Backflush filter, in particular for filtering lubricant oil

This invention relates to a backflushing filter, particularly for filtering lubricating oil. Filter candles 22 which are open at both ends 24, 34 are disposed around a rotary shaft 1 in the filter housing 11, 12, the interior space of which filter candles can be acted upon in filtration operation by a sludge which flows into the backflushing filter 10 . A cleaning device is moved in conjunction by means of the rotary shaft 1 , and comprises an upper flushing cock 27 and a lower flushing cock, which communicate with an outflow valve via the rotary shaft 1 , for cleaning the filter candles 22′ during a backflushing operation. The upper flushing cock 27 is offset by an angle in the direction of rotation in relation to the lower flushing cock 37 . A lower closure element 38 which is moved in conjunction is associated with the upper flushing cock and is for the filter candle end face opposite the latter, and an upper closure element for the opposite filter candle end face 23 is associated with the lower flushing cock. The filter elements 22′ can be reverse-flushed in opposite directions and at different times by the flushing cocks and closure elements. The flushing cocks and closure elements are moved inside annular deflection hoods 60, 70.
