Abstract
A temperature-responsive control device for carburetors in which a heat-generating body produces heat as the engine is started from the cold state to heat up a heat-mass through an annular contact portion. The heat-mass temperature then rises with a certain time lag to the rise of the temperature of the heat-generating body. A thermo-wax unit is heated by the direct contact of its heat sensing portion with the heat-mass or through a contacting flange in a manner to isolate and float the heat-sensing portion to make a temperature rise substantially in conformity with the engine warming up characteristics or approximating as much as possible the same, to dismiss the choke mechanism and the fast idle cam at adequate timing through the action of the actuating rod. In consequence, it is possible to obtain a good driveability. When the engine is re-started in the heated state, the thermowax has been cooled approximating the cooling characteristics of the engine to avoid excessive enrichment of the mixture to ensure a safe re-starting of the engine.
