Abstract

A vacuum-boosting device for motor vehicles fitted with vacuum-operated load systems, the vacuum being provided by the engine air induction in the case of a petrol engine or by a suitable vacuum pump (34) in a Diesel engine. The device acts to increase the rate of evacuation of the load system (15) when the vacuum of the engine is weaker than a predetermined value, by increasing the idling revolutions of a petrol engine, or acting on a throttle valve (19) in the air inlet (18) of a Diesel engine so as to create a vacuum in the induction manifold to assist the vacuum pump (34) in evacuating the load circuit.
