Actuation Bladder Controlled Downhole Devices

摘要

Various implementations described herein refer to a downhole device having a body with a cavity. The downhole device includes a mechanical element disposed within the cavity. The mechanical element has a base with a left-extending member and a right-extending member that holds the mechanical element in position within an interior space of the cavity. The downhole device includes an inflatable bladder disposed within the cavity between an interior sidewall of the cavity and the base of the mechanical element. The inflatable bladder has an opening on one end for receiving hydraulic fluid, and the inflatable bladder is activated and deactivated to selectively displace the mechanical element in and out of the cavity.
