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： A latching solenoid gate valve comprising is disclosed, and includes a housing defining a conduit having a flow path therethrough and a cavity separating the conduit into a first section and a second section. The latching solenoid assembly also includes a gate assembly enclosed within the cavity of the housing and a first solenoid assembly and a second solenoid assembly seated within the cavity with the gate assembly linearly translatable therebetween. The gate assembly includes a first gate member comprising magnetizable material and defining an opening therethrough. The first gate member is linearly movable within the cavity between an open position with the opening aligned with the conduit and a closed position with the opening out of alignment with the conduit. The first gate member is moved linearly from either the open position or the closed position.

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： Restrictors are disclosed that include a body defining a Venturi tube having a throat defining a junction of a converging inlet cone to a diverging outlet cone along a longitudinal axis thereof, and with the converging inlet cone and the diverging outlet cone each defining an inner passageway that transitions as a hyperbolic or parabolic function toward the throat.

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.
