摘要

Apparatus for remotely in a well controlled applications, components for such apparatus, devices for remote indication state for such devices and methods related thereto. An expandable device can comprise a tubular body, a plunger valve and a sleeve to push.The tubular body may include a passage of fluid through the same extension, and the plunger D valve can be prepared in the interior of the tubular body, the piston valve can be prepared in interir of tubular body.The plunger valve configured to move axially within the tubular body responds to a pressure of fluid passing through the perforation of the fluid passage and configured to selectively control the flow of fluid to the inside of an annular chamber.The sleeve of the push can be prepared in the interior of the tubular body and coupled to at least one characteristic expandable, that responds to the flow of fluid into the annular chamber that extends the functionality of at least one expandable. In addition, the expandable apparatus may be configured to generate a signal that indicates the function extension of at least one expandable.
