Abstract
For constant-speed cruising of a car, a throttle valve in a carburetor of a car is controlled by a motor-driven actuator through an improved variable-length lever mechanism. The variable-length lever mechanism has four arms which are movably connected through four elbows to form a changeable rhombic shaped lever. A linear actuator is interposed between a first pair of the four elbows at first opposing corners so that the distance between the first pair of elbows is expanded or contracted, whereby a radius in swing movement of the variable rhombic shaped lever mechanism is changed.
