Abstract

An asymmetrical ram button is provided. In one embodiment, a system includes a blowout preventer including such a button. Particularly, the blowout preventer may include an actuation assembly having the asymmetric ram button attached to a connecting rod coupled to a piston. The asymmetric body of the button can engage an internal shoulder of the ram such that a retraction force on the actuation assembly causes the asymmetrical ram button to load against the internal shoulder. Additional systems, devices, and methods are also disclosed.
