An embodiment providing a seal assembly for turbomachinery for controlling flow of a fluid medium in a fluid path comprises a casing having an internal pressure load path and a seal carrier chamber. A movable seal carrier is disposed within the seal carrier chamber and interposed between the pressure load path and an external flow path. In addition, a pressure selecting apparatus is coupled to the pressure load path to control flow therethrough. Moreover, the position of the movable seal carrier moves in response to a pressure differential determined by the pressure selecting apparatus between the pressure load path and the external flow path.

The apparatus of claim 1 further comprising a lid section removably disposed on said side walls wherein said lid spans said two side walls, and said first and second end walls. 3. The apparatus of claim 1 wherein said second side wall is longer than said first side wall. 4. The apparatus claim 1 wherein said one or more grooves of each of said sidewalls are aligned with the approximate midpoint of said corresponding surface portion of said other sidewall. 5. The apparatus of claim 1 further comprising at least one handle affixed to at least one or more of said side walls, said first end wall, said second end wall, said bottom plate, and said at least one partition. 6. The apparatus of claim 1 wherein said side walls further comprising an upper side wall portion and lower side wall portion wherein said lower side wall portion includes an array of spaced recesses positioned on top of said lower side wall portion, and said upper side wall portion which extends at least the length of said inside surface of said side wall and includes an array of spaced protrusions that fits into said array of spaced recesses, wherein said recesses and said protrusions form said at least one aperture in said side walls. 7. The apparatus of claim 1 wherein said side walls further comprising a top side plate and lower side wall portion wherein said lower side wall portion includes an array of spaced recesses positioned on top of said lower side wall portion, and said top side plate which extends at least the length of said inside surface of said side wall and includes an array of spaced protrusions that fits into said array of spaced recesses, wherein said recesses and said protrusions form said at least one aperture in said side walls. 8. The apparatus of claim 1 wherein said inside surface has one or more shaping contours spaced adjacent to said one or more grooves. 9. The apparatus of claim 8 wherein said one or more shaping contours has an arch or other decorative shape. 10. The apparatus of claim 9 wherein said arch shape has a radius that is substantially equal to said at least one partition. 11. The apparatus of claim 1 wherein said first end wall is pivotally attached to one end of said sidewalls. 12. The apparatus of claim 1 wherein said second end wall is pivotally attached to a second end of said sidewalls. 13. The apparatus of claim 1 wherein said bottom plate comprising a first section that conforms to said inside surface of said side walls and a second section that is substantially the same thickness as said bottom ledge of said side walls wherein the bottom surface of said bottom plate is in substantial alignment with the outside bottom surface of said bottom ledge of said side walls. 14. The apparatus of claim 13 wherein said first section and said second section are removably attached to each other, are integral pieces fixed to each other, or are a unitary, one-piece component. 15. The apparatus of claim 1 wherein said bottom plate comprising a first section that conforms to said inside surface of said side walls and a second section that is greater than the thickness of said bottom ledge of said side walls, wherein said second section extends under said side walls and a third s
