Abstract
In order to retard the closing movement of the throttle valve (2) without significantly impairing the running of the engine, this closing movement is controlled as a function of the vacuum upstream and downstream of the throttle valve (2). In doing this, an air feed device automatically feeds additional air to the feed duct (1) downstream of the throttle valve (2) when the vacuum there falls sharply. This device has an additional air inlet (18) arranged downstream of the throttle valve (2), which inlet is connected by way of an inlet line (19) to a control valve (20) preloaded in the closing position. The latter is designed so that in the event of a sharp increase of the vacuum on the inlet (18) it rapidly opens in order to immediately counteract this increase by an additional air feed. <IMAGE>
