Device for controlling speed of an engine

Abstract

In a carburetor of a motor vehicle engine having an accelerating pump for supplying additional fuel when an accelerator pedal is depressed to a large extent, the accelerator pedal is connected to a slider which is connected through an accelerating pump cable to a swing arm for actuating the accelerating pump via a link and a lever. The slider is connected also to a throttle lever through a throttle cable. The throttle lever is coupled to a throttle shaft of a throttle valve by means of a torsion spring. When the accelerator pedal is depressed, the throttle cable and the accelerating pump cable are pulled, and the control lever is turned to rotate the throttle shaft by way of the spring in a direction toward an open position of the throttling valve so that the engine is accelerated, while the accelerating fuel pump is operated through the swing arm, the link and the lever so that an increased amount of fuel is supplied by the pump. Since the throttle valve and the accelerating pump are operated separately by way of the respective cables, the throttle shaft can be rotated with a small torque and the speed control can be carried out exactly without delay.
