Abstract

A rotary valve system includes a first body having a first plurality of fluid channels. The first fluid channels have a common first inlet to receive a fluid and a first outlet. The system includes a second body coupled to the first body. The second body has a second plurality of fluid channels. The second fluid channels have a second inlet and a second outlet. The system includes a plate assembly having a plate coupled between the first body and the second body. The plate is movable between at least a first, open position in which the first outlet of at least one of the first fluid channels is in fluid communication with the second inlet of at least one of the second fluid channels and a second, closed position in which the second inlet of each of the second fluid channels is substantially completely obstructed by the plate.

First claim

What is claimed is:

1. A rotary valve system, comprising:
a first valve body having a first plurality of fluid channels, each one of the first plurality of fluid channels having a common first inlet to receive a fluid and a first outlet;
a second valve body coupled to the first valve body, the second valve body having a second plurality of fluid channels, each one of the second plurality of fluid channels having a second inlet and a second outlet, and the second valve body includes a shaft defined internally within the second valve body; and
a plate assembly including a plate coupled between the first valve body and the second valve body and coupled to the shaft for movement relative to the second valve body and the first valve body, the plate defining a plurality of openings, the plate movable between at least a first, open position in which the first outlet of at least one of the first plurality of fluid channels is in fluid communication with the second inlet of at least one of the second plurality of fluid channels and a second, closed position in which the second inlet of each of the second plurality of fluid channels is completely obstructed by the plate, with a first sub-plurality of the second plurality of fluid channels in fluid communication with a plurality of surge ducts and a second sub-plurality of the second plurality of fluid channels in fluid communication with a plurality of load ducts, a first sub-plurality of the first plurality of fluid channels are in selective fluid communication with the first sub-plurality of the second plurality of fluid channels and a second sub-plurality of the first plurality of fluid channels are in selective fluid communication with the second sub-plurality of the second plurality of fluid channels.

2. The rotary valve system of claim 1 , wherein the first plurality of fluid channels diverge within the first valve body to define a first cavity within the first valve body, the first cavity surrounded by the first plurality of fluid channels and the first cavity extends along a longitudinal axis of the rotary valve system.

3. The rotary valve system of claim 1 , wherein the second plurality of fluid channels converge within the second valve body to define a second cavity within the second valve body, the second cavity surrounded by the second plurality of fluid channels.

4. The rotary valve system of claim 1 , further comprising an actuator coupled to the plate assembly that is responsive to one or more control signals to move the plate between the first, closed position, the second, open position and positions in-between the first, closed position and the second, open position.

5. The rotary plate valve system of claim 4 , wherein the plate assembly further comprises a gear having a plurality of gear teeth coupled to the actuator and rotatable by the actuator, and the plate includes a plurality of plate gear teeth that meshingly engage with the plurality of gear teeth such that the rotation of the gear moves the plate between at least the first, open position and the second, closed position.

6. The rotary plate valve system of claim 1 , wherein the first plurality of fluid channels comprise four first fluid channels defined within the first valve body that are spaced apart about a perimeter of the first valve body and the second plurality of fluid channels comprise four second fluid channels defined within the second valve body that are spaced apart about a perimeter of the second valve body, with each one of the first fluid channels in selective fluid communication with a respective one of the second fluid channels.

7. The rotary plate valve system of claim 6 , wherein each one of the four first fluid channels extends from the common first inlet along a common wall and diverges downstream from the common first inlet to define a first cavity, with a portion of the plate assembly received within the first cavity.

8. A rotary valve system, comprising:
a first valve body having a first plurality of fluid channels, each one of the first plurality of fluid channels having a common first inlet to receive a fluid and a first outlet, the first plurality of fluid channels diverging downstream of the common first inlet to define a first cavity within the first valve body, the first cavity surrounded by the first plurality of fluid channels, the first plurality of fluid channels comprise four first fluid channels defined within the first valve body that are spaced apart about a perimeter of the first valve body, each one of the four first fluid channels extends from the common first inlet along a common wall and diverges downstream from the common first inlet to define the first cavity;
a second valve body coupled to the first valve body, the second valve body having a second plurality of fluid channels, each one of the second plurality of fluid channels having a second inlet and a common second outlet, and the second plurality of fluid channels comprise four second fluid channels defined within the second valve body that are spaced apart about a perimeter of the second valve body, with each one of the first fluid channels in selective fluid communication with a respective one of the second fluid channels; and
a plate assembly having a plate coupled between the first valve body and the second valve body, the plate defining a plurality of openings, the plate movable between at least a first, open position in which each first outlet of the first plurality of fluid channels is in fluid communication with a respective second inlet of the second plurality of fluid channels and a second, closed position in which the second inlet of each of the second plurality of fluid channels is completely obstructed by the plate, and a portion of the plate assembly is received within the first cavity.

9. The rotary valve system of claim 8 , further comprising an actuator coupled to the plate assembly that is responsive to one or more control signals to move the plate between the first, closed position, the second, open position and positions in-between the first, closed position and the second, open position.

10. The rotary plate valve system of claim 9 , wherein the plate assembly further comprises a gear having a plurality of gear teeth coupled to the actuator and rotatable by the actuator, and the plate includes a plurality of plate gear teeth that meshingly engage with the plurality of gear teeth such that the rotation of the gear moves the plate between at least the first, open position and the second, closed position.

11. The rotary plate valve system of claim 8 , wherein the second valve body includes a shaft defined internally within the second valve body and the plate is coupled to the shaft for movement relative to the second valve body and the first valve body.

12. The rotary plate valve system of claim 8 , wherein each one of the four second fluid channels extends from the second inlet and converges downstream from the second inlet along a second common wall upstream from the second outlet to define a second cavity within the second valve body, the second cavity surrounded by the second plurality of fluid channels and cooperates with the first cavity to receive the portion of the plate assembly.

13. A rotary valve system, comprising:
a first valve body having a first plurality of fluid channels, each one of the first plurality of fluid channels having a common first inlet to receive a fluid and a first outlet;
a second valve body coupled to the first valve body, the second valve body having a second plurality of fluid channels, each one of the second plurality of fluid channels having a second inlet and a second outlet, the second plurality of f
