The lever 4 which opens the or each throttle valve 2 to a limit set by a stop 11, against the bias of a spring 10, entrains a lever 5 biased by a spring 7 after an initial valve opening thereby to increase the force necessary to open the valve. The spring 7 biases the lever 5 to engage a lever 6, positioned by a cable 8 or an engine or vehicle speed responsive motor 9, which sets the valve opening angle at which the lever 4 entrains the lever 5. <IMAGE> |
