regulator of flow of gas cooler to the joule effect - thomson

摘要

Gas-flow regulator for a cooler, of Joule-Thomson effect type, associated with a cryostat, characterised in that the bimetallic needle 4 and 4 bis is internal to and coaxial with the tubular element 1, inside which it slides, in that the cold end of the cylindro-conical needle comprises three calibrated grooves directed longitudinally, in that the hot end of the needle 4 bis is fixed mechanically at a point out of the effct of the cold zone, in that the elements 1-4-4 bis each contribute in part to the flow regulation, in that the adjustment of the flow results from the position of the element 1 in relation to the element 5.
