Abstract

This invention relates to flexible loading filters for cleaning oily liquids and allows for a simplified design and improved cleaning quality. In the filter housing 1, between the perforated partitions 3 and 4, elastic loading 2 is placed. Under the movable partition 3, an additional partition 13 with openings 14 and a collector 15 for removing contaminants is placed. Corrugated tube 10 for removal of contaminants is placed in load 2. When the loading is regenerated, the rod 8 moves up the partition 13, which closes the holes in the partition 3 and with its help squeezes the load 2. When moving upwards together with the valve stem 11, the pressed oil products flow down the tube 10, through the perforation 12 they enter the partition 13, from which are removed through the openings 14 to the collector 15, and through the pipe 16 are removed from the housing. 4 il.
