ABSTRACT:
A sliding sleeve valve for downhole use. A tubular main body has a radial flow port there-through and a primary annular seal carried adjacent its inner diameter and spaced longitudinally from the flow port in a first direction. A sleeve is carried co-axially within the main body for selective relative longitudinal movement. The sleeve has a seal section with an outer diameter sized to slidably sealingly engage the primary seal. The sleeve also has a radial aperture through the seal section and a recess in the outer surface of the seal section, surrounding and longer than the radially outer end of the aperture. The sleeve has a closed position, wherein the aperture and recess are longitudinally spaced from the primary seal in the first direction, and an open position, wherein the aperture is longitudinally spaced from the primary seal in a second direction opposite the first. The recess is sized and configured to permit the aperture to pass the primary seal while moving from closed to open position, under given temperature and pressure conditions, without substantial damage to the primary seal.
