に構成されている。 Conventional membrane valve type carburetors use a manual priming pump that sends fuel from the fuel tank to the fuel chamber of the carburetor upon starting, and a Teichler rod that pushes up the sensing membrane in the fuel chamber to open the fuel needle valve and the air bleed valve. When the priming pump is operated, the Teichler rod is simultaneously operated to smoothly introduce fuel by the priming pump.
ところが、このような膜弁式気化器においては
プライミングポンプとテイクラー杆を別個に作動
させなければならず、従つて両手を必要とし操作
が面倒である。 However, in such a membrane valve type vaporizer, the priming pump and Teichler rod must be operated separately, which requires both hands and is cumbersome to operate.

高くなる欠点を備えている。 Therefore, as shown in Japanese Utility Model Application Publication No. 55-108240, a priming pump installed in the carburetor is connected to the operating lever for operating the air bleed valve and sensing membrane, and the air bleed valve and sensing membrane are pushed up to control the fuel needle valve. A membrane valve type vaporizer has been proposed in which the opening takeler and the priming pump are operated by a single operating rod, but this has the drawback that the priming pump is assembled into the vaporizer, resulting in a complicated structure and high cost. It is equipped with

The purpose is to easily link the Teichler rod and priming pump.

を防げないように位置している。 The present invention will be explained below based on the drawings. 1 is the carburetor body, 2 is a sensing membrane, 3 is a fuel chamber formed above the sensing membrane, and 4 is rotatably attached to a support shaft 5 by a lever. , one end engages the fuel needle valve 6 and the other end engages the sensing membrane 2 . 7 is a fuel passage that connects the fuel chamber 3 and the fuel tank 8; 9 is a fuel passage that urges the lever 4 downward and connects the fuel needle valve 6 to the fuel passage 7;
10 is an air bleed passage connecting the fuel chamber 3 and the outside of the carburetor; 11 is an air bleed valve provided in the middle of the air bleed passage 10; 12 is a Teichler rod for moving the air bleed valve 11; It has an engaging part 12a and a push-up part 12b for moving the sensing membrane 2, and is rotatably attached to the vaporizer main body 1 or the sensing membrane cover 14, so that it can be operated from the outside of the vaporizer. It is configured.
In addition, since the Teichler rod 12 is always urged in the direction of arrow A by the force of the spring 13 except when pushing up the sensing membrane 2 (when preparing to start), the air bleed valve 11 does not open the air bleed passage 10. The closed portion 12b of the Teichler rod 12 is positioned so as not to prevent the sensing membrane 2 from operating.

のである。 The above is a membrane valve type vaporizer equipped with a conventionally known Teichler rod 12. The present invention further provides a fixing lever 15 on the sensing membrane cover 14 or the carburetor body 1, and attaches the Teikler rod 12 to the fixing lever 15 so as to be rotatable via a support shaft 16, and further fixes it to the operating portion 12c of the Teikler rod 12. A priming pump 17 made of a thin film elastic material such as rubber is held between the lever 15 and a support piece 15a for preventing the priming pump 17 from coming off is provided on the fixed lever 15 or Teichler rod 12. .

2c with fingers to operate the Teichler rod 12, the push-up portion 12b of the Takeler rod 12 pushes up the sensing membrane 2 and operates the fuel needle valve 6 which is interlocked with the sensing membrane 2 via the lever rod 4. , opens the fuel passage 7 and operates the air bleed valve 11,
Open the air vent passage 10 and at the same time open the Teichler rod 12.
The priming pump 17 mounted between the operating part 12c and the fixed lever 15 is pressed by the operating part 12c and the fixed lever 15, and the fuel in the fuel tank 8 is introduced into the fuel chamber 3 of the carburetor. Therefore, by remanipulating the above operation, the air accumulated in the fuel chamber can be discharged to the outside of the carburetor through the air vent passage, and the fuel chamber can be quickly filled with fuel. If the operation is stopped in this state and the engine is started, starting fuel is quickly supplied to the engine, and a smooth starting operation can be obtained.

安価に提供することができる。 In this way, in the present invention, a priming pump made of a conventional thin film elastic material is sandwiched between the fixed lever and the Takeler rod, and the priming pump is simultaneously driven when the Takeler rod is activated when starting the engine. Therefore, the Teichler rod and the priming pump can be operated with a single operation using only one hand, making it easy to handle and having a simple structure, making it possible to provide this type of vaporizer at low cost.
