Abstract

A flow rate meter which serves to measure a quantity of air aspirated by an internal combustion engine via an air intake tube. The flow rate meter includes a housing, in which a flow conduit having a measuring body is disposed, the measuring body being pivotable about a bearing shaft in accordance with the flow of the medium counter to a restoring force and being joined via at least one strut to a damping body, which in the form of a movable wall defines a damping chamber with respect to the flow conduit. A retaining groove is embodied in the damping chamber wall and is form-fittingly engaged by a retaining section of an elastic stop body. A stop section of the stop body protrudes into the damping chamber and limits the movement of the damping body.
