Abstract: 1,228,537. Raising and discharging liquids. BAKER OIL TOOLS Inc. Aug. 6, 1969 [Sept. 19, 1968], No.39379/69. Heading F1R. Apparatus for controlling fluid level in a tubular string disposed in a well bore comprises a tubular member connectible in the string, having a passage through which fluid can flow into the tubular string from a place of formation of the fluid and which passage is closed and opened by a valve head engaging a valve seat, fluid-pressure actuated means connected to the valve head and supplied by gas pressure to open the valve head and subjected to pressure of liquid in the tubular string to close the valve head and spring means acting to close the valve head. As shown in Fig. 2 the fluid actuated means comprises a piston 22 moving in a cylinder portion 30 of the tubular member 12. The piston 22 encompasses the reduced diameter portion 25 of a rod 20 the lower end of which has a valve head 19 which rests on a valve seat member 14. Gas under pressure in the casing-tubing K flows through one or more side ports 33 to act upon the piston 22 to elevate the piston and the rod 20 thus opening the valve head 19 against the force of the coil spring 42. The liquid in the well can now flow upwardly through the valve unit until the level in the tubing string F reaches a predetermined height and the pressure of liquid acting downwardly on the piston 22 plus the force of the spring 42 overcomes the upward force of the lifting gas on the piston 22, the valve then shifts to a closed position. When this occurs a gas-lift valve (10) Fig. 1 (not shown) immediately above opens to allow the gas pressure to enter the string and lift the column of liquid. In another embodiment Figs.4a,4b the fluid actuated means comprises a piston 80 fixed to a housing 52 on which moves a cylinder 78 into which is threaded the lower end of a valve rod 76. A valve head 75 is mounted on the valve rod end fits within a valve seat 68 in engagement with its seal 73. Gas under pressure enters into the cylinder space 85 tending to shift the valve rod 76 and valve head 75 out of engagement with the seat 68 against the force of a spring 86. Liquid from the well can then flow via passages 88 through the valve seat 68 and into the tubing string until the pressure in the tubing string acting on the valve head 75 is sufficiently great to close it. The lower end of the rod 76 is formed as a collet having spring like arms 93 enabling the valve to snap into the open and closed position. Lock dogs 56 may be retracted by a retrieving tool (not shown) which becomes coupled to the mandril 55 so that the valve housing 52 may be removed from the tubular member 50. In the form of invention disclosed in Fig. 8 (not shown) the gas flows through a central passage 100 past a check valve 101 and the gas is throttled by a restriction 102 in the passage 100 so that continuous flow of liquid takes place.
