Claim:
An expandable apparatus, comprising: a tubular body comprising a fluid passageway extending through an inner bore; a push sleeve disposed within the inner bore of the tubular body and coupled to one or more expandable features, the push sleeve comprising an upper annular end surface in communication with an upper annular chamber between the push sleeve and the tubular body separate from the fluid passageway and a lower annular end surface in communication with a lower annular chamber between the push sleeve and the tubular body separate from the fluid passageway, wherein the lower annular end surface has a larger surface area than the upper annular end surface, the push sleeve configured to move axially responsive to a flow of drilling fluid through the fluid passageway and into the lower annular chamber to extend the one or more expandable features; and a valve within the tubular body configured to selectively control the flow of drilling fluid from the fluid passageway into the lower annular chamber.
