GAS FLOW RATE REGULATOR FOR JOULE-THOMSON EFFECT COOLER

摘要

gas flow regulator cooler, to Joule-Thomson effect, associated with a cryostat, characterized in that the bi-metallic needle (4) and (4a) is internal and coaxial to the tubular element (1) to within which it slides, the cold end of the cylindroconical needle comprises three calibrated grooves directed longitudinally, that the hot end of the needle (4a) is mechanically fixed at a point excluding the effect of the cold zone, the elements (1, 4, 4a) each contribute in part to the flow control, the flow control by the position of the element (1) relative to the element (5).
