摘要：A method for reversible temperature sensitive control of the flow of fluid in oiland/or gas production, involves a control device or an autonomous valve operating bythe Bernoulli principle and includes a moveable disk or body provided within a housing

for opening and closing said valve, involving use of the Curie-effect in order to positionsaid body in a preferred position within said housing at a temperature below a certain,preferred transition or Curie temperature. An apparatus for reversible temperaturesensitive control of the flow of fluid in oil and/or gas production including a controldevice or an autonomous valve operating by the Bernoulli principle and including amoveable disk or body provided within a housing for opening and closing said valve, thebody and housing including a ferromagnetic material having a certain, preferred Curietemperature, the temperature being selected in order to position the body in apreferred position in the housing during installation or operation.
