Definitions

  • the invention has for its object to remedy or reduce at least one of the drawbacks of the prior art or at least provide a useful alternative to the prior art.
  • a drain loop like the one described above could be a very useful tool for stopping the operation of the motor in a quick and efficient way.
  • the high-pressure path must be drained of working fluid when the operation is to be stopped, and this requires in many cases that the evaporation of the fluid must be continued, while at the same time the working-fluid pump is stopped, in order then to evacuate the working fluid through the expander, possibly through a bypass, but wherein the working fluid will still be in the evaporated state as it is flowing out of the high-pressure path.
  • Such a "normally open” fluid valve contributes to increased safety in that, in the event of a signal drop-out, it will drain the high-pressure path so that the expander stops.
  • the mechanical energy is in turn converted into electric energy by means of the generator 48.
  • the electric energy from the generator 48 is transferred as electric power P EL from the generator 48 via the power/electricity interface 10 to the electric-power converter 12.
