CLASS 24: Combustion systems.

The draft regulator according to the present invention can by steam, electricity, water or Are driven by air pressure and should one be put into the state with his help, to keep the steam pressure in the steam boiler as even as possible and to burn the coal, to generate strong drafts by wide opening of the smoke slide, on the other hand the same as possible to limit when the coal is well burned.

By means of the adjusting screws g ' and g ² , the mercury contacts j and j' can be brought closer to or from the armature h. removed and thereby the operation of the device can be regulated.

The respective vapor pressure is passed through the pipe to the manometer e, which is provided with an electrical contact closure. When the vapor pressure rises or falls, the pressure gauge pointer becomes f in. With a rotating movement, it hits the isolated driving pin of the lever g, moves the latter and, as a result, also the armature h. As a result of this alternating movement, the ends of the anchor h dip alternately into the vessels j and j ', and since there is mercury in these, an electrical connection is established.

In the position shown in FIG. 1, the electric current runs from the galvanic battery k through the wire line h ' into the armature h and, since this is connected to the contact fluid in j , through the wire line j ³ into the changeover switch u and its Contact pin u '. From here the current goes through the lever w ¹ · ¹ to the contact pin u ² and then through the lead wire w ^ö to the magnet coils /, in order to be closed in the galvanic battery k after passing through the wire line k '.

As a result, the soft iron η ^{2 of} the magnet coils / are magnetized and attract the connecting plate m with which the valve rod η of the valve ρ is connected. This opens the valve and the pressurized water runs through pipe r with a pressure of about 1.5 atm. under the piston b 'of the cylinder A sealed with a leather sleeve. This takes the smoke slide y with it when it rises, so that the smoke flue is opened.

When the piston b ' rises, the switch u is moved by its lever w ¹ ' ¹ and the switch pins v ' from the contact pins u' and M ² to the contact pins ³ and w ⁴ . The aim of this switching is to let the electric current only act as long as the apparatus is in motion. When the vapor pressure rises, the armature h is switched off from the contact housing j and switched on into the contact ^{housing j 1} by turning the pressure gauge pointer f . This creates an electrical connection in the opposite direction, and the current then runs through the wire j ² to ^{the contact pin w 4} and, since the lever w ¹ * ^{1 is} on the contact pin when the smoke slide is open

Claims (1)

pins u ³ and w ⁴ is located, through this after the contact pin w ³ , from here through the wire line u ⁵ , the solenoids / 'and the wire line A ² to the galvanic battery k, whereby it is closed. As soon as the current runs through the coils / ', their soft irons η ^{3 become} magnetic, as a result of which they attract the connecting plate m' and the valve rod n ' attached to it; the valve p ' is thereby opened and the water flows off through pipe r and the lower part of pipe s . As a result, and by its own weight, the slide will bezw to sink. forced to close the flue. As the slide ^ sinks, the switch u is moved by its lever κ ¹ " ¹ and the driver pins v ' from the contact pins ³ and M ⁴ to the contact pins u' and u ² , ie into its original position. The drain pipe s should also establish a connection between the surface of the piston b ' and the external atmosphere so that no counter pressure or vacuum can arise in the cylinder A. In addition, if the piston leaks, the water should flow out through this pipe. Each time the switch u is switched over , the solenoids / and / ' demagnetized and thereby the valves ρ and p ' closed. The sticking of the anchor is prevented by the paper insulation layer i ² . Furthermore, the lever m ² > ² can be adjusted as required by means of the adjusting screw χ in the elongated hole w in order to thereby adjust the height of the slide and consequently to regulate the cross section of the flue. Patenτ claim: Automatic draft regulator, characterized in that the steam pressure of the boiler or a steam pressure pipe acts with the aid of a manometer (e) on an electrical contact device which, in conjunction with two electromagnets (I and V) and two regulating levers (u ¹ ' ¹ and u ² > ² ) the opening resp. Closing the valves (p and p ') has the effect of influencing the movement of the piston (b ¹ ), which is rigidly connected to the smoke valve (y ), by regulating the inflow and outflow of the propellant and an exact setting of the Smoke slide (y) .
