Patent number: 9803447Abstract: 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.Type: GrantFiled: June 27, 2015Date of Patent: October 31, 2017Assignee: Cameron International CorporationInventors: Johnny E. Jurena, David J. McWhorter, Charles E. Gibbs, Steven F. Shimonek

Publication number: 20150144814Abstract: A ram-type blowout preventer including an operating piston assembly isolated from wellbore pressure effects is provided. In one embodiment, a blowout preventer includes piston coupled to a ram by a connecting rod, and the connecting rod is inserted into a recess in the ram. A pressure-isolating seal may be provided in the recess between the connecting rod and the ram to isolate the end of the connecting rod within the recess from wellbore pressure in the blowout preventer. Additional systems, devices, and methods are also disclosed.Type: ApplicationFiled: February 2, 2015Publication date: May 28, 2015Applicant: CAMERON INTERNATIONAL CORPORATIONInventors: Johnny E.

Patent number: 8857784Abstract: Linear clutches for reducing axial loads in a system are provided. In one embodiment, a system includes a blowout preventer having a ram coupled to an actuation assembly. A locking assembly is positioned within the system to enable an end of the locking sleeve to engage the actuation assembly and to lock the actuation assembly and the ram into place. In this embodiment, the locking sleeve is segmented and includes at least one groove to engage a complementary surface of the actuation assembly. Additional systems, devices, and methods are also disclosed.Type: GrantFiled: September 27, 2012Date of Patent: October 14, 2014Assignee: Cameron International CorporationInventors: Steven F.
