The installation includes a thermostat T placed in cooling water or under the direct or indirect influence of this water. A thermostat can be a mercury thermometer, a metal thermostat, a bimetallic contact, or a thermoelement. The thermostat is connected through the coil of the relay 1I (Fig.) To the metal mass (housing) I, and through the conductor a to the battery B. The battery is connected via a wire to

ground or mass

for example, with

carriage body (car, plane). To the other pole of the battery S is connected through a fuse the main switch S, which can be bipolar; in the latter case, it also includes a wire about the and d circuit of the incendiary current along with switch S, which serves to turn on the ignition of the internal combustion engine. The conductor is connected to the thermometer's mercury. A wire b, shunt the zsiguate chain rf, is connected to a hollow metal contact e, as well as to the coil of relay III. Contact e is placed at the point that mercury reaches at a temperature of about 35. In addition, contact e is connected via relay contacts / to a contact pin, e, placed at the point that mercury reaches at cooling water temperature 20. Relay III together with thermostat D electrically connected to relay II via contacts / and A, through wires b to i, both relays connected to common ground (ground) E. In addition, relay P and ill are connected by conductors r and o to relay I, to relay contact k, with electromagnetic cleaner R burner nozzles, as well as with heater H, in parallel with which the signal lamp / .. is turned on. Heater H serves to heat the fuel in the burner. Electromagnetic cleaner R and the coil of the relay I are connected via bimetallic contact with the ground (mass) E. Relay contact k is connected to the petrol fuel pump. Figure Z with the penetration device Z, The petrol pump and the ignition device have a well-known device. The second end of the winding of the gasoline pump P is connected to the mass E. The second end of the primary winding of the incendiary device Z is connected to the mass E via a bimetallic contact. The bimetallic contacts of the shooting range can be connected to one common bimetallic contact (see the dotted wire in Fig. 1). The secondary circuit of the incendiary device Z contains on one side a spark gap /

on the other hand directly connected to the mass E.

For heating, there is a burner that consumes light hydrocarbons, such as gasoline, kerosene, etc., which has a well-known device. Fuel, such as gasoline, is supplied by an electric pump P, whose operation is described below. The cleaner / cleans the burner nozzle, from which the fuel enters the burner, which eliminates the extinction of the flame and the interruption of heating in case of contamination of the nozzle.

Cooling water to be heated enters through the nozzle 2 (Fig. 3) into the heat exchanger / and exits through the nozzle 3. In the chamber 4 of the apparatus / burner 5 of a known type is placed. The fuel comes from pump P through pipe 6 to the annular channel 7, where it evaporates, passes through pipes 8, 8 (flash 5) to nozzle 9, and through pipe 10 passes to burner head 77, from where it leaves through openings 75. Here it ignites as described below. The heat generated is evenly distributed by screen 14 and passes upward through pipes 76, and the water surrounding these pipes is heated. Excess heat leaves the heat exchanger through the holes 77. The heat exchanger is fixed; the arat is fixed on the main plate 26 with a nut / 5- The screen J4 is fixed on three pillars 21 screwed to the same plate 20. The pump f can be of any known type. It sucks the fuel from the fuel tank and injects it through the tube 6 into the burner 5. The tube 6 is preferably supplied with a throttle device (not shown in the drawing), for example, several layers of felt and metal filter grids, due to which the fuel acquires a uniform speed, so that the burner is not observed to supply fuel in uneven jolts. In order for the vaporized fuel to for some reason not be able to penetrate back into the pump, the tube 6 is rolled up in the form of several spiral turns 6 (FIG. 9) between the throttle device and the burner.

If fuel vapors fall into these coils, they will condense and become liquid.

A safety net 23 is placed between the nozzle 9 and the pipe 10 so that no contaminants can penetrate the nozzle from the outside. For supplying fresh air to chamber 4 and to burner 5, holes 24 are provided in the casing of the heat exchanger 7, also covered with a double safety net (filter). In front of the openings 17, there is also a dual predrag a grid (filter).

On one of the racks 21 there is a bimetallic contact p (Fig. 3), and between the remaining two racks 2 / there is a bimetallic contact n (Fig. 6), which is very close to heater N. In addition, a bimetallic reinforcement is attached to one of the edges of the screen 14 lane 28, at the free end of which there is a resetting screw, which is located adjacent to the burner head // and sits at the bottom. As soon as the burner is heated up during the start-up of the installation, lane 25 begins to more strongly press the head // to its stand, so that the head does not move, even if the installation is 1, fixed on the car or carriage. The heater H is always adjacent to the annular channel 7 due to screws 30.

A spark gap (FIGS. 6, 7) is formed between the burner head 11 and the grip pin 31 placed in the insulating tube 32 and fastened to the clip 83 located on the plate 20. The plate 20 is screwed to the plate 34 (FIG. 9j, on which pump P is fixed, incendiary device Z and placed in relay box K are relays 1, II, III.There are protective cover over device Z and box K. The tilt-exchanger casing / is provided at the bottom with a circular flange protruding behind the -55 ring that is screwed to the plate} 0. If the screws 56 are unscrewed, the device / can be Redo around its axis, whichever which side thereto suitable, conductive supply tube.

When the device is operating, if tem1; the cooling water circuit is below 20, turning the switch S turns on the thermostat G to the battery B. Simultaneously, the current flows through the relay contact k and the wire /, through the heater // n signal lamp L. There is 1 heating and its evaporation, with lamp L indicating that the heater is working properly. At the same time, the circuit is closed through the nozzle cleaner R. The scraper starts to operate and cleans the nozzle channel from the contaminants present in it. Relay contacts / g relay III are closed by mechanical force. The relay contacts / open when the relay is energized 11, and the contacts / g when the relay I is energized. As soon as the heater H reaches the proper temperature, the bimetallic contact n opens the cleaner circuit R and the relay I, as a result of which the relay contacts k are closed a petrol fuel pump P and an incendiary device Z. The scrubber needle is removed by a spring from the nozzle channel. Gasoline fuel pump P begins to supply gasoline to the heated burner. Due to the ignition of a spark through the gap / ignition of fuel evaporated in the chamber / heater I. The burner takes effect and heats the cooling water, for example, in the coil, in the boiler, etc. Due to the heat from the burner flame, the bimetallic contacts of the tire or the circuit breaks. the interconnection between t and p, the p contacts and interrupt the circuits of the heater H, the signal lamp L and the incendiary devices Z.

As the cooling water temperature increases, mercury reaches g contact gravity g, and no circuit is yet closed. The fuel is heated by the burner itself, as the latter is at that time in operation. When the temperature of the cooling water rises to 35 °, the thermostat's mercury T will come into contact with the contact e. The relay lit is energized, its contacts /; open

the fuel pump P is turned off and the burner flame is extinguished. By expanding the contacts / g, the relay circuit II is interrupted, and the contacts / are closed. The installation ceases to operate until the temperature again drops below 20 °.

The bimetallic contacts m, p and p during their cooling again close their circuits and, thus, the chains of heater H, signal lamp L, relay I, cleaner / and incendiary device Z are prepared for their subsequent operation. If the temperature drops below 20, then, due to the break of the contact of mercury with pin g, and consequently, due to the interruption of the circuit of relay III, the relay contacts / g are closed under the action of a spring, and all the above processes begin to repeat again. With the incendiary value of the internal combustion engine closed, all the instruments can be turned off with the aid of rovoda 1) when relay III is energized, since the cooling water is then heated by the engine. The same function can be performed automatically by a thermostat, namely, when it reaches 35 °, the thermostat initiates a relay W, and the apparatus automatically switches off. You can also combine relay II and 1P into one open, its switching relay I, (Fig. 2).

A bimetallic contact can be included in the main electric circuit of the heat exchanger, which, in case of known overheating, i.e. when water disappears in the engine casing or in the boiler of the apparatus, turns off the electric current. In this case, the boiler is protected from overheating.

It is advisable to insert a safety device in the form of a closed vessel (Fig. 11) into the pipe supplying fuel from the pump P so that if the gasoline tank is empty, the heat exchanger continues to work for several more hours so that under these conditions x protect the engine from freezing. A tube for gasoline supply, Zhodnt 3 is the upper part of the vessel, and

Oensin flows out of the vessel through a tube immersed in it, the opening of which is located at the very bottom of the vessel.

Instead of relay I, a bimetallic switch could be used, and the induction incendiary device could be replaced by a glowing coil. Bimetallic contacts can be conveniently supplied with mechanical spring devices. Instead of the automatic action of the nozzle cleaner, manual operation of the cleaner with a push button can be arranged. In many cases, a device with a catalytic furnace can be used as a heat source.

In the installation described, the model can be successfully applied the nozzle cleaner shown in FIG. Behind.

A cover J03 is screwed onto the body 101 of the burner nozzle 9, in which, between the sealing rings 104 and 705, there is a plate 10 o with a tube guiding the solenoid core W7. Plate 106 is secured in its position with the sleeve over. The body of the nozzle is closed water-insulated from all sides with the exception of the orifice, directed by its1, its needle. The core 107 runs freely in the guide tube of the IOS plate and is provided with a /// bulge at the end that is opposite to the needle 114. The current is supplied from the clamp 113 to which one electrical conductor is connected.

To activate the scrubber, the solenoid is energized, and the thickening /// is drawn into the solenoid. The core 107 and the needle 114 move upward, the needle removing contaminants from the nozzle p. Downwardly collected fuel is collected in space 115.
