    DETAILED DESCRIPTION
    [0015] According to some embodiments, a generally circular shaped manifold 10 isprovided. The manifold 10 may include an inner body 12. The inner body 12 may have anouter surface 14 of the inner body 12. Optionally, the inner body 12 may have a void or hole16 in its center portion. In other embodiments, the inner body 12 may be solid at the centerportion.
    [0016] Grooves or pathways 18, 20, 22, and 24 may be formed on the outer surface14 of the inner body 12. The grooves 18, 20, 22, and 24 are pathways which allow a fluid toflow within the manifold 10. For example, in some embodiments, various axial pathways 26may be fluidly connected to each other via the grooves or pathways 18, 20, 22, and 24.
    [0017] When the inner body 12 is tightly fit within the outer body 30, as shown inFIG. 2, the grooves or pathways 18, 20, 22, and 24 are fluidly isolated from each other. Thefluid flows through the pathways 18, 20, 22, and 24 to provide fluid communication within themanifold 10 to various axial pathways 26. In some embodiments, the fluid may be hydraulicfluid. The hydraulic fluid may be at relatively high pressure so the fitting of the inner body 12 to the outer body 30 must the tightly fit or sealed to maintain fluid isolation betweenpathways 18, 20, 22 and 24. One of ordinary skill in the art after reviewing this disclosurewill understand that the pressure of any fluids formed through the pathways 18, 20, 22, and24, will need to be at a pressure less than a pressure required to separate the inner body 12from the outer body 30 in order to maintain fluid isolation between the various pathways.
    [0018] In some embodiments, the inner body 12 is press fit within the outer body 30.
    In other words, an initial dimension of the inner surface 32 of the outer body 30 may besmaller than the initial outer surface 14 of the inner body 12. In other embodiments of theinvention, an adhesive may be used to fasten or seal the inner body 12 with in the outerbody 30. In other embodiments, fasteners may be used.
    [0019] In some embodiments, the outer body 30 may be heated so that the innersurface 32 expands. The inner body 12 may be then inserted into the outer body 30. Whenthe outer body 30 cools it shrinks and tightly engages the inner body 14. In otherembodiments, other methods of connecting the inner 14 and outer body 30 may be used.
    [0020] On the outer surface 34 of the outer member 30, hydraulic ports 36 arelocated about various positions. The positions of the hydraulic ports 36 coincide so that theyalign with one of the grooves or pathways 18, 20, 22, and 24 allowing fluid communicationbetween the hydraulic ports 36 and one of the grooves or pathways 18, 20, 22, and 24. Insome embodiments, the hydraulic ports 36 may be located on blocks 38 located on the outersurface 34 of the outer member 30 as illustrated in the FIGs. As configured in the FIGs,hydraulic fluid may flow either in or out of the hydraulic ports 36 through the grooves orpathways 18, 20, 22, and 24 and through the axial pathways 26. In some embodiments ofthe invention, the hydraulic ports 36 may be in fluid communication with one or more of theaxial pathways 26.
    [0021] The grooves 18, 20, 22, and 24 may also have turns 25. The turns 25 providea radial opening to fluidly connect the grooves 18, 20, 22, and 24 to one or more axialpathways 26.
    [0022] A hydraulic port 36 may be part of the specific pathway 27. As a result,hydraulic fluid may flow to or from a hydraulic port 36 to a specific axial pathway 27.
    [0023] The turns 25 may terminate at the groove, 18, 20, 22, and 24 and be athrough hole that fluidly connects the groove 22 to the axial pathways 26. However, theturns 25 are not limited to ends or terminations of the grooves 18, 20, 22 and 24 but mayalso occur at an intermediate point along the fluid pathway as illustrated by referencednumeral 27 in FIG. 1 along the pathway 22. Furthermore, the hydraulic ports 36 may belocated over the turns 25 and the pathways 18, 20, 22, and 24 as illustrated in FIG. 2 or theymay be located at intermediate positions on pathways as illustrated in FIGS. 3 and 4.
    [0024] As an example, a specific hydraulic pathway indicated as referenced innumeral 28 may include specific axial pathway 27 and the groove indicated by referencenumeral 22. The groove 22 is terminated with a turn 25 which provides fluid communicationbetween the groove 22 and the axial pathways 26.
    [0025] FIG. 4 is an exploded view and FIG. 3 is an assembled view of the manifold10. In the embodiments shown in FIGS. 3 and 4, the manifold 10 includes and inner body12 an intermediate body 42 and an outer body 30. The inner body 12 includes axialpathways 26, the axial pathways 26 are in fluid communication with the grooves 48, radialpathways 50 and the hydraulic ports 36.
    [0026] The axial pathways 26 are connected via the radial pathway 50 to the turns25. The turns 25 are fluidly connected to the groove 48 on the intermediate body 42 whichis, in turn, fluidly connected to the hydraulic ports 36 in the blocks 38 on the outer body 30.Alternatively, the axial pathways 26 may be fluidly connected via the radial pathways 50 thegroove 18 on the innerbody 12. The groove 18 on the innerbody 12 may be fluidlyconnected to one of the hydraulic ports 36 on the outerbody, 30 via a second radial pathway56 located on the intermediate body 42.
    [0027] One of ordinary skill in the art after reviewing this disclosure will understandhow to connect or isolate varies axial pathways 26 from various grooves 48, turns 25, aradial pathways 50 and hydraulic ports 36.
    [0028] As a result, anyone of the axial pathways 26 may be connected to one of thehydraulic ports 36 through either a groove 18, 20, 22, or 24 on the innerbody 12 or a groove48 on the intermediate body 42 via the turns 25 or radial pathways 50. Thus, the fluidconnections may be routed along the manifold 10 without being fluidly connected with eachother. As shown in Figs. 3 and 4, the pathways defined by the grooves 18 or 48 may evencross over each other (one pathway being on the inner body 12 and the other on theintermediate body 42) but are not fluidly connected.
    [0029] While only a certain number of axial pathways 26, grooves 18, 20, 22 and 24,turns 25 being, radial pathways 50 and hydraulic ports 36 are shown, one of ordinary skill inthe art will understand that more of fewer may be used to achieve a desired result.
    [0030] Similar to that described above, the innerbody 12 may fit within theintermediate body 42. The intermediate body 42 may fit within the outer body 30. It may bedesirable in some embodiments for the connections 52 between the innerbody 12 and theintermediate body 42 to be fluid tight so that fluid does not leak out from the groove 18 orthe radial pathways 50. This may be accomplished in several ways. For example, theinnerbody 12 may be press fit with the intermediate body 42. In other embodiments, theintermediate body 42 is heated as to expand. Once the intermediate body 42 hasexpanded, the innerbody 12 can be inserted into the intermediate body 42. As theintermediate body 42 cools, it will shrink, thereby tightening and making fluid tight theconnection 52 between the innerbody 12 and the intermediate body 42.
    [0031] Similarly, it may be desirable for the connection between the intermediatebody 42 and the outer body 30 to also be fluid tight. Similar to that described above, theintermediate body 42 may be press fit with the outerbody 30. In some embodiments, theouterbody 30 heated thereby expanding allowing the intermediate body 42 to be insertedinto the outerbody 30. As the outerbody 30 cools, it will shrink and thereby form a fluid tightconnection to the intermediate body 42.
    [0032] In other embodiments the connection 52 between the intermediate body 42and the innerbody 12 and/or the connection 54 between the intermediate body 42 and theouterbody 30 may also be accomplished using adhesives, sealants, and or fasteners inorder to help the connections 52, 54 to be fluid tight. In other emobidments, other ways offastening the bodies 14, 30 and 42 may be used.
    [0033] It is anticipated that some embodiments that the fluid that will be flowingthrough the manifold will be hydraulic fluid under pressure. However, in other embodiments,other fluids may be used. Fluids may be in liquid or gas form. Hydraulic fluid is mentionedhere only as an example and is in no way limiting the invention to hydraulic manifolds.
    [0034] The grooves 18, 20, 22, 24 and 48 are shown and described to be on theouter surfaces 14 and 44 of the inner or intermediate bodies 12 and 42. After reviewing thisdisclosure, one of ordinary skill in the art will appreciate that the grooves 18, 20, 22, 24 and48 could also be located on the inner surfaces 32 and 46 of the intermediate 42 or outer 30bodies or both. The outer surfaces 14 and 42 of the inner and intermediate bodies 12 and24 and the inner surfaces 32 and 46 of the intermediate 42 and outer bodies 30.
    [0035] The many features and advantages of the invention are apparent from the detailedspecification, and thus, it is intended by the appended claims to cover all such features andadvantages of the invention which fall within the true spirit and scope of the invention.Further, since numerous modifications and variations will readily occur to those skilled in theart, it is not desired to limit the invention to the exact construction and operation illustratedand described, and accordingly, all suitable modifications and equivalents may be resortedto, falling within the scope of the invention.
