ABSTRACT:
A solenoid actuated device to permit a carburetor throttle valve to close below the curb idle position upon deactivation of an ignition system for an internal combustion engine and to prevent electrical grounding by the device when it is out of contact with the throttle arm. The solenoid actuated device has an armature mounted in a housing for movement between energized and deenergized positions and a shaft extending through the housing is mounted within the bore of the armature for movement therewith. The shaft is in contact with the throttle arm adjacent one end and an electrical lead extends from the other end of the shaft. An insulating sleeve is positioned between the shaft and armature to prevent electrical grounding of the shaft when the shaft is out of electrical contact with the throttle arm. The insulating sleeve and shaft therein may be adjusted longitudinally relative to the armature to control the position of the throttle arm. The lead wire from the shaft extends to a source of electrical energy and upon grounding of the shaft when in contact with the throttle arm, electrical energy may be supplied to other selected electrically actuated devices, such as a means to retard the spark for a distributor.
