Abstract

Flow restrictors are provided with known flow rates at given pressures. A flow restrictor is surrounded by a tubular sleeve having open ends. A fluid such as air is supplied through the restrictor, and the sleeve is simultaneously compressed, until a predetermined pressure across the restrictor is reached, at which time compression is stopped.
