Patent number: 11156054Abstract: A packer actuation system for a blowout preventer includes a packer arrangement with an axial passage therethrough, an actuation system which is releasably mechanically connected to the packer arrangement, a contractor arrangement, and a retractor arrangement. The actuation system moves the packer arrangement from an expanded position to a contracted position so as to decrease a dimension of the axial passage, and to move the packer arrangement from the contracted position to the expanded position so as to increase the dimension of the axial passage. The contractor arrangement moves the packer arrangement from the expanded position to the contracted position. The retractor arrangement moves the packer arrangement from the contracted position to the expanded position.Type: GrantFiled: March 28, 2017Date of Patent: October 26, 2021Assignee: ELECTRICAL SUBSEA & DRILLING ASInventors: John L.

Patent number: 4969390Abstract: A new and improved ram locking apparatus for blowout preventer rams which allows the rams to be locked in the closed position and compensates for wear on the sealing elements of the rams. The device consists of a tubular cross containing a rod extension with a tapered end attached to the ram, a hydraulically reciprocal piston with a wedging surface to coact with the tapered end of the rod extensions and hydraulic fluid ports. The tapered end of the rod and the wedge surface of the piston have serrated surfaces to increase friction between the wedging surfaces and provide a self-locking engagement and thereby provide a small compact apparatus.Type: GrantFiled: May 30, 1989Date of Patent: November 13, 1990Assignee: Cooper Industries, Inc.Inventor: Bolie C.
