Abstract
A valve (10) may be used with an internal combustion engine exhaust breathing system (12) and may include a body (60), a partition (62), and a plate (66). The body (60) may define a first port (70) that has a first interior surface (76), and may also define a second port (82) that has a second interior surface (84). The partition (62) may be located within the body (60), may at least partially separate the first port (70) and the second port (82) from each other, and may define an opening (104). The plate (66) may be dimensioned to seat and seal against the opening (104) and against the first and second interior surfaces (76, 84). The plate (66) may rotate, depending on predetermined factors, between a first position and a second position.
Claims21
A product comprising:
- a valve (10) for use with an internal combustion engine exhaust breathing system (12), the valve (10) comprising:
- a body (60) defining a first port (70) having a first interior surface (76), and defining a second port (82) having a second interior surface (84);
- a partition (62) located within the body (60) and at least partially separating the first port (70) and the second port (82), the partition (62) defining an opening (104);
- and
- a plate (66) being dimensioned to seat within the opening (104) and to seat against the first and second interior surfaces (76, 84), the plate (66) selectively rotating between a first position where fluid flows to an exhaust gas recirculation (EGR) cooler (34, 46) and where fluid flows from the EGR cooler (34, 46) and to an exhaust breathing system component, and a second position where fluid flows to the exhaust breathing system component wherein the plate rotates approximately 45 degrees or less.

A product comprising:
- a valve (10) comprising:
- a body (60) defining a first port (70) having a first interior surface (76) and extending from a first inlet (78) and to a first outlet (80), the body (60) defining a second port (82) having a second interior surface (84) and extending from a second inlet (86) and to a second outlet (88),
- a partition (62) located between the first port (70) and the second port (82) in order to separate the first port (70) and the second port (82), the partition (62) defining an opening (104);
- and
- a plate (66) being dimensioned to seat within the opening (104), and being dimensioned to seat against the first and second interior surfaces (76, 84), the plate (66) selectively rotating between a first position where fluid flows from the first inlet (78), through the first port (70), and out the first outlet (80), and where fluid flows from the second inlet (86), through the second port (82), and out the second outlet (88), and a second position where fluid flows from the first inlet (78), through a portion of the first port (70), through a portion of the opening (104), through a portion of the second port (82), and out the second outlet (88) wherein the plate rotates less than 45 degrees.

A product comprising:
- an internal combustion engine exhaust breathing system (12) comprising an exhaust passage (26), a valve (10) located downstream the exhaust passage (26), and an exhaust gas recirculation (EGR) assembly (28, 32) including an EGR cooler (34, 46), the valve (10) comprising:
- a body (60) defining a first port (70) having a first interior surface (76), and defining a second port (82) having a second interior surface (84);

- and a plate (66) being dimensioned to seal the opening (104) and to seat against the first and second interior surfaces (76, 84), the plate (66) electively rotating between a first position where fluid flows between the exhaust passage (26) and the EGR cooler (34, 46) and where fluid flows between the EGR cooler (34, 46) and other components of the EGR assembly (28, 32), and a second position where fluid flows between the exhaust passage (26) and components of the EGR assembly (28, 32) wherein the plate revolves for a total angle of rotation from the first position to the second position of less than 45 degrees.
1 more element
A process comprising:
- providing an internal combustion engine exhaust breathing system (12) comprising an exhaust passage (26), a valve (10) located downstream the exhaust passage (26), and an exhaust gas recirculation (EGR) assembly (28, 32) including an EGR cooler (34, 46);
- providing the valve (10) comprising :
- a body (60) defining a first port (70) and a second port (82);
- a partition (62) separating the first port (70) and the second port (82), the partition (62) defining an opening (104);
- a rod (64) being rotatably carried by the body (60), by the partition (62), or by both;
- and
- a plate (66) rotatable with the rod (64) and being dimensioned to seal the opening (104) and to seal the first port (70) and the second port (82);
- rotating the plate (66) to a first position where fluid flows from the exhaust passage (26) and to the EGR cooler (34, 46), and where fluid flows from the EGR cooler (34, 46) and to other components of the EGR assembly (28, 32);
- and
- rotating the plate (66) to a second position where fluid flows from the exhaust passage (26) and to components of the EGR assembly (28, 32) wherein the plate rotates approximately 45 degrees or less.
