, a holding frame 20 , a spring 22 , a tube 21 with a print 23 and a plug 24 , a friction wheel 26 with teeth 27 on its end face, supported on a pin 25 in the holding frame 20 , a fourth,
A pawl 28 with teeth 48, shown enlarged in FIG.
9. Rotating ring 31 with return spring 30 and lid 32
Consists of.

The controller R, which is illustrated in detail in FIGS. 7 and 8, comprises a valve member 13 that is slidable longitudinally relative to a valve seat 33, an adjustment lever 16 that is pivotably supported on a pin 34; It consists of an adjusting spring 17, an adjusting rod 15 with an adjusting tube 14 of a balance spring 39, and a valve plate 40 with a fixing bush 41.

The combustion section consists of a burner tube 42, two windings 7, 8 of a spring with a large diameter, a catalyst 43 held between an inner spring 44 and an outer spring 45, and a conically wound spring section 46 of the front flap. .

The base body 47 supports the tube 1 on the one hand and the control mechanism R on the other hand.
Alternatively, it serves to support the hair clip mechanism 10 , 11 , 12 , with the base body 47 itself being fixedly arranged in the fuel tank 2 . The air passage is indicated by L, through which fresh air can flow into the combustion space B. The curling trowel according to the invention operates as follows: when the adjusting member 35 is turned to the 0N position, gas flows from the fuel tank 2 through the valves 13, 33 and the combustion tube 42, and is wound in the conical shape of the spring 44. It flows through the curved part 46 into the space between the ignition part Z and the combustion part.

Only the ring 31 is rotated to ignite the combustion gas.

During rotation, this ring 31 causes the rotary member 18 to rotate with it or to cause this part 18 to undergo a rotational movement. The tappet 29, which rests against the cam surface 19, is moved axially, since one end of the tappet 29 always follows the movement of the cam surface 19 due to the force of the spring 30. The axial movement of the tappet 29 causes the pawl 28, which is in rotatable contact with the pin 25, to be pivoted by the bent end 53 of the tappet 29. At this time, the teeth 48 of the pawl 28 mesh with the teeth on the ratcheted end face of the friction wheel 26, and the teeth 48 of the pawl 28 mesh with the teeth of the ratchet type end face of the friction wheel 26, which engages the teeth 48 of the pawl 28.
Make a slight rotational movement around 5.

Print 23 receiving the elastic force of spring 22 in tube 21
rubs against the rotating friction wheel 26, producing a spark that ignites the gas mixture in the chamber between the ignition section Z and the combustion section. The tappet 29 is held in the area of the friction wheel 26 and is guided by a sheet metal tongue 50, the front end of which projects into an opening in the flange fixed at 49 of the holding frame 20. . A tube 21 containing a print 23 is held by curved tongues 50, 51 of the frame 20 and is supported in a hole in the frame 20 at the front. The return spring 30 is pressed against the disk indicated by 52, and the disk 5
2 itself rests on the end of the tappet 29, which is bent in a U-shape.

After the gas mixture has been ignited in the space between the ignition part Z and the combustion part, catalytic combustion is started, for which the gas is constantly pumped through the valve 13.
, 33 in a controlled manner.

The valve member 13 is moved relative to the valve seat 33 by means of an adjusting lever 16, so that the lever 16 is moved by the pin 34.
It is pivotably supported.

The adjusting lever 16 has the shape shown in FIGS. 10 to 12 and is loaded at its free end by a control damping spring 39, the adjusting spring 17 having its free end is engaged with an adjustment member 35, which member 35 is connected to the base body 4.
7 or is rotatably supported by the fuel tank 2.
When the adjusting member 35 is turned to the 0N position, the adjusting spring 17 pivots to the left in the drawing, since the free end of the adjusting spring 17 rises in this direction and touches the sloping control cam surface 36. This is because they are engaged. As a result, the control damping spring 39, which was initially biased, is unloaded and likewise pushes the end of the adjusting lever 16, which was loaded thereby, to the left. The adjusting lever 16 then lifts the valve 13 from the valve seat 33 and thus opens the valve. The adjusting lever 16 is further acted upon by a temperature control mechanism, which consists of an adjusting tube 14 with an adjusting rod 15 movable therein, the tube 14 and the rod 15 being connected at their front end (combustion (within the area of 1), the end of the tube 14 on the grip side is fixedly arranged on the valve plate 40 via a fastening bushing 41, and the end of the adjustment 15 on the grip side For the adjusting lever 16 shown in FIGS. 10 to 12, the valves 13, 33 are closed when the curling trowel is heated up and are subsequently opened again when it cools down.

The regulating tube 14 reacts positively to the effects of temperature, ie it is stretched to a large extent, while the regulating rod 15 is stretched relatively little. The difference in length between the tube 14 and the rod 15 produces an adjustment stroke or stroke in which one end of the adjustment lever 16 is moved. The gas flow passing through 13, 33 is restricted in the maximum open position by small precision holes in section 33, which allow only relatively small amounts of gas to escape.

When the adjusting member 35 is turned to the 0FF position, the adjusting spring 17 is unloaded and the control damper is closed so that the valves 13, 33 are closed in a gas-tight manner in each case independently of the heating state of the regulating tube 14. 39 are tightened (pressed together). 1st

Battery current flows from battery 57 through compression spring 92, contact pieces 90, 79, 80 and wires 61, 63 to filament 60, then through wire 62 and contact piece 95, and returns to the battery. The filament 60 ignites the fuel/air mixture flowing into the combustion space B'' and the catalytic oxidation process begins in the catalyst 77. The catalyst 77 consists of a platinum-coated quartz wool sock, with This compression-molded quartz wool into a sock-shaped body is closed towards the front, ie towards the ignition mechanism Z'', and has a number of holes 94, 95 for the combustion gas outlet. The thin-walled combustion tube 78 is covered with a thin-walled combustion tube 78.

The fuel tank 54, which is designed as a grip, is closed towards the rear by a tap 96 and is limited from the front by a valve body 97. The valve body 97 has a valve bore 98 in which a spring-loaded valve member 100 is supported slidably in the longitudinal direction. Valve member 100 is sealed against valve bore 98 by annular seal 99 . The rearward end of the valve member 100 has a rubber disk 76 which, in the shown off position, closes the outflow of fuel through the bore 101 and the valve nozzle 101. 75 designates a plug made of sintered metal, in which the fuel vaporizes and thus reaches the valve port 103 from the wick 74.

70, 71, 72 and 73 represent foams which purify the fuel present in the fuel tank 54 and remove the fuel from the wick 7, especially when the fuel tank is only partially filled.

Under the pressure of the loaded spring 104, the valve member 100 now slides to the left into its open position, so that the combustion gases flow through the valve nozzle 102, the mixing tube 111, the combustion tube 78 and the bore 9.
4,95 to the catalyst 77, where it is combusted without sparks. If the temperature in the combustion space B'' rises too much, the regulating tube 120 extends in the longitudinal direction to a greater extent than the regulating rod 119, and the regulating tube and the regulating rod are fixedly connected to each other at the left free end 112. Therefore, as a result of this difference in stretching, the right end of the adjustment rod is moved to the left, and at this time, the adjustment lever 117 is moved clockwise around the support pin 105.
Adjustment lever 117 slides valve member 100 to the right to the closed position. While the valve lever 106 is turned to the left, the control mechanisms 119, 112, 120, 105, 117 can arbitrarily control the outflow of gas from the valve nozzle 102. In the 0FF position of the adjustment member 107 shown in FIG. 13, the adjustment lever 117 is locked in its closed position by the valve lever 106.
