Abstract

A thermostatic valve, used in an engine for introducing warmed air to the engine and air to a slow-port passage of a carburetor, has a valve casing defining therein first and second compartments. A first valve member is disposed in the first compartment to control the introduction of the intake vacuum or the atmospheric pressure to a negative pressure motor mounted on a throat of an air cleaner. A second valve member is disposed in the second compartment to control the communication between a float chamber and the slow-port passage of the carburetor when the temperature of the air introduced into the engine exceeds a preset value so as to prevent excessive richness of an air-fuel mixture.
