 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.

Abstract: 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.

Abstract: A valve assembly is disclosed, and includes an evacuator and a relief valve. The evacuator includes a suction port that selectively applies a vacuum. The relief valve has an open position and a closed position, and includes an inlet, an outlet, a piston that translates within a chamber, and a pressurized chamber. The piston includes a first end and a second end. The pressurized chamber is fluidly connected to the suction port of the evacuator, and is defined in part by the first end of the piston. The piston translates within the pressurized chamber towards the open position if vacuum is applied to the pressurized chamber.
