ABSTRACT:
A fuel injection apparatus includes an axially movable member movable to determine the amount of fuel supplied by the apparatus. The member is acted upon by a weight mechanism including pivotal weights the force exerted by which is opposed by a governor spring adjustable from the exterior of the apparatus. Increase of the force exerted by the spring can result in sudden movement of the member so that temporarily too much fuel is supplied to the engine. This difficulty is minimized by providing a dash-pot which restricts the rate of movement of the member under the action of the governor spring at low engine speeds. The dash-pot is combined with a resilient means the force exerted by which is less than that of the governor spring at moderate engine speeds so that the dash-pot action is only obtained at low engine speeds.
