Abstract
A speed limiter device for an automobile vehicle having a combustion engine comprising an air intake manifold provided with a throttle member manual control of the accelerator pedal type which acts on the opening of the throttle member and a connecting member between these opening devices and the throttle member. The limiter device comprises apparatus sensitive to a speed parameter of the vehicle for producing a speed signal, a comparator to compare this signal with a predetermined limit, and an amplifier for the signal supplied by the comparator. The amplifier controls a drive which is sensitive to the suction in the intake manifold and acts on the throttle member so as to keep the value of the speed parameter at the predetermined limit when the limiter device is engaged. The connecting member between the opening control and the throttle member has a substantially constant length when the limiter device is not engaged and a variable length when the limiter device is engaged.
