Filtration arrangement for e.g. microtechnological applications, has multi-way rotary valve with connection points at rotor surface with varied angular spacing

摘要

Connections (A-J) made at surfaces facing a rotor (R) and connecting sections (a-d), are characterized in position by their center points. Of adjacent connections and connecting sections, one or more center points has/have different angular spacing, in relation to the direction of rotation about the rotor axis. Connections are formed as recesses extending over a circumferential angle of 0.5 alpha to alpha , where alpha is an angle of rotation. The smallest extent is 0.5 alpha . The greatest is 4 alpha . When the filter is flushed with a second fluid, 10 angular connections are employed, with fluid switching, to provide appropriate working and flushing flows through the different filter sections.
