The mechanism opens the throttle valve of an engine carburettor on deceleration, having a pneumatic capsule actuating the throttle as the result of pressure reduction in the intake, exerted via a valve calibrated to a set level of pressure reduction. The capsule has a diaphragm causing the throttle to shut again via an elastic component during the complete closing cycle. This is supplemented by a compensation spring during part of this cycle starting from the fully open position under the action of the diaphragm until the spring, which is integral with the diaphragm, is pressed against an adjustable stop under the effect of the reduced pressure. This effect is delayed by a valve in a tapping from the pipe between the capsule and the calibrated valve.
