摘要： A pulsation absorbing device and method of making a pulsation absorbing device is disclosed. The pulsation absorbing device includes a pressure vessel having a resilient diaphragm mounted therein together with an inlet associated with one end of the pressure vessel and an outlet associated with the other end of the pressure vessel. A spool is mounted within the pressure vessel inwardly of the resilient diaphragm and intermediate and in communication with the inlet and the outlet to carry fluid from the inlet to the outlet. The spool and the resilient diaphragm define a pressure chamber therebetween which is in fluid communication with fluid carried from the inlet to the outlet through holes in the spool. A helical wave band is disposed on the spool for accommodating flow through the holes in the spool and defines a plurality of helically spaced flow accommodating openings. With this arrangement, at least some of the flow accommodating openings of the helical wave band are in communication with the holes in the spool after the helical wave band has been spirally wound upon the spool in accordance with the disclosed method.
