Abstract
A device for filtering a liquid synthetic material. The device has a housing, a feed channel, a discharge channel, and backflow channels. The feed duct is subdivided into split-feed channels (A,B). The cross-section of the orifice of the split-feed channels, where they open into the filter chambers, is smaller than the normal cross-section of the feed channels.
