Abstract

PURPOSE: To perform valve opening operation in accordance with temperature, by changing an electric current flowing in a heater, for heating a bimetal operated for opening a carburetor choke valve, through a switching circuit that changes duty ratio in accordance with the engine temperature.
CONSTITUTION: A bimetal 8 heated by a heater 19 is operated with an interlocking motion to a chock valve 5 in carburetor 4, and the valve 5 is opened in accordance with temperature. A switching circuit 11, to which the signal of a temperature sensor 13 for detecting engine temperature is input, is connected to the heater 9. Said circuit 11 is provided with such function that duty ratio from a pulse generator is varied in accordance with a temperatue signal to feed a small current to the heater 9 at low engine temperature and perform slowly opening operation of the valve 5.
