  • the outer body part 62a is provided with a thread connection 64 for screwing the power generator 60 into the housing 6 and with a fluid chamber 66 having a fluid inlet 68 and two fluid outlets 70, 72 extending in diverging directions.
  • a magnetic oscillator 74 is arranged in the fluid chamber 66, the oscillator 74 being provided with two supports 76 of triangular cross-sectional shape, each support having an edge resting in a groove (not shown) provided in the inner body part 62b in a manner allowing angular oscillation of the oscillator 74 relative to said edge.

  • the selection of said different inner diameters is discussed hereinafter in relation to normal operation of the production valve 1.
  • each controllable valve A of a respective production valve 1 is kept in the open mode. In this mode produced gas flows via the inlet openings 18 into the flow passage 10 at maximum flow rate. As the gas flows along the impeller 54 the latter is rotated, resulting in rotation of the shaft 52 and the magnets 58. An electric current is thereby generated in the coil 60, which current flows via the control system to the battery and thereby charges the battery. Since critical flow of the gas does not occur at the location of the closure member 12, but instead in the choke 26, the closure member 12 is not subjected to enhanced erosion as a result of gas flowing at critical flow rate along the closure member.
  • a coded acoustic signal representing an instruction to move the closure member 12 a selected distance into the flow passage 10 is generated in the main casing. This can be done, for example, by inducing a sequence of metallic object impacts on the main casing.
  • the acoustic signal travels via the main casing, the branch casing 2 and the lock mandrel 4 to the acoustic sensor which induces the microprocessor to control the stepper motor 30 so as to rotate the drive shaft 32 a selected number of revolutions commensurate with the required movement of the closure member 12.
  • the second gear-wheel rotates and thereby moves the spindle 38 and the closure member 12 over said selected distance into the flow passage 10.
  • the flow openings 18 are thereby partly covered so that gas can only flow at a reduced flow rate via the inlet openings 18 to the outlet 19.
  • the coded acoustic signal now represents an instruction to move the closure member 12 against the seat surface 16 of the housing 6.
  • the closure member 12 is moved against the seat surface 16 so that the controllable valve A is in the closed mode.
  • the annular shoulder 22 of the tube slotted 20 contacts the stop ring 24, and the tube 20 exerts a tensile force to the closure member 12 biasing the closure member 12 away from the seat surface 16.
  • a coded acoustic signal representing an instruction to move the closure member 12 to the open position thereof is generated in the main casing. Initial movement of the closure member 12 from the closed position to the open position thereof is promoted by the tensile force from the slotted tube 20.
  • Normal operation of the modified version of the embodiment of Fig. 1 is similar to normal operation of the embodiment of Fig. 1, except that electric current is generated by the alternative power generator 60 instead of the power generator C.
  • gas which enters the fluid chamber 66 via fluid inlet 68 flows through the fluid passages 66a, 66b along the oscillator 74 and further through the fluid outlets 70, 72.
  • the feed-back conduit 79 causes a Coanda effect to occur in the fluid passages 66a, 66b causing flow of gas into the outlets 70, 72 in an alternating manner.
  • angular oscillation of the magnetic oscillator 74 occurs around the support edges of the supports 76.
  • An electric current is thereby generated in the coils 80, 82, which current flows via the control system to the battery and thereby charges the battery.
