One of the disks is fixedly mounted inside the housing. The second disk is cinematically coupled with the drive for setting it in rotation. The faces of the disks are divided into sectors. Alternate sectors are provided with through openings. The ports of the sectors of the movable disk interposed between the sectors with through ports of the unmovable disk receive gates.
