Abstract
A side-opening sleeve valve having an inner cylindrical barrel with a shaped opening through the wall, an outer cylindrical barrel having shaped opening through the wall, where the barrels are co-annular and rotatable, and a means for rotating the inner barrel relative to the outer barrel between a first open position where the shaped openings overlap to form a side opening into the sleeve valve, and a second closed position where the shaped openings do not overlap. A side-opening valve is used in pigging fluid flush system for a water-less toilet, where a toilet bowl empties into the side opening of the side-opening valve when opened. When the side-opening valve is closed, a pig cleaning system pushes the waste in the side-opening valve to a sewage system.
Claims15
A side opening sleeve valve, including:
- a) an inner cylindrical barrel having a cylindrical wall and a single shaped opening through the wall,
- b) an outer cylindrical barrel having a cylindrical wall and a single shaped opening through the wall, where the inner barrel is disposed co-annularly and rotatably within the outer barrel, and
- c) a means for rotating the inner barrel relative, to the outer barrel between a first open position where the single shaped opening in the inner barrel overlaps with the single shaped opening in the outer barrel to form a side opening into the side-opening sleeve valve, and a second closed position where the single shaped opening of the inner barrel and the single shaped opening of the outer barrel do not overlap.

A side-opening sleeve valve, including:
- a) an inner cylindrical barrel having a cylindrical wall and a single shaped opening through the wall,
- b) an outer cylindrical barrel having a cylindrical wall and a single shaped opening through the wall, where the inner barrel is disposed co-annularly and rotatably within the outer barrel,
- c) a means for rotating the inner barrel relative to the outer barrel between a first open position where the single shaped opening in the inner barrel overlaps with the single shaped opening in the outer barrel to form a side opening into the side-opening sleeve valve, and a second closed position where the single shaped opening of the inner barrel and the single shaped opening of the outer barrel do not overlap, and
- d) a sleeve seal layer disposed between the wall of the inner barrel and the wall of the outer barrel, the sleeve seal layer comprising a cylindrical sheet having an opening that registers with at least one of the opening of the inner barrel and the opening of the outer barrel, to seal between the inner and outer barrels at the periphery of the shaped opening in the outer barrel,
- wherein the outer barrel has a groove formed into the inside surface, and the sleeve seal layer is disposed within said groove.
