According to the listed PSllen takes place the regulation directly or in reverse, d. H. a pressure increase can either be a decrease or an increase of the resistance between the electrodes.

The steam generator can have various embodiments. (It basically contains everything within a closed space a source of heat and Flttssj & lt, being one or the other can be chosen as a standard in the negative direction. In particular, the heat source can be contained in the generator chamber due to the fluid resistance between the two Liquid immersed electrodes or by a solid be formed electrically heat-resistant, which is in contact with the liquid or in a tight container very or is included in the lower threshold. The rule factor is then the flow, which in these liquid or solid Resistors fileAt.

The control factor can, however, also be the temperature of a fluid which flows in a constant amount through a housing arranged in the housing contained in the xu Yerdaapfende FlussIgkelt.

The device shown in FIG. 1 has two plate-shaped electrodes 2 and 3 in a vessel containing a conductive liquid up to the envelope, which are suspended from a flat rod h by rigid conductors 2a and 3a and power supply connections 21 and 3b. The latter rests on a bellows 5, which is fed by a generator 6 attached to the upper part of the vessel 1. In the embodiment shown, the latter has a feed line 6a for a vaporizable liquid (for example distilled mass). This supply is located above a shell 7 “which is constantly heated by a resistor 7a. The control factor consists of strobe pulses which control the electrosis protective device 8. A safety valve 9 prevents excessive increase in the pressure in the generator, while the water condensed into this generator through a capillary tube, for example a dummy wick in a tube is deducted. The condensation of the steam is facilitated by cooling fins 11.

can be moved between electrodes 2 and 3. The kit of the same liquid as the vessel 1 filled Daiapf- cencrator C is supplied either via an immersed resistor or preferably by the current flowing between the two auxiliary electrodes 16 and 17, the via insulated conductors I3 and 19 to the cells carried by the lid .18 * and 19a are connected. Per generator C contains an upper opening 20 and a lower opening 21, each of which is controlled by an ahn which can be operated from the outside by means of handles 22 and 23 which are accessible on the surface of the cover.

When a dip occurs in generator C , lifters 5A and 5E are pressurized and wall 15 is raised, thus exposing a greater area of electrodes 2 and 3 , preventing the resistance of the fluid between these electrodes. If the wall 15 is in its lower position (axiinler ViAerstatid), the value of this resistance is increased by the formation of the electrodes, the saddles 2c and 3 (e carry, which are diagonally opposite and then only by the Wall 15. A corresponding design of the electrodes is thus shown below, after any non-linear Qeset *, changing the fluid resistance as a function of the displacement of the wall 15. The electrodes 16 and 17 can also - as shown - prevent bits and are diagonally opposite inner ones Flscbentellen be designed in such a way that after an intensive steam formation imposing the best position of the wall 15, the situation is stabilized, that is, the tightness of the steam generated by the steam emanating from the upper opening 20 in an oil wall is not affected.

The regulation of the exit cross-sections of the openings 20 and 21 by the taps permits the determination of the tent of pressurization of the generator and the value of the overpressure obtained for a given power converted into the steam generator. The regulation of the cock controlling the opening 21 is permitted thus «on resulting from the return of the liquid resulting transition phenomena (vibrations). In summary, the laws of change can be expected the regulation by the shape of the main and filling electrodes according to the choice of the dimensions of the parts of the device, through the regulation of the current controlled by means of Susserer resistors by the old help of handles 22 and 23 operated taps can be set.

For starting an electric asynchronous motor, for example the electrolytic resistance from the beginning in dea the motor is energized or a branched off part of the current flowing through the motor feeds the steam generator, raised. The steam in the steam generator then rises rapidly and causes the expulsion of liquid from the generator and the vacuum set of the siphon, whatever is connected with the displacement of the wall 15 upwards, the value of the fluid resistance will be soait to sur completion of the start-up process progressively reduced.

If the flow of the electrodes is sufficient, one can leave the fluid resistance in the circuit without causing a voltage drop greater than 1 volt, whereby one the pressure level of the generator on one due to the passage of current Maintains sufficient value · For this particular type of application of starting mines Asynehron motor can dl · Movement of the jack so «ingastivided since» her full stroke just at the end the start-up electrode of the motor is reached and at the end of the stroke
