Abstract
A throttle valve driving mechanism comprising an actuator disposed near a throttle valve shaft, and an oscillating slide block mechanism disposed between an actuator shaft and said throttle valve shaft. Said oscillating slide block mechanism comprises a throttle lever provided at one end thereof with a roller, an actuator shaft disposed in a position on a straight line between said throttle valve shaft and said roller at the time when the throttle valve is fully closed and a certain distance away from the center of said roller toward the center of said throttle valve shaft, a rotatable lever secured to said actuator shaft, said rotatable lever having a groove within which said roller slides freely with small clearances, the center of said throttle valve shaft, the center of said roller and the center of said groove being arranged in the same direction when the throttle valve is fully closed. Said oscillating slide block mechanism is adapted to ensure a higher resolution of the opening of the throttle valve in a range of rotation of said actuator corresponding to a range of small opening angles of the throttle valve, and to give a higher speed to the action of the throttle valve in a range of rotation of said actuator corresponding to a range of medium or large opening angles of the throttle valve.
