Claims

[Scope of Claim for Utility Model Registration] 1. In a fixed bench lily type vaporizer equipped with an air passage that supplies air to an air bleed part connected to a main nozzle, an air chamber communicating with the air passage and increasing or decreasing the volume of the air chamber An accelerating device for a carburetor, characterized in that it is provided with a movable member that moves the movable member in a direction to reduce the volume of the air chamber by interlocking the movable member with the opening operation of a throttle valve of the carburetor. . 2. The interlocking mechanism includes a driven plate coaxially supported with a drive cam that opens and closes the throttle valve, and interlocks with the drive cam in a normal rotation direction to open the throttle valve. The movable member is configured to be rotated in the normal direction against a return spring, and the movable member is connected to the driven plate so that the movable member is operated in a direction to reduce the volume of the air chamber by the normal rotation of the driven plate. At the same time, a cam portion is formed on the driven plate to prevent the throttle valve from closing when the driving cam crosses the driven plate and reverses, and further communicates the air chamber with the air passage. 2. The accelerator device for a carburetor according to claim 1, further comprising a one-way valve and a parallel jet interposed in the conduit for allowing air to flow from the air chamber to the air passage. 3. An intermediate plate is coaxially supported with the drive cam and is connected to the drive cam via a torque spring, and when the drive cam rotates in the normal direction, the driven plate is pushed by the intermediate plate and rotates in the normal direction. ,
Claim 2 characterized in that the forward rotation of the driven plate is restricted during the forward rotation of the drive cam.
Accelerator device in the vaporizer described in.
