ABSTRACT:
The air induction tube of an internal combustion engine has an air flow rate meter which is displaced pivotably by the air stream. Connected to the pivoting element is a pressure cell which provides the restoring force for the moving element. The pressure of this cell is determined by the pressure in an air bypass line and by the actuation of valves connected to a constant pressure source. The bypass line also contains a pressure control valve which controls the amount of fresh air fed to the engine and a flow valve whose displacement is coupled to the air flow rate meter.
