With the help of a mechanical control valve (the proportional controller), the opening and closing of
the inlet valve is continuously varied in relation to the actual air demand. The airend provides com‐
pressed air for connected consumers.
This continuous delivery regulation minimizes fuel consumption of the engine. The load and fuel
consumption of the engine rises and falls with the air demand.
