ABSTRACT:
A flow meter for metering the air quantity aspirated by an internal combustion engine including a metering valve element constructed as a box-like cylindrical segment pivotably mounted in a flow tube of the engine. The valve element has a radial transverse wall oriented transversely relative to the direction of the air stream in the flow tube, side walls oriented parallel relative to the direction of the air stream and a curved cylinder wall connected to the radial transverse wall and the side walls. The transverse, side and curved cylinder walls define a recess which opens in a direction opposing the direction of the air stream. The flow meter thus constructed possesses the advantage of producing a nearly linear characteristic curve.
