    A working cylinder is provided, comprising at least one disc-like displacer (120) rotatably supported in a cylindrical block (114), which displacer (120) is arranged between two annular flanges (110) extending radially inwards from said block (114) on each sides of said displacer (120) such that said displacer (120) will be arranged in parallel with said flanges (110) upon rotation, wherein at least one of said flanges (110) comprises a plurality of sections including a first section (112a) having a first temperature, a second section (112b) having a second temperature being lower than said first temperature, and two insulating sections (112c, 112d) completely preventing contact between said first section (112a) and said second section (112b), and wherein said displacer (120) comprises a cutout (122) for rotating a volume of working fluid across the sections (112), which cutout is dimensioned such that for every rotational position it does not overlap the first section (112a) and the second section (112b) at the same time.

    ENERGY CONVERTER OPERATION HEATING AND COOLING IN A CLOSED SYSTEM Based on PV=nrT we use the expansion/retraction of a medium (air, gas, vapor...) ina closed system to get work done. When we heat up the medium we let the pressureoperate on a connected device (for example push a membrane or a piston), andwhen the medium shrinks or retracts, it pulls the pressure operated device.
    (The same principle as in the Stirling Engine). Fig. 1a and 1b shows a segment medium chamber connected to a pressure meter in place of a membrane or cylinder.
    DIFFERENT SETS OF FLANGES EXPOSED TO DIFFERENT TEMPERATURESCONTROLLED SWIRL WITH LARGE AREA HEAT EXCHANGE - ln the segment medium chamber, the medium (air, gas, vapor...) is exposed to hotand cold surfaces in a controlled cycle in a swirl with forced convection. Fig. 2a basicembodyment with hot (red), cold (blue) and neutral (vanilla) surfaces. Fig. 2brotating shaft with quarter segment chamber (cut out slice in a disc) Fig. 2cquarter segment chamber with medium in a swirl PLURALITY OF DISCS RADIALLY EXTENDING FROM SHAFT, EACH DISCHAVING A CUT OUT SECTION (Segment medium chamber) The energy converter keeps the ratio between the surface for exchange and the volume of the medium at a desired level during scaling.
    DISCS EXTENDING BETWEEN FLANGES EXTENDING INTO CYLINDER A large surface is needed to transfer heat into and out of the working medium. lf itwasn't for the segmented design, the volume of the medium would grow with thecube and the surface would only grow with the square. Fig. 3 shows a cross section of the energy converter.
    FOUR SECTORS - TWO CYCLESPRESSURE OF MEDIUM IN CYLINDER INCREASED AT ONE SET OF FLANGESAND DECREASED AT OTHER SET OF FLANGES - During the cycle the medium will pass four totally separated sectors: Neutral(maintaining the swirl) - Hot (energy transfer to the medium) - Neutral (maintainingthe swirl) - Cold (energy transfer from the medium). The medium will never be inmore than two of those sectors at the same time. As the medium passes through thesectors We define the full cycle in two parts: 1) "Warming cycle" and 2) "Coolingcycle" "Warming cycle": a) Neutral-Warm, b) Warm, c) Warm-Neutral makes almost half aturn. The medium in the quarter segment chambers gets warm and the pressure in the whole segmented cylinder goes up.
    "Cooling cycle": Neutral-Cold, Cold, Cold-Neutral makes the otherhalf turn. The medium cools down and the pressure falls in the segmented cylinder. ln between the Warming cycle and the Cooling cycle, as in between the cooling cycleand the Warming cycle, there are very short moments being 100% Neutral, about twodegrees of a 360 circle each.
    The pressure variation can be taken from anywhere in the cylinder, to be used by, forexample, a piston, a membrane, a pressure meter, a pieso elemt or whatever that works with pressure.
    MOVING THE MEDIUM IS CONTROLLING THE CYCLES We move the medium between the hot and cold surfaces with the segmented rotating"pack-man" shaft operated by a motor (that consumes energy). By controling theshaft motor we are able to control how long time the medium is exposed to thewarming and the cooling cycle. We are able to totally control the rpm and the poweroutput within the full span from zero rpm up to a limit beyond the maximumperformance rpm. The maximum performance rpm is where you get the most revolutions still maintaining an effective heat exchange. lnstalling the shaft motor inside de shaft, or outside the segmented cylinder (withmagnetic transmission) the cylinder gets totally sealed. Minimizing the risk for leaks stealing power.
    USING DIFFERENT VAPORS AS A MEDIUM Depending on application, one may use a saturated vapor that has a phase shiftwithin the temperature difference used to run the converter. This gives betterperformance than, say, air. As an example one may use acetic acid ethyl ester in"green" low temperature difference applications.
    CONNECTING MULTIPLE CYLINDERS Connecting two cylinders with 180 degree angle between the segment mediumchambers is favourable for the use of double-acting pistons. Connecting threecylinders with 120 degree angle between the segment medium chambers gives smooth operation using pistons powering a shaft.
    No matter what configuration you choose, the important feature is that you maychange and sync your chamber angels "on the fly" since every cylinder has its ownmotor to control the movements of the pack-man shaft. Fig 4 shows a cross section of the energy converter with three cylinders.
