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： Noise attenuation units are disclosed that are connectable in a system as part of a fluid flow path. Such units include a housing defining an internal cavity and having a first port and a second port each connectable to a fluid flow path and in fluid communication with one another through the internal cavity, and a noise attenuating member seated in the internal cavity of the housing within the flow of the fluid communication between the first port and the second port. The noise attenuating member enables the fluid communication between the first port and the second port to flow through the noise attenuating member.

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： A piston for an internal combustion engine has a body including an upper combustion wall having an upper combustion surface; cylindrical outer wall with a ring belt region adjacent the upper combustion surface, and a closed annular cooling gallery located in radial alignment with the ring belt region. A cooling medium is contained in the cooling gallery. The cooling gallery has an inner surface including a radially outermost portion extending along the ring belt region. The outermost portion converges from the upper combustion wall toward a longitudinal central axis. During reciprocating motion of the piston, the cooling medium flows and remains in contact with the cooling gallery walls, thereby maximizing the capacity for heat to be transferred from the upper combustion wall to the contained cooling medium and from the cooling medium to the piston body, ring belt region and ultimately to the engine cooling system.

摘要： A corona igniter 20 includes an electrode gap 28 between the central electrode 22 and the insulator 32 and a shell gap 30 between the insulator 32 and the shell 36. The gaps 28, 30 are filled with a filler material 40 to prevent corona discharge 24 in the gaps 28, 30 and to concentrate the energy at a firing tip 58 of the central electrode 22. The filler material 40 may be electrically insulating or conductive. The shell gap width ws may be greatest at a shell lower end 92. The shell gap 30 may also be in a turnover region between a shell upper end 44 and the insulator 32, in which case the filler material 40 is injection molded around the turnover region. During operation of the igniter 20, the filler material 40 provides a reduced voltage drop across the gap 28, 30.
