ABSTRACT:
A governor sleeve is axially displaceable on a stationary governor shaft and has an inner space which is defined by one end of the governor shaft and which communicates with the inner chamber of a pump housing charged with fuel. The inner space varies in volume drawing thereinto and discharging therefrom fuel in response to axial displacement of the governor sleeve. There are provided, according to the invention, first channel means for providing restricted communication between the inner chamber and the inner space, second channel means for providing substantially unrestricted communication between the inner chamber and the inner space, and valve means operable to allow only said first channel means to establish the above-mentioned restricted communication upon displacement of the governor sleeve in the direction to produce contraction of the inner space and to allow at least the second channel means to establish the substantially unrestricted communication upon displacement of the governor sleeve in the direction to produce expansion of the inner space in order to prevent an acceleration jerk and smoky exhaust.
