ABSTRACT:
A fluid resistor for providing resistance to flow through a flow passageway is formed by cutting channels and open cylindrical recesses on the surface of and flow passage bores through a frusta-conical body to be seated in a tapered passageway section with the larger diameter end generally subject to higher system pressures than the smaller diameter end. The seating of the resistor body in a tapered passageway section seals and encloses the channels and recesses which then with the fluid passageways through the resistor body, comprise a restricted path for flow to proceed past the installed resistor, the recesses forming cylindrical chambers. Each chamber is tangentially by a channel and connected to another chamber by a bore that is coaxial to both chambers, the direction of the tangential intersection relative to the coaxial bore alternating, each upstream chamber inducing a spin that must be decelerated before the fluid exits the immediately downstream chamber, any even number of chambers being used as space and desired performance may require.
