Abstract

PURPOSE:To keep a constant combustion condition by a method wherein when a shape memory alloy detects an increased temperature of a wick and near the liquid fuel, a volume of exposed wick from the upper opening is displaced by a small amount. CONSTITUTION:The lower end of a coil member 23 composed of a shape memory alloy is engaged and fixed. This coil 23 shows a transformation point of 30 deg.C, for example, and at a temperature below this transformation point it is retracted and if it exceeds the transformation point, the upper portion of the coil 23 is abutted against the stepped part 24 of the outer cylinder 5. A wick holder 10 is descended under a resistance force of the coil 23. The descending volume of the wick is selected such that the upper part of the wick 3 is always kept exposed out of the opening 7 and the flame is not diminished. In this way, the coil 23 is arranged near the wick 3 and the liquid fuel 2, and when the surrounding temperature is increased, the exposed volume of the wick 3 from the opening 7 is kept small and the condition of the combustion is kept constant.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a combustion regulating device for liquid fuel in, for example, a petroleum Vokgur stove.

Background Art In conventional oil portable stoves, the ambient temperature is low at the beginning of combustion, so the combustion state is maintained at the desired temperature. knee t'
However, when the surrounding air rises due to its combustion, the amount of evaporation from the kerosene increases, and the flame spreads, causing the kerosene to extinguish. Therefore, it is necessary to operate to reduce the exposure of the core, which is troublesome ◇ Purpose of the present invention (1) To automatically maintain a constant distance of one step in the distance. ?: Combustion of liquid fuel J, Section 51 is to provide all 1 blue r.

Example, 11 Figure 1, part of the example of Honhi Akira's Kazuya Muri, j, J
It is an r-plane view. Oil portable stove fuel tank l
Kerosene 2, which is lumber and fuel, is stored inside.

This kerosene 2 has a wick 3 made of cylindrical cloth, etc.]':
part is immersed. The capital of this core 3 is the inner cylinder 4 and the outer cylinder f51.
If you go north from the 14-6 iji"+I core that fits in from the 5 and 14"j-, you can sink into this open lower. To the north of the inner cylinder 4, a burner 7 and a burner 7 are disposed to the north of the open lower part, in which the core 8 is hollowed out over the entire circumference in the circumferential direction.

Figure 2 shows llJ connected to core 3! I'J' is a perspective view. A core holder 1o is wound around the middle one return portion of the core 3. On the side wall of the core holder IO, there is a rack 11 extending along the pib line. Rack 1]

Insert the core, the position end j (15) of the vibrator 14 is supported by the oil pan 15, and the core, J
The cap nut 16 screwed into the lower end of the I11 pipe 14 ((11 is supported by the !IJ, di!I shaft 13
A fitting 17 is fixed to the shaft end 3. The chrysanthemum i1'a l8 in the northern part of the tank 1 is airtightly supported via a barragin 20 fixed to the lower end 19 of the outer cylinder 5.

By saying 17elriJ1, the pinion 12 is lowered from the rack, and this VC causes the core holder 1 to be lowered.
0 is 1. It moves up and down at a ratio of 1:1 between the cylinder 3, the inner cylinder 4, and the outer cylinder 5. In this way, core 3 is exposed from the open lower part! Behind the scenes, the exposure meter is strange.
can do.

A Y-shaped outward facing flange 2 is provided on the north part of the core hole 2 and the reader 10.
1 has a pair of locking pieces 22 extending outward as shown in FIG. As shown in FIG. 4, the lower end of the 23rd coil (V section) made of a shape memory alloy is fixed to this stopper piece 22 to keep it constant. These carp 7 and 23 have a temperature of, for example, 30°C at the 1M point. and the northern part of Coil 23,
As shown in Figure 6, the tree hits the general girder 24 of the outer cylinder 5. Due to the drag of this 23, the core boulder 10 is lowered by the lower part. Select a variable height that is exposed when hanging from % key 07 and does not cause the flame to go out.

In this way, the VC coil 23 is provided near the core 3 and the two-strand single-strand f42, and when the temperature around them becomes northern, the amount of exposure of the core 3 from the open lower part is reduced.
The fuel level is kept constant.

In the third gear cusp] 11 5C from Roa; jP may be barked once again so that it is hit.

As described in the book 9d, when the temperature in the vicinity of the wick and liquid fuel rises when the temperature of the 11-year-old memory alloy is increased, the exposure from the opening on the end of the wick - Since the I meter is made to have a small displacement, it becomes possible to maintain the combustion rate constant.
