TEMPERATURE SUPPLEMENTAL PULLDOWN MECHANISM FOR CARBURETOR AUTOMATIC CHOKE

摘要

The carburetor has a conventional automatic choke construction heating a bimetallic coil by engine exhaust stove heat to permit the slow opening of the choke valve during cold weather starts; a supplemental temperature responsive power means at times overrides the bimetallic coil closing force to open the choke to various settings as a function of ambient temperature changes; and includes time delay means to provide a gradual actuation of the valve.
