Filed:

Jun 30, 2000

Appl. No.:

09/608767

Inventors:

John C. Green - Sterling Heights MI
Pete Brykailo - Auburn Hills MI
Richard J. Vaughan - Auburn Hills MI
Daniel P. OBrien - Dixon IL
Thomas A. Horn - Eastpointe MI
Bennett J. Arndt - Canton MI

Assignee:

BorgWarner Inc. - Troy MI

International Classification:

F02M 2507

US Classification:

12356827, 12356829

Abstract:

An exhaust gas recirculation system for an internal combustion engine including a valve body having an exhaust port adapted for fluid communication with a source of exhaust gas, an intake port adapted for fluid communication with the intake manifold of an internal combustion engine, and a valve member movably supported within the body between open and closed positions thereby controlling the flow of exhaust gas from the exhaust port to the intake port. A diaphragm housing is operatively mounted to the valve body and supported thereby. The diaphragm housing defines a vacuum cavity in fluid communication with a source of negative pressure and an atmosphere cavity in fluid communication with a source of second pressure. A diaphragm member is disposed between the vacuum and atmosphere cavities and is operatively connected to the valve member. The diaphragm member is movable in one direction in response to negative pressure induced in the vacuum cavity and in the opposite direction in response to a biasing force to move the valve member between its open and closed position.

Assignee:

Cooper Technology Services, LLC - Findlay OH

International Classification:

F02M 2507

US Classification:

12356812, 12356827

Abstract:

An exhaust gas recirculation (EGR) cooling system includes a valve and a cooler. A motor opens the valve allowing hot fluid exhaust gas to flow into the valve. Cooling fluid continuously flows in and circulated around the valve, reducing the amount of heat transfer from the hot fluid to the valve components. The hot fluid travels through a plurality of tubes in the cooler, continuing to transfer heat to the cooling fluid. As the hot fluid is cooled, the unburned gas in the hot fluid is recycled to be burned by the engine.

Assignee:

Cooper Technology Services, LLC - Findlay OH

International Classification:

F02M 2507

US Classification:

1235682, 12356821, 12356823, 12356818

Abstract:

An EGR valve apparatus regulates the amount of exhaust gas recirculated in an EGR system. The EGR valves are opened or closed by a rotatable shaft which is actuated by a motor. Alternatively, the valves can be balanced on the shaft, the valves moving in opposing direction during rotation. An inline poppet can be employed to overcome pressure in the system prior to movement of the valves. In another alternative embodiment, the motor rotates threaded shaft to move a pintle towards and away from an orifice.

Inventors:

John Townsend - Bloomfield Hills MI, US

Richard Vaughan - Berkley MI, US

International Classification:

B60R022/00

US Classification:

280/801100, 280/806000

Abstract:

A restraint presentation system is disclosed that includes a movable presenting member, such as an armrest or an actuating arm, that moves between a presenting position and a storage position and a restraint belt connected to a tensioning mechanism. The presenting member preferably has a concave shaped portion on a distal end thereof that captures a contact portion of the restraint belt to position the restraint belt in an operational position so as to be accessible to a vehicle occupant. The tensioning mechanism biases the restraint belt into a retracted position when the presenting member is in the storage position such that the contact portion of the restraint belt is in a co-linear relationship with the concave shaped portion of the presenting member.
