ABSTRACT:
The invention relates to a filter for regenerating oil, especially from combustion engines, with an exchangeable cylindrical filter-cartridge, being of filter-tissue-paper wrapped tightly around a thin-wall-carton-tube. The filter-cartridge-center is supported by a rubber-tube, being slightly smaller in diameter than the carton-tube. The thin-wall-carton-tube will be ruptured by the oil-pressure existing on the outer circumference of the carton-tube, at such weak places caused by the channels running lengthwise the rubber-tube, making the oil-flow through the filter-cartridge possible. The filtered oil will collect in channels passing to the exit.
