  • Patent number: 8857313
    Abstract: An actuation system (200) is provided. The actuation system (200) includes a fluid operated actuator (211) and a control valve (230). The control valve (230) is movable between a first position and a second position and is adapted to open a fluid flow path from a pressurized fluid supply (240) to the actuator (211) when the control valve (230) is in the first position. A diverting fluid conduit (246) is provided that is adapted to divert a portion of the pressurized fluid supplied to the actuator (211) when the control valve (230) is in the first position. The pressurized fluid diverted through fluid conduit (246) biases the control valve (230) towards a second position.

  • Patent number: 8261655
    Abstract: A locking piston assembly (100) is provided according to the invention. The locking piston assembly (100) includes a piston chamber (107), a piston rod (106) configured to be substantially extended from and substantially retracted into the piston chamber (107), and a piston head (108) coupled to the piston rod (106) and configured to move reciprocally in the piston chamber (107). The locking piston assembly (100) further includes at least one lock (120) configured to mechanically lock the piston head (108) and the piston rod (106) in at least a substantially fully extended position. The lock (120) is configured to unlock the piston head (108) and the piston rod (106) in a presence of a pressurized fluid provided to retract the piston rod ( 106). The pressurized fluid is introduced into the piston chamber (107) and the piston rod (106) is retracted only after the lock (120) is unlocked.
