at this point the ball 43 will rotate within the socket 44 and thereby close and prevent the upward flow 46 of well hydrocarbons the ratcheting of the ball valve 42 is in a fashion known in the art in some embodiments when hydrostatic pressure at or above the sea floor or in some embodiments surface of a ground well 48 is lessened or removed as and when the tubular pneumatic fluid line tubular 32 is repaired or replaced then the ball 43 can rotate to open and restore the upward hydrocarbon flow 46 and hydrocarbon flow can resume it is envisioned that in various permutations of the present inventive device the piston w pawl 36 and ball valve 42 can be of varying geometrical and solid shapes as would be known in the art to form a sealing mechanism in one embodiment of the present invention it is envisioned that a hydrostatic or pneumatic fluid line 54 could be attached to the control valve mechanism 30 by which fluid could be pumped into the pressure chamber 52 in such situations pressure in the pressure chamber 52 can be controlled by an external user causing the piston 36 to be actuated by which the ratcheted teeth 40 could be raised or lowered causing the ball valve 42 to engage or disengage the socket 44 the raising or lowering of the ball valve 42 would be actuated by decreases or increases in fluid pressure in the pressure chamber 52 hence increasing pressure could cause the increased fluid to push up or lower the piston 36 in several embodiments.
