THE INLET PASSAGE COMMUNICATES WITH A CENTRALLY DISPOSED CHAMBER HAVING A POROUS COMPRESSIBLE ELEMENT SURROUNDING THE CHAMBER. A PERIPHERAL ANNULAR GROOVE SURROUNDS THE POROUS ELEMENT AND COMMUNICATES WITH THE OUTLET PASSAGE. LIQUID OR GAS IS ADAPTED TO FLOW THROUGH THE INTERSTICES IN THE POROUS ELEMENT INTO THE PERIPHERAL ANNULAR GROOVE TO THE OUTLET PASSAGE. A MICROMETER ADJUSTMENT MEANS IS PROVIDED AT THE OTHER END OF THE RESTRICTOR FOR ACCURATELY CONTROLLING THE SIZE OF THE INTERSTICES OF THE COMPRESSIBLE ELEMENT AND THEREBY CONTROLLING THE FLOW THROUGH SAID ELEMENT. A CHART MAY BE PROVIDED WITH EACH RESTRICTOR SO THAT IT IS MERELY NECESSARY TO TURN THE MICROMETER ADJUSTMENT MEANS TO A PREDETERMINED SETTING IN ORDER TO OBTAIN THE DESIRED FLOW OF LIQUID OR GAS THROUGH THE RESTRICTOR.
