Abstract (en)
[origin: WO2015180815A1] A filter device having at least one filter element (3) accommodated in a filter housing (19, 21, 61) which has at least two attachment points (A, B) serving alternately to supply non-filtrate and to remove filtrate, wherein by means of a reversal device (15) the fluid stream, which changes direction by way of the attachment points (A, B), passes through the filter element (3) in only one predefinable direction, characterized in that the reversal device has at least one valve slide mechanism (15) of which the valve piston (17), guided in a valve housing (27; 63) and controlled by the respective stream of non-filtrate in the assigned attachment point (A, B), frees the passage of the fluid stream from the unclean side (23; 77) of the filter element (3) to the attachment point (A, B) that is attached to the clean side (F) of the filter element (3).
