Figures 1 to 7 relate to the first embodiment of this invention, with Figure 1 being an overall configuration diagram of the valve control device for the carburetor, and Figure 2 showing the air force acting on the valve when the amount of intake air is small. Figure 3 is a cross-sectional view of the Chi-Yoke valve opening/closing mechanism when the air pressure is weak, and Figure 4 is the same cross-sectional view when the amount of intake air is large and the air force applied to the Chi-Yoke valve is strong.
The figure is an explanatory diagram of the operation when the check valve is fully open when viewed from the direction of the arrow in Figure 1. Figure 5 shows the function when the check valve opening is 20 degrees.
Fig. 6 is an explanatory diagram of the same effect when the valve opening is 30°, Fig. 7 is the operating state of the three-way solenoid valve, and the operation of the boost switch, vacuum switch, and temperature switch. FIG. 8, which is an explanatory diagram showing the relationship with the state, is an overall configuration diagram of a valve control device for a carburetor according to a second embodiment. 3...Chiyoke valve, 15...Chiyoke valve opening/closing mechanism (negative pressure responsive type Chiyoke valve opening/closing means), 55...

気化器のチヨーク弁制御装置。 A negative pressure-responsive Chiyork valve opening/closing means that operates in the direction of closing the Chiyork valve due to negative pressure, a low load detection means that is turned on when the engine is under low load, a high load detection means that is turned on when the engine is under high load, and a predetermined It has an engine temperature detection means that turns on when the engine temperature is below a predetermined temperature, and a delay means that operates so as to keep the low load detection means on for a predetermined period even in a high load state. 1. A carburetor check valve control device, characterized in that the negative pressure-responsive check valve opening/closing means is configured to operate for a predetermined period after a load state changes to a high load state.
