MULTI-PART CONCENTRIC MANIFOLD AND METHOD OF MAKING THE MANIFOLD
A manifold is provided. The manifold includes a first body having an outer curved surface; a second body having an inner curved surface corresponding to the outer curved surface of the first body; and a groove formed in one or both of the outer and inner curved surfaces, wherein the first body is dimensioned to fit within the second body so that the outer curved surface contacts the inner curved surface and the groove forms a fluid passage located in between the first and second bodies, the fluid passage having an inlet and an outlet. A method for assembling a manifold may also be provided.
1 . A manifold comprising:
a first body having an outer surface;
a second body having an inner surface corresponding to the outer surface of the first body; and
a groove formed in one or both of the outer and inner surfaces, wherein the first body is dimensioned to fit within the second body so that the outer surface contacts the inner surface and the groove forms a fluid passage located in between the first and second bodies, the fluid passage having an inlet and an outlet.
2 . The manifold of claim 1 , wherein the outer surface and the inner surfaces are substantially circular.
3 . The manifold of claim 1 , wherein the first body is friction fit within the second body.
4 . The manifold of claim 1 , wherein the first and second bodies are bonded together with a bonding agent.
5 . The manifold of claim 1 , further comprising an additional groove and the additional groove is fluidly isolated from the groove.
6 . The manifold of claim 1 , wherein the groove is located on the outer surface of the first member.
7 . The manifold of claim 1 , wherein an inlet/outlet for the groove is located on the second body.
8 . The manifold of claim 1 , wherein an inlet/outlet for the groove is located in the first body.
9 . The manifold of claim 1 , further comprising:
a third body having an inner surface and the second body has an outer surface corresponding to the inner surface on the second body; and
a second groove formed in one or both of the outer surface of the second body and the inner surface of the third body, wherein the second body is dimensioned to fit within the third body so that the outer surface on the second body contacts the inner surface on the third body and the second groove forms a fluid passage located in between the second and third bodies.
10 . The manifold of claim 9 , wherein the outer surface and the inner surfaces are substantially circular.
11 . The manifold of claim 9 wherein and the second body is friction fit within the third body.
12 . The manifold of claim 9 , wherein the second and third bodies are bonded together with a bonding agent.
13 . The manifold of claim 9 , wherein an inlet/outlet for the groove is located on the third body.
14 . A method of assembling a manifold comprising:
forming a first body having an outer surface;
forming a second body having an inner surface corresponding to the outer surface of the first body; and
forming a groove in one or both of the outer and inner surfaces, wherein the first body is dimensioned to fit within the second body so that the outer curved surface contacts the inner surface and the groove forms a fluid passage located in between the first and second bodies, the fluid passage having an inlet and an outlet.
15 . The method of claim 14 , further comprising heating the second body thereby expanding it and inserting the first body into the second body.
16 . The method of claim 14 , further comprising:
forming a third body having an inner surface and the second body has an outer surface corresponding to the inner surface on the second body; and
forming a second groove formed in one or both of the outer surface of the second body and the inner surface of the third body, wherein the second body is dimensioned to fit within the third body so that the outer surface on the second body contacts the inner surface on the third body and the second groove forms a fluid passage located in between the second and third bodies.
17 . The method of claim 16 , further including heating the third body thereby expanding it and inserting the second body into the third body.
18 . The method of claim 16 , wherein the second groove crosses over the first groove and the first and second groove do not intersect due to the second groove being located radially outward from the first groove.
19 . The method of claim 14 , further including bonding the first body to the second body.
20 . A manifold comprising:
a first body having an outer surface;
a second body having an inner surface corresponding to the outer surface of the first body; and
means for defining a pathway formed in one or both of the outer and inner surfaces, wherein the first body is dimensioned to fit within the second body and the means for forming a pathway is located in between the first and second bodies, the pathway having an inlet and an outlet.
