Description

[Brief explanation of the drawing]

Figures 1 to 3 show examples, Figure 1 is an explanatory diagram when the water temperature is low and the air temperature is medium, Figure 2 is an explanatory diagram when both the water temperature and the air temperature are low, and Figure 3 is an explanatory diagram when the water temperature is low and the air temperature is high. FIG. FIG. 4 is a graph showing the opening degree of the throttle valve and the idle opening degree of the throttle valve with respect to water temperature in the embodiment of the autochoke device according to this invention, FIG. 5 is a graph of the conventional autochoke device, and FIG. FIG. 7, a graph showing the deformation of the Tx element with respect to temperature, is a schematic diagram of a conventional autochoke device. In the figure, 2 is a throttle valve, 4 is a rack gear body (throttle valve linking body), 5 is a first wax element, 6 is a cam follower, 7 is a throttle lever, 10 is a cam body (throttle valve linking body), 11 is the second wax element, 17
is the second piston.

Claims (1)

[Scope of utility model registration request] In an auto-choke device for a carburetor, during a cold start, a first temperature-sensitive deformable body that deforms in response to engine cooling water temperature closes a chock valve and places a throttle valve at a fast idle position via a linking body. and a second temperature-sensitive deformable body that deforms in response to the temperature so that the fast idle position becomes a position with a small opening degree when the temperature is high. An auto-choke device for a carburetor, characterized in that an auto-choke device for a carburetor is interposed between the chock valve linking body and the throttle valve linking body.
