Abstract
In an automatic choke valve for an internal combustion engine the extent to which the choke valve is opened is controlled by a bimetal member located in a casing separate from the carburetor through which air is passed whose temperature is determined by the temperature of the engine. In addition, a heater unit is positioned in the casing for supplying heat to the bimetal member and the heater unit is controlled by switches operated by the engine temperature and by the atmospheric pressure around the engine.
