Abstract:
1. A downhole flow control tool, comprising: a housing having a flow passage; an actuator movably disposed in the housing and being actuatatable between first and second conditions; a closure member movably disposed in the flow passage and operated by the actuator, the closure member having a closed condition at least partially restricting fluid flow through the flow passage in response to the actuator having the first condition, the closure member having an opened condition removing the flow restriction in response to the actuator having the second condition; and a restricting member axially fixed in the flow passage, at least a portion of the restricting member being laterally movable in the flow passage and being passively operated by the actuator, the restricting member having a restrictive condition at least partially restricting mechanical passage through the flow passage in response to the actuator having the first condition, the restricting member having an unrestrictive condition removing the mechanical restriction in response to the actuator having the second condition.
