Abstract: A GAS PRESSURE CHARGED, TUBULAR DIAPHRAGM, PRESSURE ACCUMULATOR HAVING A FLOW TUBE FORMED OF SINTERED METAL PROVIDING COMMUNICATION PASSAGES FOR THE TUBULAR DIAPHRAGM AND A LIQUID UNDER PRESSURE IN THE FLOW TUBE, SO THAT THE GAS ABSORBS SUDDEN SURGES OF FLOW AND PRESSURE IN THE LIQUID FLOW LINE. THE SINTERED METAL FLOW TUBE IN THE ACCUMULATOR PROVIDES FULL OPEN COMMUNICATION BETWEEN THE LIQUID AND THE DIAPHRAGM BUT PREVENTS EXTRUDING OF THE DIAPHRAGM MATERIAL THROUGH THE OPENINGS AT HIGH GAS PRESSURES AND LOW LIQUID PRESSURES.
