Abstract
The present invention relates to a downhole flow device for controlling a flow of fluid between an annulus and an inner bore of a well tubular metal structure arranged in a borehole. The downhole flow device comprises a tubular part comprising a first opening and an axial extension, and a sliding sleeve configured to slide within the tubular part between a first position covering the opening and a second position fully uncovering the opening, the tubular part comprising a first groove and a second groove, the first groove being arranged at a first distance from the second groove along the axial extension, and the sliding sleeve comprising a projecting part configured to engage the first groove in the first position and the second groove in the second position, wherein the tubular part comprises a third groove configured to be engaged by the projecting part and having a second distance to the second groove which is smaller than the first distance. The present invention furthermore relates to a downhole system for controlling a flow of fluid in a well downhole and to a downhole manipulation method for shifting a position of the downhole flow device of a downhole system.
