ABSTRACT:
A filter has circularly arranged filter elements open on both ends mounted between two separation plates in a filter housing. The plates separate the raw liquid inlet end from a clean liquid discharge section and separate both of these from an outlet end for the dirty liquid. Both ends of each filter element are connected through passages in the separation plates with the inlet and outlet ends. Rotary valves are connected nonrotatably with each other to open and close the connections between the filter elements and the inlet and outlet spaces. Only one rotary slide valve is provided on each side of the separation plates facing away from each other. The rotary slide valve on the admission side covers fewer passages than the rotary slide valve on the opposite side. The total number of passages covered by the rotary slide valves is the same as the total number of filter elements.
