Anordning for trykk- og strömningsmengderegulering av et kompressibelt eller inkompressibelt medium

摘要

An assembly of a first expansion stretch, a first throttle, a second throttle and a second expansion stretch have respective metal casings and elements defining the flow paths therein composed of engineered ceramics. The throttle are adjustable and the assembly can be used effectively to control pressure and flow rate of compressible or incompressible fluids which can have solid particles entrained therein.
