ABSTRACT:
An improved automobile engine carburetor in which a portion of the fresh air flowing into a carburetor main housing is bypassed through an auxiliary housing encasing a coiled bimetallic strip for controlling the position of a choke valve, so that the interior of the auxiliary housing may be maintained below a temperature at or above which the bimetallic strip may be heated to an unduly high temperature resulting in an earlier malfunction or failure. The improvement essentially comprises a first air passageway for letting fresh air into the auxiliary housing through an inlet provided upstream of a venturi throat in the main housing, a second air passageway for letting the air out of the auxiliary housing back into the main housing through an outlet provided downstream of the inlet of the first air passageway and a valve provided in the auxiliary housing to close one of the first and second air passageways to stop the flow of fresh air into the auxiliary housing when the temperature of the air in the auxiliary housing is below a predetermined level, while opening the first or second air passageway to allow it to resume the flow of fresh air through the auxiliary housing upon elevation of the auxiliary housing temperature to the predetermined level.
