PURPOSE: To lessen the danger of closure to assure regular operation and to eliminate the need for frequent cleaning by providing the filter nozzle with means for enabling filter disks to assure the passages where the velocity component in the tangent direction of liquid occurs.
CONSTITUTION: This filter nozzle 1 having the annular filter disks 18 is provided with the passages 28 in a radial direction where the filter disks 18 guide filtrate and the passages 26 which penetrate the filter disks 18 and where the filter disks guide the filtrate. The filter disks 18 are further provided with centering pins 22 in order to assure the passages where the velocity component in the tangent direction of the liquid occurs. Consequently, the danger of the closure is made smaller than that with the known filter nozzles and consequently, the regular operation is assured and the need for the frequent cleaning is eliminated.
