Abstract
A fluid flow resistor includes: a body having entry and exit fluid flow ports, and an internal fluid flow path fluidly extending between the entry and exit fluid flow ports; the internal fluid flow path having a first spiral fluid flow path in a first spiral direction, and a second spiral fluid flow path in a second spiral direction opposite the first spiral direction; each of the first spiral flow path and the second spiral flow path having a plurality of discrete flow chambers fluidly connected in series via interconnecting fluid flow restriction passages; the first and second spiral flow paths having a connecting fluid flow path therebetween; the fluid flow resistor being configured to resistively permit fluid flow from the entry fluid flow port to the exit fluid flow port via the first spiral flow path, the connecting fluid flow path, and the second spiral flow path, in succession.
