CONTROL HEAD FOR A ROTARY-CELL FILTER ABSTRACT OF THE DISCLOSURE A control head for a rotary-cell filter, especially a filter having disks whose sectors are connected with overpressure and underpressure sources and upon which a filter cake collects upon immersion of the disks in the suspension to be filtered. The control head comprises a pair of relatively rotatable disks having contacting planar surfaces perpendicular to the axis of rotation of the filter, one of the disks of the head rotating with the filter while the other disk of the head is stationary. The disks are provided with passages opening at the planar contacting surfaces for sequentially communi- cating the individual filter cells with an overpressure and an underpressure source such that the interior of the filter cells, in a portion of their path before they emerge from the suspension, are connected with the underpressure source. According to the invention, means are provided such that the filter cells additionally in the region of the immersion in the suspension are connected with an underpressure source.
