Abstract
A throttle valve operating mechanism according to the invention has two functions one of which is a dashpot function to dampen the closing rotation of the throttle valve of the carburetor thereby achieving reduction of harmful compounds such as HC and CO contained in the exhaust gases from the internal combustion engine during deceleration of the same and the other of which is to open the throttle valve by a predetermined amount from the initially set nearly closed position when an engine driven power consuming device such as air-conditioner compressor starts to run during idling of the engine. This throttle valve operating mechanism is very compactly made by employing integrated construction.
