Ce second chapeau d'extrémité est muni d'une sortie d'échappement 13 et de joints d'étanchéité 10, la tige 11 supportant à l'aide d'un coussinet 14 et d'un palier de butée une turbine hydraulique 16 entre le chapeau d'extrémité 12 et la bague adjacente 7. La turbine hydraulique 16 comporte deux bras 17 s'étendant radialement, chaque bras comportant of the filter. This second end cap is provided with an exhaust outlet 13 and seals 10, the rod 11 supporting by means of a bearing 14 and a thrust bearing a hydraulic turbine 16 between the end cap 12 and the adjacent ring 7. The hydraulic turbine 16 comprises two arms 17 extending radially, each arm comprising

Cette turbine hydraulique 16 est reliée à un élément creux 17 entourant ladite tige et s'étendant à travers l'élément de filtrage en étant supportée par la tige 11 à l'aide d'un coussinet 18 à l'endroit de la bague 7 adjacente à l'entrée 2 du bottier 1. L'élément creux 17 est profilé de manière à comporter une partie 19 adjacente à la surface intérieure de l'élément de filtrage 6 et o l'élément 17 est pourvu d'une série de fentes, de trous ou d'ouvertures 20. L'élément creux 17 est également pourvu d'un élément de brossage longitudinal 21 supporté par l'élément creux à l'aide de bras appropriés 22 ou similaires Lélément de brossage est adapté pour ètre en contact avec l'intérieur de l'élément filtrant pour enlever de celui-ci la matière filtrée. Un carter d'entratnement 23 entoure la turbine 16 et comporte une paroi radiale 24 ainsi qu'un joint d'étanchéité pour rendre étanche la zone d'entratnement de la turbine vis-à-vis de la zone de filtrage sauf à travers l'élément creux and rotates the turbine. This hydraulic turbine 16 is connected to a hollow element 17 surrounding said rod and extending through the filter element while being supported by rod 11 by means of a bearing 18 at the location of the adjacent ring 7 at the inlet 2 of the shoemaker 1. The hollow element 17 is profiled so as to comprise a part 19 adjacent to the internal surface of the filtering element 6 and o the element 17 is provided with a series of slots, of holes or openings 20. The hollow element 17 is also provided with a longitudinal brushing element 21 supported by the hollow element by means of suitable arms 22 or the like The brushing element is adapted to be in contact with inside the filter element to remove the filtered material therefrom. A drive housing 23 surrounds the turbine 16 and has a radial wall 24 as well as a seal to seal the drive area of the turbine vis-à-vis the filtering area except through the hollow element

The flow of water, when it sweeps the filter element and enters the hollow element through the slots, carries with it the debris and the filtered material which has been removed from the filter element by the brush , and this material is then discharged to
