  • Wellbore control device
    Patent number: 7779918
    Abstract: A wellbore control device (10) for sealing a wellbore is described. The device has, in a preferred arrangement, two opposed cutting rams (16, 18) which are coupled to respective linkage mechanisms (26, 28). The linkage mechanisms translate axial movement of a piston into radial movement to move the rams towards each other in the device throughbore. This results in an effective wellbore control device having a compact size and shape which can be encompassed within a wellbore.
