摘要： Engine systems have an air induction system, a turbocharger in fluid communication with an intake manifold, an evacuator defining a Venturi gap with a suction port in fluid communication therewith, a relief valve enclosing a piston and defining an inlet and an outlet in selective fluid communication with one another, and a storage tank of high pressure air in fluid communication with the evacuator. The relief valve has a valve element connected to the piston, and the piston divides the housing into a pressurized chamber in fluid communication with the suction port of the evacuator and a bypass portion in fluid communication with the inlet, which is in fluid communication with the compressed air from the turbocharger, and the outlet, which is in fluid communication with the air induction system or atmosphere. A discharge cone of the evacuator is in fluid communication with atmosphere or the air induction system.

摘要： Venturi devices are disclosed herein that include a body defining a Venturi gap between an outlet end of a converging motive section and an inlet end of a diverging discharge section, having a suction port in fluid communication with the Venturi gap, a gate valve linearly translatable to open and close the Venturi gap, and an actuator connected to the gate valve to operatively move the gate valve between an open position and a closed position. The gate valve, in a longitudinal cross-section, is generally U-shaped, thereby having continuous, opposing sides that one each close the motive outlet and the discharge inlet and defining a void between the opposing sides that is in fluid communication with the suction port. The converging motive section defines a circular-shaped motive inlet and defines an elliptical- or polygonal-shaped motive outlet, and the diverging discharge section defines an elliptical- or polygonal-shaped discharge inlet.

摘要： Venturi devices are disclosed that have a housing defining a conduit having a Venturi gap. Downstream of and bypassing the Venturi gap is a bypass check valve that defines an internal cavity having a first seat, a second seat, an inlet port, at least two outlet ports, and a seal member seated therein that is translatable between a closed position against the first seat and an open position against the second seat. The two outlet ports of the bypass check valve enter the conduit at opposing positions disposed a distance from a top of the conduit, which is located at a midsagittal plane of the housing. Further, a transition from a tapering section downstream of the Venturi gap and upstream of each of the two outlet ports to a discharge section downstream of the two outlet ports forms a gradually, continuously tapering interior surface of the conduit.

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： Venturi devices and systems incorporating the Venturi devices are disclosed. The Venturi devices have a body defining a passageway that has a motive section and a discharge section spaced a distance apart from one another to define a Venturi gap. Both the motive section and the discharge section converge toward the Venturi gap. Also, the body defines a first suction port and a second suction port generally opposite one another that are each in fluid communication with the Venturi gap. The Venturi gap is generally wider proximate both the first suction port and the second suction port than at a generally central point therebetween. In a system, the Venturi device has its motive section fluidly connected to a source of motive pressure and one or both of the first and second suction ports in fluid communication with a device requiring vacuum.

摘要： Devices for producing vacuum using the Venturi effect are disclosed that have a motive passageway converging toward a suction chamber, a discharge passageway diverging away from the suction chamber, and a suction passageway, all of which are in fluid communication with the suction chamber. The motive passageway has a single entrance, and subdivides downstream thereof into a plurality of subpassageways, one each leading to one of the plurality of motive exits, which are spaced apart from a discharge entrance of the discharge passageway to define a Venturi gap. The fletch having a plurality of ribs extending between an exterior surface of the generally conically-shaped main body thereof and an interior surface of the motive passageway is disposed in the motive passageway. The ribs divide the motive passageway into the plurality of sub-passageways, each converging fluid flow over the exterior surface thereof toward one of the plurality of motive exits.

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.
