A circuitous path flow restrictor (10) having no moving parts includes a fluid director member (16) having a core (24) and a plurality of fins (26) extending from the core and defining alternately axially offset notches (50, 52). The fluid director member is encircled by a containment member (54) such that a serpentine fluid flow path (58) is defined therebetween to provide a fluid flow resistance level equivalent to a simple orifice of much smaller diameter. The fluid director member can be made by a precision casting process for economy of manufacture. |
