As is well known, the electric heating type automatic yoke of a vaporizer is made of bimetal 1' as shown in Fig. 4.
is heated by the heater 2', the bimetal 1' is thermally deformed, and the valve 5' is opened via a link etc., and the heat transfer from the heater 2' to the bimetal 1' is This is accomplished by two methods: conductive heat transfer through the shaft 4' and heat transfer by radiation, in which heat radiated from the heating element 2' is transferred directly to the bimetal 1'.

In this case, regarding heat transfer by radiation, the distance between the side surface of the bimetal 1' and the surface of the heater 2' (indicated by l in FIG. 5) varies due to the dents and bulges on the side surface of the bimetal 1'. This causes variations in the amount of thermal radiation received by the bimetal 1', which causes asymmetry in the thermal deformation of the bimetal 1', which causes variations in the opening speed and opening angle of the autochoke valve 3'. .

Then, the base end of the bimetal 18 is fixed to one end 17 of the small diameter portion 16b of the bimetal shaft 16 that protrudes from the heat insulating plate 15 (located on the left side of the heat insulating plate 15 in the figure), and is connected to the above-mentioned chiyoke valve shaft 5, and is located behind the heat insulating plate 15 (in the figure, the insulating plate 1
A heater 22 is installed at the other end 21 of the large diameter portion 16c of the bimetal shaft 16 (located on the right side of 5). That is, a heat insulating plate 15 for insulating the radiant heat of the heater 22 is interposed in the space between the heat generating surface of the heater 22 and the side surface of the bimetal 18, and the heat of the heater 22 is transmitted to the bimetal 18 via the bimetal shaft 16. This means that only conductive heat is transferred. The heater 22 is embedded in a spiral shape in the surface of a ceramic plate member, for example, and is connected to a power source 24 via an ignition switch 29, and its heating surface is connected to the other end of the bimetal shaft 16. The bimetal shaft 16 is attached to the other end 21 of the bimetal shaft 16 so as to be in contact with the other end 21. However, it may be attached to the inner peripheral surface 26 of the other end 21 as shown in the second figure, or it may be attached to the outer peripheral surface 27 of the other end 21 as shown in the third figure. Furthermore, a cylindrical body 28 surrounding the large diameter portion 16c of the bimetal shaft 16 and the heater 22 is integrally formed on the back surface of the heat insulating plate 15.

When the engine is started, the heater 22 is energized,
The heater 22 generates heat. The heat from the heater 22 is then transmitted to the bimetal shaft 16 and then to the bimetal 18. That is, the heat of the heater 22 is conductively transferred to the bimetal 18. Then, the bimetal 18 is deformed, the spring force of the bimetal gradually weakens, and the valve 6 opens.

Now, in the heat transfer process above, the heater 2
Even if radiant heat is emitted from the heating surface of the heater 22 and the bimetal 18, the heat insulating plate 15 made of synthetic resin is interposed in the space between the heater 22 and the bimetal 18.
It doesn't get through to 8. Therefore, variations in thermal deformation of the bimetal 18 due to heat transfer of radiant heat are prevented, and variations in the opening speed and opening angle of the choke valve 6 are also prevented.

In particular, the bimetal shaft 16 is divided into a small diameter part 16b and a large diameter part 16c by the stepped part 16a, and the small diameter part 16b is passed through the through hole 14 of the heat insulating plate 15.
The stepped portion receiving surface 15a of the heat insulating plate 15 is brought into contact with the stepped portion 16a, and the insulating plate 15 is placed in contact with the inner wall surface 13 of the cover 11.
Since it is supported by the heater 22, the radiant heat from the heater 22 is less likely to be transmitted to the bimetal 18 side, and variations in the opening speed and opening angle of the chiyoke valve 6 caused by the transfer of radiant heat are further prevented.

Moreover, since the heat insulating plate 15 itself constitutes a support body for the bimetal shaft 16, there is no need to separately provide a support body for the bimetal shaft 16, making it easy to assemble these electrothermal automatic yoke mechanisms.

As detailed above, according to the present invention, the electrothermal type has a structure that completely eliminates heat transfer due to radiation from the heater and deforms the bimetal using only conductive heat transferred to the bimetal via the bimetal shaft. It is possible to provide a carburetor with an auto-ch yoke, and therefore it is possible to provide an electrothermal auto-ch yoke-equipped carburetor that is free from variations in the opening speed of the chyo yoke caused by heat transfer by radiation and variations in the opening angle. Therefore, it is possible to provide an electric heating automatic yoke mechanism that is easy to assemble and has a heat insulating plate for insulating radiant heat transfer.
