FIELD: machine building.SUBSTANCE: pulsation damper is the flattened tube from flexible material the internal surface of the tube wall of which contacts without gap. During operation under the action of liquid pressure the tube expands, and the required gap for liquid passing is formed. Under these conditions it forms the vessel and creates resistance to flow, which are distributed along the whole length of the tube. Depending on the pressure and flow rate this gap changes the sizes, being adapting to external conditions.EFFECT: invention is efficient both at low, and at high flow rate and pressure; at high pressure it practically does not resist to flow, the pulsation damper made with this element, smoothes pulsations approximately 200 times, it is completely flow-through and has the minimum volume that allows to configure to another solvent very quickly.5 dwg, 1 tbl |
