ABSTRACT:
The method of providing an order of magnitude manufacturing cost reduction in the manufacture of fluid flow restrictors by employing components produced by punch press stamping operations. The flow restrictor is formed of a plurality of annular plates. Half of the plates are punched to form concentric rings of tabs at right angles to one surface thereof. The plates with and without the tabs are alternately stacked concentrically and brazed together to form the fluid flow restrictor having a central core communicating with the exterior surface through a plurality of tortuous paths.
