Abstract
Disclosed are systems and methods for mechanically reclosing a hydraulically actuated sliding side door of a sleeve assembly. One sleeve assembly includes a housing defining one or more flow ports, a sliding sleeve arranged within the housing and movable between a closed position and an open position and back to the closed position, wherein, when in the closed position, the outer sleeve occludes the one or more flow ports, and, when in the open position, the one or more flow ports are exposed. A piston is movably arranged within a piston bore defined in the housing, and a locking mechanism is arranged within the piston bore and configured to engage the piston with the sliding sleeve, thereby allowing the piston to move the sliding sleeve to the open position.
