Abstract

A valve for diverting the flow of fluid has a housing with an inlet and a plurality of outlets arranged in spaced relation around the housing. A body is positioned within the housing. The body is rotatable relatively to the housing and has an intake port and an exhaust port joined by a void space. The intake port is aligned with the housing inlet and both the intake port and the housing inlet are coaxially aligned with the axis of rotation of the body. The exhaust port is positioned eccentric to the axis and may be aligned with any one of the plurality of housing outlet ports upon rotation of the body relatively to the housing. A seal is positioned between the body and the housing. The seal surrounds the outlets and the exhaust port to prevent leakage when the exhaust port is aligned with an outlet.

First claim

What is claimed is:

1. A valve, comprising:
a housing comprising a sidewall and first and second oppositely disposed end caps attached thereto, said sidewall and said end caps defining a chamber;
an inlet positioned in said first end cap providing fluid communication to said chamber;
a plurality of outlets positioned in said sidewall and providing fluid communication to said chamber;
a substantially solid body positioned within said chamber, said body being rotatable relatively to said housing about an axis coaxially aligned with said inlet;
a void space positioned wholly within said body, said void space having an intake port coaxially aligned with said inlet and an exhaust port alignable with any one of said plurality of outlets positioned in said sidewall upon rotation of said body.

2. The valve according to claim 1 , further comprising:
an opening in said second end cap;
a shaft attached to said body and extending through said opening, said shaft for effecting rotation of said body relatively to said housing.

3. The valve according to claim 1 , wherein said void space has a diameter and defines a curved path between said intake port and said exhaust port, said curved path having a radius of curvature no less than three times said diameter of said void space.

4. The valve according to claim 1 , wherein said void space has a constant diameter between said intake port and said exhaust port.

5. The valve according to claim 1 , further comprising a plurality of tubes attached to said sidewall, each one of said tubes being in fluid communication with one of said outlets in said sidewall.

6. The valve according to claim 1 , wherein said chamber has a conical shape and said body has a conical shape.

7. The valve according to claim 1 , further comprising a seal positioned within said chamber between said body and said sidewall.

8. The valve according to claim 7 , wherein said seal comprises a substrate.

9. The valve according to claim 8 , wherein said substrate is attached to said sidewall, said substrate having a plurality of apertures, each said aperture being aligned with one of said outlets.

10. The valve according to claim 8 , wherein said substrate is attached to said body, said substrate having an aperture aligned with said exhaust port.

11. The valve according to claim 1 , wherein said first end cap is removably mounted on said housing.

12. The valve according to claim 11 , further comprising a coupling having a plurality of segments joined end to end, said segments surrounding said housing and said first end cap and retaining said first end cap to said housing.
