Title:
BACKFLUSHABLE LIQUID FILTER
Document Type and Number:
WIPO Patent Application WO/2014/115081
Kind Code:
A1
Abstract:
The invention relates to a backflushable liquid filter, especially for fuel filtration of an oil burner, with a filter cartridge 6 arranged in a filter housing for separating a liquid inlet E from a filtrate outlet A, and with a backflushing device 20 for the backflushing of the filter cartridge, comprising an operating shaft 21 being rotatable around an axis. In order to create a back¬ flushable liquid filter with good filtration capacity, a plurality of filter candles 7 in the cartridge are arranged on a pitch circle with a perforated plate 8 being associated with the open ends of the filter candles. The operating shaft 21 functions as a flushing passage 23 for fluidic connection of the flushing head 22 to a flushing outlet 17 and has a flushing head 22 being movable as a result of an axial movement of the operating shaft 21 from a neutral position into a flushing position, in which the flushing head 22 butts against the perforated plate. The operating shaft 21 is axially displaceable relative to the flushing head 22 and the fluid connection between flushing head 22 and flushing passage (23) is openable or closable as a result of an axial displacement.
