초록

At preferably circular filter cartridges, where pleated filter material is placed around a centrally arranged perforated tube, this filter material can be sucked to collapse if the pressure gradient through the material becomes large, whereby the advantages having a pleated filter cartridge with a relatively large filter surface and a very little volume are lost. One means for preventing such collapse is using a separator which is arranged in each pleat of the filter material, whereby the separator includes a rigid organic foil formed in a pyramidal plea...

1. In a separator arrangement for filter cartridges wherein a pleated filter element is disposed around a centrally located perforated tube and wherein separators are located in the pleats of the filter element, the improvement wherein the separators each comprise an elongate member providing substantial rigidity and extending along substantially the entire length of the filter pleat in which the separator is located, said separators each including pyramidal pleats therein which extend generally transverse to the filter pleat in which the separator is lo...
