DEVICE FOR AUTOMATICALLY REGULATING A CHOKE VALVE IN A CARBURETOR FOR AN INTERNAL COMBUSTION ENGINE

摘要

Disclosed herein is a device for automatically regulating a choke valve mounted in a carburetor. The device comprises a housing fixed to the body of a carburetor, a bimetal coil provided in the housing and connected to a choke valve shaft urging the choke valve to a closed or open position, an electric heater device located adjacent to the bimetal coil, and a heat conductive member interposed between the bimetal coil and the heater device. Each surface of the heat conductive member is kept in contact with both the heater device and the bimetal coil. Particularly, the bimetal coil is formed in a conical shape and mounted on a retainer, thus being operable to press the heat conductive member with its compressive spring force so as to receive the heat output from the heater device efficiently and quickly by direct heat conduction.
