Abstract
A unitary device for controlling the rate of throttle closure and for preventing after run of an internal combustion engine is provided with simplified structure, the structure using a single shaft assembly for both functional operations. The shaft assembly is operatively connected to a diaphragm assembly which moves in response to forces acting to position the shaft assembly. The shaft assembly is an axially aligned and concentrically arranged combination, and includes a first shaft element which acts against the diaphragm assembly to bring a carburetor for an internal combustion engine slowly to its curb idle setting upon throttle release from some running condition. A second shaft element of the shaft assembly is controlled by a solenoid. The second shaft element acts against the diaphragm assembly upon ignition system de-energization, and permits the closure of the throttle below the curb idle setting of the carburetor. Quick release means are provided in the diaphragm assembly for venting any air compressed by diaphragm movement toward the off position of the device.
