FLOW RESTRICTOR

摘要

The present invention relates to a flow restrictor for insertion into the inlet of a pipe to restrict fluid flow within said pipe to a predetermined maximum: The flow restrictor is comprised of a tapered tubular hollow body portion having a smaller diameter and a larger diameter end. A cover plate is attached to the larger diameter end. An aperture having a predetermined cross-sectional area is located in the cover plate. The smaller diameter end is open to fluid flow. The predetermined cross-sectional area of the aperture determines the predetermined maximum fluid flow.
